Sharkfins were allowed in 2010 and banned for 2011

[eternal kettle]

why were they?

technical refresh?

[zinc bison]

Part of a techinical refresh, yes

Also because of the f-duct being banned and DRS being introduced

plus its structural

if a genius can explain what this helps with performance, ill givr you my noble price

[opaque arch]

could be use for flow reattachement to reduce drag - cant really determine without any experiementation or analysis

[prime mortar]

thats pretty cool, thanks for posting this

[buoyant pollen]

im pretty sure that thing adds drag. and with the wheel wake it doesnt do anything ig

There's an official mercedes w06 one as well

They did say that Mark's driving style strengths were in high speed corners. Plus the RB7 was a downforce monster. I think it was the only car that took Silverstone's T1 flat out with the DRS open

Trying to build a "successor" to the unraced 2010 TF110 prototype based on the 2012 spec regulations.

Currently basing it off of the 2012 RB game model, trying to figure out what to do regarding the sidepod, engine cover, and rear wing config

Nose has already been swapped over to something similar to the TF110, still need to move rear wheels up a bit to shorten the wheelbase

specifically posting about this cause some I'd like some guidance regarding what the TF110 might have been updated to in a 2012 spec, and I'm not really well versed in the 2012 regulations at all

[opaque arch]

make a proper model if you want to do proper CFD

stop using blender or maya

any kind of mesh modelling

switch to parametric one

[karmic gate]

Just because you do a 3d model do it not mean you want to do cfd

[opaque arch]

Then what's the point of it - unless you make games, but you don't need regulations to do that

[karmic gate]

Showcase, make renders, make livery and it is fun

I always want regulations so I can make the most acuret Showcase model

I use regulations when I do stuf for clients too

I use regulations for this too

(Wip)

[eternal kettle]

the point of it is to make it look like it belongs in the 2012 field, I do have full creative direction on this, however I'm trying to keep it grounded

[prime mortar]

no way your trying to argue with qvist designs

[zinc bison]

When was the last time a driver broke a bone in a race?

Schumacher in 1999?

[prime mortar]

not sure about race injury but ricciardo at zandvort last year he broke his wrist in fp2

[tall wyvern]

I mean it’s true, no car is designed not in NX or catia so

[quick wind]

This is a pretty unconventional way of doing it - keep it up wanna see the end result - what's the end goal?

[prime mortar]

obviously, but seeing that qvist isn’t a aerodynamicist (i’m sure he has a solid understanding of aero) he doesn’t need to use cfd like a f1 team or someone who is designing aerodynamic bits

but sure if he wants a realistic result of his 2011/2012 toyota f1 car mock up, he should use cfd to get the most realistic results. but i’m sure the main reason he is doing this project is to find some concept with the car that hasn’t been thought of

[lucid vortex]

Grosjean broke his wrist during the horrible 2020 crash

[opaque arch]

Since u are saying about what to do with the sidepod, rear wing, etc I assume u are trying to achieve a specific L/D goal else..... this is not really technical, it's more like blender modelling and making things that look "fast"

[tall wyvern]

Can you do stuff like curvature and draft analysis in blender? I have no idea.

[frank birch]

Does anybody know the race pace of the teams for the Vegas GP?

[eternal kettle]

friend of mine wanted a a “custom” model for a game, not really meant to be anything serious but because its based on the red bull f1 2012 gamemodel i wanted to give it a but mire variance

however I’ll probably end up rebuilding a majority of the model

[opaque arch]

thats easy then - just follow the reference volumes and make whatever u want - like in a game +/- 2 mm of slot gap between flaps wont matter right unless u want it to fully fit the regulations

im working on that model rn

[raven dock]

I made the model and it's pretty cool

does anyone wanna make a car, but have no regulations, and make like, a championship

[karmic gate]

What do you mean

[raven dock]

2026 regulations

livery design boutta go hard

[noble sentinel]

True

[eternal kettle]

I would but I would designa tractor lmao

[raven dock]

well there's no restrictions, and I have all the stuff to do the engine packs

[eternal kettle]

so for shits and giggles i could submit a late model stock car and call it a day

get to make smt highly illegal, but insanely fast

[short ether]

F1 doesn’t need active aero

Get rid of the hybrid system as well

[prime mortar]

as much as i love v10s getting rid of hybrid systems would be a step back. really i think hybrid turbo v8’s that rev to 15k would be perfect. because it brings back high revving 8/10 cylinders, while keeping more modern stuff like turbos and hybrid power units

[prime mortar]

f1 cars in 2077

[eternal kettle]

question regarding something that is less more in related with f1 but

whats the difference between a stock car spindle and a upright

because it sounds like formula cars generally use uprights and stock cars use spindles

and then the current next gen cup car uses uprights so now I'm just baffled

or is it because stock cars are just obscenely behind on tech

[opaque arch]

@tall wyvern I have a question regarding the regulations. As C3.10.1 H states that the last 40mm of the flap would be assessed and no part of the section visible from above may be more than 10mm distant from the section visible from below, does that imply that the upper flap must be 40mm overlapping the flap below - I am a bit confused.

Let's say the upper flap is only 30mm overlapping the flap below, there would be 10mm that doesn't comply the regulations assuming it's talking about the perpendicular height.

I am assuming it's talking about all the points at the last 40mm not a single point at the last 40mm.

[tall wyvern]

Because it says ‘assessing each section indepentendly’, it means each wing element by itself. So the suction surface must have a positive Z direction in the last 40mm and the normal distance between the suction and pressure surface of any flap element in any y plane (a section) must be less than 10/15mm - so it’s element normal thickness.

[next path]

So that's just thickness

Ideally, should u get variable thickness?

U get thicker flap at the middle to get more central load and thinner at the outside

or just make it 10mm for the whole flap

@tall wyvern

5mm wouldn't do much?

[opaque arch]

so last 40mm must not be thicker than 10/15mm

[short ether]

Whats do the cars do this specific led light pattern sometimes?

[opaque arch]

No one can see that

[prime mortar]

well i’m guessing it’s the red light on the back of the car your talking about

[short ether]

The ones on the wing

[prime mortar]

they blink at the same time as the rear crash structure light

[short ether]

They do this pattern sometimes

[prime mortar]

i mean i can’t see it

could you send a video of it?

but the red lights always flash in the rain no matter what

in a dry race they flash when the pit limiter is on, if the driver is harvesting their battery, and i don’t remember but if there is a yellow flag they might flash too.

[opaque arch]

@tall wyvern How about this? Is this gap distance

[tall wyvern]

Yes that one is slot gap between elements at every y plane

[opaque arch]

some good progress

[tall wyvern]

Yes but in the direction normal to the surface, not closest point

[opaque arch]

so like this

the point is created through direction along curve

[tall wyvern]

Yep, but I would just split the last 40mm and then offset the split. If the other surface goes through it then it’s too big. An offset is always normal (unless you add deviation)

[opaque arch]

I did that with other sections so it's alright - just extra steps

[tall wyvern]

If you do it in a section then you only know that section is legal

If you do an offset you know the whole surface is legal

[opaque arch]

I will check

I did a sweep - that also do the job

[tall wyvern]

Not a bad way of doing it

How did you make the 40mm line?

[opaque arch]

i made a point along curve

ye - some of it is not legal

[tall wyvern]

And then what? Isoparameter on the surface to sweep?

I would probably parallel the trailing edge on the surface and then sweep an implicit line with reference surface with the parallel as the guide curve and the surface as the reference surface (at 90 degrees)

[opaque arch]

I did this

[opaque arch]

I made a curve that is tangent to the trailing edge and project it

[tall wyvern]

Projected it to what?

[opaque arch]

to the surface

upper section

then sweep using that as a guide

[tall wyvern]

You did the tangent curve in plan view 40mm forward of the trailing edge and then projected that downwards?

[opaque arch]

Not plan view

Just spine

I am not sure whether this is a good way or not

[tall wyvern]

How can you project a curve onto a surface which the curve is already on?

[opaque arch]

I think I did it on the solid so it's slightly off

[opaque arch]

The red and yellow curve is the projected geometry

[tall wyvern]

Projected from what though? Unless it was in plan view I don’t see how you could project a curve onto that surface from the trailing edge of the same surface

[serene plover]

Why does Abu Dhabi suit Ferrari the most

[opaque arch]

I dont how to explain but this is what i did

the sweep is under the flap

[opaque arch]

who said that

[serene plover]

Well I’ve j been hearing that Ferrari will be quicker at Abu Dhabi, even the sky sports commentators said

[opaque arch]

they are all yappers

everyone has been saying mclaren has the best car through the season and lando always bottles win - tbh the mclaren wasn't even dominate at all - maybe in quil. But in terms of race pace everyone is just so close

[rotund kelp]

That doesn’t mean they don’t have a slight advantage

[opaque arch]

Advantage is minimal to the point which is negligible

[karmic gate]

finding limits of 2026 regulations

have a intresting floor edge

using cfd now

[tall wyvern]

I guarantee you can’t find the ‘limits’ of the regulations as one person, especially from blender..

Looks pretty though

[karmic gate]

i mean i try to find the limits of regulations by my understanding

[short ether]

Why does some F1 teams dash's can't really tell if there is a red flag, and just shows a VSC warning instead.

[long crystal]

what is this

👀

[tall wyvern]

So they’re breaking the rules by doing CFD before the 1st of january?

[long crystal]

that's what I first though

i asked him and he said, 'i'm sure'

[tall wyvern]

I’m sorry that’s bs

[tall wyvern]

Bullshit

[long crystal]

yep

What's the best Autodesk software for CAD modeling?

[tall wyvern]

All the teams use either catia 3dx or Siemens nx

[opaque arch]

FIA never sends CAD model as a stl or blender file lmao, blender is a toy, what's wrong with u guys?

[opaque arch]

U sure that guy is real, why would someone admit cheating lmao? Fia is likely to publish a newer revision of regulations in Jan so why would teams start working on it

[opaque arch]

Fusion and Inventor are pretty good for entry to mid level

[opaque arch]

I wonder how u gonna mesh a dirty blender stl

[hollow kettle]

Hello guys, I have always wanted to be a formula one mechanic. I know the basic path, get experience somehow, Motorsport engineering, then apply. But i still don’t have a great idea on what to do. Any tips or pointers would help tremendously. Thanks!

[opaque arch]

go to linkedin ig and look for the requirements

[hollow kettle]

I can never figure out how to use LinkedIn, where would i do that. How do i add people to get advice because i have heard it’s good to do that

[opaque arch]

just make an account

and get connections

[hollow kettle]

It won’t let me for some reason

[opaque arch]

wdym

it should look like this

[hollow kettle]

Let me double check

Where do i go from here

When i search, how do i connect

[opaque arch]

Search random people

u probably didnt add ur school or company stuff so linkedin wouldnt recommend any people to u to connect

[hollow kettle]

Should i have done that?

[opaque arch]

Ye i guess so

[hollow kettle]

Wdym, like should i search f1 teams?

[opaque arch]

search sth like aerodynamicst - the point is to get the linkedin algorithm to find people that u maybe interested

maybe search like f1 mechanic

[hollow kettle]

Ill try that

[opaque arch]

i can be ur first connection if u dont mind

[hollow kettle]

Sure

I remember now

This is what i kept seeing

[opaque arch]

ye i guess linkedin forces u to add someone u actually know

just gimme ur profile link then i can add u

[hollow kettle]

So i can’t contact f1 mechanics or similar?

[hollow kettle]

Kk

[opaque arch]

i think u need at least 10 connections

[hollow kettle]

So who can i make connections with

[opaque arch]

ur school

ur company

[hollow kettle]

Ohh

Ok

[opaque arch]

linkedin has some labelling system which labels different people (like people u connected is 1st, 2nd is people that u work with / study / 3rd is like random people that u dont know) i am not pretty sure about this but it should sth similar

when u make an account i think u are only able to connect 2nd

i think they did this to prevent people using linkedin to scam

[hollow kettle]

Ohk

So 10 people for 3rd?

[opaque arch]

ye i guess so

[hollow kettle]

Alr thanks

[hollow kettle]

I sent my link in your dms, any other tips for my goals?

[opaque arch]

i send random dms to people on linkedin to ask for advice

[hollow kettle]

Ok, so when i reach 10, I’ll do that. Thanks for everything!

[karmic gate]

idk how he who do the re mesh do it but it works well

[opaque arch]

Openfoam?

[karmic gate]

it was a joke

[karmic gate]

he use autodesk cfd

[opaque arch]

Ahh ok

autodesk abandoned Autodesk CFD sometime ago

[karmic gate]

damn

it is so much better then anything i have

[opaque arch]

Most teams either use OpenFOAM or Siemens Star CCM

How many cells is he using

i think u need at least 50mil for the entire car

[karmic gate]

idk

[opaque arch]

Go ask him

If it's less than 50mil, the results aren't really representative

ideally aim for like 75mil + especially it's a openwheel formula car

Is he an aerodynamicist

[karmic gate]

he is a student

he is Automotive Engineering Student

[opaque arch]

just make sure to apply correct boundary conditions else the results could be totally useless - adding MRF's are also useful to analyse tyre wake but that's an extra/optional thing. I am not sure whether u can do that in Autodesk

[opaque arch]

u sure that he doesn't have a student license for ansys or star ccm+? Most schools have school licenses

[karmic gate]

he do have school licenses

[opaque arch]

Autodesk is free if u have a student card so it doesnt really count

technically u can setup ur simulation for free

using autodesk cfd

[tall wyvern]

There is an fia model and there are 5 or 6 people or so at each time working on it as part of prescribed work by the fia, but the results are open to all the other teams because it’s supposed to inform the regulations without giving a team an advantage for having worked on a critical part early.

[karmic gate]

@opaque arch are you good at understanding the regulations?

[opaque arch]

Mid

[karmic gate]

do you think you can have surfaces?

[opaque arch]

I guess so, @tall wyvern @karmic gate need help

[tall wyvern]

That rule means you can’t have a double tea tray for example.

[karmic gate]

What do that mean

[tall wyvern]

You can’t obscure the bib with another surface from above or below

Like this

[karmic gate]

Do that part not count as main floor

Parts that are not part of bib can still obscure

[opaque arch]

It says any surface so ig it means all surfaces

[karmic gate]

It mean just floor bib and floor bib trim to floor is later

[opaque arch]

Anyway it means that u cant have anything that is above or below the bib

as it says that it has to be fully visible from above and below so nothing can block it

[karmic gate]

Body do block it

I think you should make all parts individually and in the trim part do it say the combined allowed shape

[tall wyvern]

Yes exactly

[opaque arch]

What does ii mean - does this mean the bottom surface of the nose has to be flat

[tall wyvern]

Anything in an individual rule applies only to that part of it says bodywork (pre trim) or aerodynamic components (post trim)

[tall wyvern]

Look at the BGP car, it’s to stop that

I couldn’t find a good picture hence the Aston Martin one

[opaque arch]

What's the BGP car Brawn GP?

[tall wyvern]

Yep

[opaque arch]

That's the bib of BGP

so how does BGP stop that

[tall wyvern]

There are parts of the bib (between the top and bottom) which can’t be seen from above or below, which the bib rule above stops.

[karmic gate]

Oof i do have a concave curvature, looks like i need to change

[raven dock]

how do I generate high pressure under a sidepod, and low pressure above it

the wing mucked up the flow, and I just cant seem to find a way to fix it

[opaque arch]

Do u know how an airfoil work

[raven dock]

not really

all I know is doing the underside

the front wing is great, it generates downforce, but then around the sidepod the air goes to hell and messes up, and makes a turbulent rear wing airflow

[long crystal]

calm down mate

nobody said that

we are not comparing Blender to CAD or something lol

I know the differences

no, it is to detiald for a 3d printer to be able to do that

in a score out of 10, this is 1/10 accurate

there are no accurate blueprints unless you get the pdf with all profile views from CATIA or whatever program it was took out

[short ether]

Bring back the V10’s and smaller cars

F1 is not about efficiency

It’s about pushing engineering to the limits and driver skill

[short ether]

Manual gearboxes should be allowed again

[frozen peak]

If they were to bring back manual, drivers most likely wouldn't be able to cope. They learned to drive this way and Alonso would probably be the only one to be able to drive this way

[quick wind]

Drivers would be able to cope...

It's just a bit of a reverse on technology I suppose. (Inefficient)

Bear in mind there is still clutch control on the wheels.

[upper ivy]

for a NEW lower formula car you'd probably have to directly to go the manufacturers like like Tatuus or Dallara or Lola

[woven cove]

What about older ones?

[upper ivy]

used racecar sites like the one you linked above

VERY old ones probably rather at auctions

[celest plaza]

you cannot say ‘it’s about pushing engineering to the limits’ then say V10’s and manuals should return

The V6’s are heaps ahead technologically, sequential semi is also miles ahead of manual

What do these winglets do

By the air box

[opaque arch]

To create a vortex to fight against side force? Since they don't have a fin

[opaque arch]

It should do things that a fin does

[frozen peak]

They should bring back the fins that go all the way to the rear wing, yes or no

[edgy anchor]

I don't like sharkfind so no

[hollow kettle]

Should I go to oxford brookes if I want to be a formula one mechanic

and whats the salary like

[opaque arch]

like 150k - really depends on the team and specific job title

[amber kraken]

First time seeing this unique rear wing concept

[sinful sparrow]

what the heck

[hollow kettle]

that is so ugly 😭

[raven dock]

I'll do it

anyone wanna have a copy of my virtual formula series regulations?

[edgy anchor]

It was tested too

[raven dock]

it deserves to be burned

splitting the wing like that makes such a terrible effect of turbulence in the model I made

[edgy anchor]

Done

[tall wyvern]

Actually this is something I’m a little surprised hasn’t been explored more. I assume it’s too much of a loss of downforce. The problem of following isn’t because of some made up turbulence, it’s because of the upwash from the car in front reducing the angle of attack or the following car (plus the lower total pressure in the following car). The idea of a CDG wing is that the upwash from the wing is counteracted by a downwash in the centre by the other wing tips.

[raven dock]

lower total pressure

if theres a lower pressure than expected it's counted as turbulent flow

[tall wyvern]

No it isn’t lol

Turbulence is velocity in directions away from the bulk direction

[raven dock]

rigjt

so what you've said was a lower pressure

and I'm assuming this would typically mean, less pressure than what's wanted, which is described by my dad, and my teacher, as a turbulent flow, I.e: non laminar, also known as turbulence

[tall wyvern]

And both your dad and teacher would be wrong. Total pressure is static pressure (internal energy) plus dynamic pressure (kinetic energy). When the air is worked by the car, some of this total energy is lost to friction. Thus cars travelling in the wake behind the car have less available pressure to turn into downforce.

Turbulent flow vs laminar flow is completely different. Call the local flow direction x. In laminar flow, the local fluid elements are all moving parallel in the x direction. In turbulent flow, there are fluid elements with y and/or z components of velocity. Turbulence intensity is a function of how great these normal components are.

[raven dock]

anyway, I found the perfect angle to blast air at my scale model of the 2022 mclaren to visualise the aero effect of the rear wing and the rear wing's arms

the unexpected but welcome addition to this test was that I also watched the airflow around the rear tyres

[short ether]

Gives dallara DW12 Vibes

[opaque arch]

lmao have u heard of the reynolds number, low pressure doesn't mean it's turbulent

[raven dock]

the Reynolds number is the next thing I'm supposed to be learning in terms of CFD

[opaque arch]

ur freestream velocity isn't even aligned to the x axis

so it's not even accurate

[raven dock]

it was a sharp blast from 0 to 90 ish degrees

I just wanted to push air around and find out what would happen

[opaque arch]

it's not an accurate representation tho

[hollow kettle]

Do you study aerodynamics

[opaque arch]

He's an aerodynamicist who work for merc

I believe

[hollow kettle]

Woah

[short ether]

Damn these 2000's F1 cars look so beautiful

[short ether]

Is that Kimi or Montoya?

[pallid acorn]

Juan Pablo

[ancient juniper]

love pretty color

[tall wyvern]

sorry what is this supposed so show? q coloured by velocity magnitude?

[signal lava]

probs the air flow

[signal lava]

formula e ahh type rear wing

[opaque arch]

Tyre Wake?

[ancient juniper]

cheap way of showin turb

doesnt capture work done but in star TKE is expensive to resolve

the sims residuals are trash i dount its right, havin issues finding a CFL number that works and making my continuty decrease

[tall wyvern]

But what’s the criterion?

What decides what is coloured

[ancient juniper]

the sim itself

im running that geometry thru a turbulence modelling software

[ancient juniper]

if that answers your question

[tall wyvern]

Ok but defined how?

[ancient juniper]

by a mesh, so that geometry and the surronding volume/space is broken down into abt 40 million finite cells and then told to solve over

[ancient juniper]

its cfd

[tall wyvern]

Ok let me put it another way - why are only some bits blue?

[ancient juniper]

thats slower velo than the freestream, by a good bit

the fs is set to an inlet condition of 35mph and that air at best is 15 mph

so its stalled, its been worked on and is moving vastly slower than air around it

tbh this is an idea given to me by a senior in aero engr so im still learning too

[tall wyvern]

The bits that are white

Why are they not blue.

[ancient juniper]

because they are faster than 0 to 15mph which the displayer is set to resolve

So i could have it all be blue if i wanted by changing those bounds

Its just a scene, you display literally anything

You can*

[tall wyvern]

I see. It would be more useful to use CpT to show what you’re trying to show.

[ancient juniper]

cpt?

[tall wyvern]

Coefficient of total pressure. It’s a reflection of how much energy has been lost to the air. Velocity magnitude isn’t good representation because there’s no reference of what the total energy is.

[ancient juniper]

alr icic

ill play around w cpt next time im workin on that sim then

[ancient juniper]

@tall wyvern

[tall wyvern]

That number is much much much too big

[ancient juniper]

Ill do more reading into it then

btw my refrence pressure is 101325pa (1atm)

[ancient juniper]

im gonna hand calc ts cuz i agree an E5 number is bonkers

[warm axle]

2005 mclaren

🤤

[tall wyvern]

If you think about the definition of coefficient of total pressure being (local stagnation pressure - freestream static pressure) / freestream dynamic pressure, what’s the maximum the coefficient can be?

[ancient juniper]

assuming my flow is generally incompressible (which it is) finding q isnt hard

freestream static pressure is the static p of 101325pa

im going to have to pick apart my pressure scene for a local stag pressure

ideally a spot of high pressure to find a maximum

[tall wyvern]

The maximum is always 1 - q is dynamic pressure, p is static pressure. Subscript 0 is total/statnation, subscript _inf is freestream.

If coefficient of total pressure is (p_0 - p_inf) / q_inf, and p_0 is q+p, then with no losses, this becomes 1. It only goes down from 1.

How far below 1 shows how much energy the flow has lost, in coefficient form. That’s why it’s useful.

[ancient juniper]

ok cool

ill be on my laptop later today and ill play around w my sim to see whats wrong

im pretty sure its gonna be my reference pressure thats messed so ill start there

call me if im wrong but my p_0 is going to be 101325pa if i am running @ sea level ye

[tall wyvern]

You can just use a gauge pressure for static pressure, so then p_0_inf would just be q_inf

Which makes p_inf 0 so then CpT in the freestream before losses is just q_inf/q_inf again, so 1

[hollow kettle]

Do stickers affect f1 aero, and how much

[frozen peak]

They affect it only if they aren't on properly. Because then air gets stuck under them, creates drag and bla bla bla

[hollow kettle]

If they aren’t on properly, does it create much drag

[frozen peak]

Not a substantial amount, but at this level of performance it affects the car quite a lot

[hollow kettle]

Ok

[opaque arch]

since stickers have a different surface roughness - it could affect the skin friction

In cycling, people stick stickers since it reduces skin friction drag

[hollow kettle]

McLaren did a screen ad on their car right?

[opaque arch]

ye

that's not sticker tho

sticker has minimal effect anyways

[hollow kettle]

Why would they do that? Screens are heavy

[opaque arch]

It's sth like an Amazon Kindle not an actual screen

It's much lighter

And the car is probably under the weight limit so the team can play with the screens

[knotty geyser]

If their car is underweight add something helpful 💀

[opaque arch]

bro u get extra money if u put sponsours

[opaque arch]

If teams have this logic, then all the cars should be blank carbon and they should add ballast

@tall wyvern Since FIA published the issue 10, the Front Wing Adjuster System has been changed. It states that point A and B must be no more than 25mm from the forwardmost point of FW Primary Flap at their respective Y positions and within the volume of FW Primary Flap. "Does that mean my design won't work because the axis cannot pass through both points?" If yes, does that force the flaps to be parallel to the y axis? Or is there sth that i misunderstood. i am kinda confused.

The axis has to be parallel to the y axis right? Else the symmetry part would disconnect when rotating

[ancient juniper]

@tall wyvern pretty sure the issue w my sim is the cfl number and the timestep ive been displaying is after the sim goes to shit

my fsae team hasnt rlly ever used unsteady and im making it a project this winter break to make implicit unsteady work for us

hence why i havent shown u anything in a minute

[knotty geyser]

Oh yeah true i guess

[knotty geyser]

Yeah true

[raven dock]

where should I actually start for making an open seater car because there's so many places and I've never had to build an original one from scratch before

Also what is it that makes it open wheel, because the Aston martin valkyrie is classed as open wheel

[amber kraken]

Adding a statement to this video about Mark Webber's driving style. Apparently he was great when it came to aggressive cornering on long high speed turns

[karmic gate]

f1 wing concept in cad

(not within any regulations)

[ancient juniper]

ye

[karmic gate]

https://www.youtube.com/watch?v=gZDG-gljGmU

[opaque arch]

Is this from issue 9

I don't think the front wing active aero has been updated

[karmic gate]

Ye model is my issue 9 model

But they did make new rim

[vestal depot]

The power units are so underpowered that they're being forced to do this to get them faster than F2 cars

[opaque arch]

50 50 spilt is the dumbest idea

The ICE itself can already generate 850hp

And now it's being reduced to 500

[celest sinew]

are they trying to turn into formula E?

[opaque arch]

They don't know what to do for the next generation and they know they can't use the same engine for more than 12 years so they decide to do some changes

It's still the same powertrain technology

No major improvement

It's actually reverse in technology as most of the thermal efficiency comes from the MGUH

[celest sinew]

wow so we’re somehow going backwards

LOL

[vestal depot]

60-40 at most

And allow refuelling to make the cars lighter

They say they want to trim the weight yet they ignore the most obvious way to do it

[opaque arch]

I think the fuel energy flow is now about 4300MJ/H and they are reducing it to 3000MJ/H for the 2026 cars

theoretically the ICE power would drop to 558 HP

[short ether]

Whats a "FALSE NEUTRAL"?

[bronze scaffold]

its like an incomplete shift, a point between any two gears that isn’t actually the neutral selection

[bronze scaffold]

Currently working on designing an F1 car as a personal project - definitely will do iterative testing using CFD but is it also useful to create a physical wind tunnel in which i can put a 3D printed model inside?

[ancient juniper]

i mean it can be that hard to diy one, just matters what scale you want it (closer to actual scale the better) and what blockage percent ur willing to roll w

and reynold scaling the tunnel ofc

[marble stirrup]

The reynold scaling will be huge so I would already question the accuracy of results you will get, that is before considering the finish of the 3D printed model and then how you are going to measure or visualise the flow from the tunnel to validate? Is this for validation alone (checking CFD results) or for drawing information (independent aerodynamic insights)? If the former then you could probably get a certain level of use/ information out of it to confirm CFD results. If for drawing information you would need a large high fidelity 3D printed model as well as a series of accurate and calibrated equipment to measure forces. This question depends on the scale of the project you are going for and why you might want the wind tunnel.

[frozen peak]

Hotwheels already made a wind tunnel for car models up to the scale of 1:18. Not sure how acurate they are, they use water steam to visualize the airflow on the car and I think there is a switch wich determines the speed of the car, ergo the speed of the airflow and how it sticks to the car. Just wanted to point that out, but don't take it for granted because I never had one of those

[bronze scaffold]

In terms of purpose, it would be for validation of CFD results and comparison. The scale I’m thinking of is 1:18. I understand the worry is accuracy, that’s why I’m questioning the use of a wind tunnel at a small scale such as this. (other than the fact it looks cool to have my model in a scaled down wind tunnel)

[opaque arch]

It takes months to tune a real life wind tunnel so....

if u correctly setup a cfd case, accuracy is above 95%

but of course, u also have to tune the cfd

1:18 is too small

f1 cars usually run at 55.5m/s to validate cfd results. assume air density is same, i think u need 990m/s for the scaled down model if my quick calculations arent wrong

for a cheap windtunnel toy, the ground won't move so the boundary layer interaction with the floor would not be represented whereas in cfd u can assign that as a boundary condition

[bronze scaffold]

okay thanks for the info, i think I won’t do a wind tunnel then. Thanks.

990m/s is quite right to match the Reynold’s number😭 so yeah defo will not be doing that

[tropic marlin]

i know its been a while but thoughts on alpine becoming a customer team in 2026 and quitting on renault engines?

[merry delta]

unfortunate but not unexpected imo

it certainly isn't cheap to make F1 engines, and it's pretty obvious now that Renault didn't find it worthwhile to continue such

[tropic marlin]

its really sad but do you think alpine would profit from this

profit in the sense of uhh

points made

[bronze scaffold]

if they can implement it correctly, they should

[merry delta]

profit? maybe, maybe not
I do suspect that they will save a decent amount of cash since they don't have to develop an engine as well

[karmic gate]

f1 2026 concept blueprint

same but vector

[vast portal]

The sidepod area looks kinda weird

[hollow kettle]

What does the side pod even do

[vast portal]

Well it's got multiple purposes. One of them is aerodynamics and if I am not mistaken there is a cooling radiator in each of the sidepods.

I am pretty sure that the air from the turbo is directed to these radiators to cool the air a bit before it goes to the engine

[karmic gate]

Idk what is best for 2026

I will do cfd of it when done

[vast portal]

Yeah, I saw the official FIA 2026 concept and the sidepods were smooth and much longer

[karmic gate]

i wanted to try something diffirent

and the teams never do that fia do

[vast portal]

Yeah, I know

I was just curious because I have never seen such a unique design

[karmic gate]

williams 2022 and some 2021 cars did have it

[vast portal]

That's a good point

BWT Alpine Formula One Team (@AlpineF1Team) on X

We’ve been busy in the wind tunnel alright 😎

Last week, in accordance with FIA regulations, official Wind Tunnel testing of the 2026 BWT Alpine Formula One Team car (A526) began 💪

Twitter · Jan 7, 2025, 5:02 PM

[bronze scaffold]

Has this not been tested at all - done by eye?

also will you make a suspension with it

[karmic gate]

Done

[karmic gate]

I have not tested it yet, I did just make a concept within regulations first

[vast portal]

That looks amazing

[fair heath]

will sidepods be that style or do the regulation allow the current style

from the airbox to the back

[karmic gate]

We don't know how it will be but i thunk they will try some outwach concept

2024 sidepod is allowed but it is not needed when we don't have ground effect or beamwing

[old briar]

49

All five of us submit 49

[opaque arch]

This is not technical related bro

[ancient juniper]

😭

[dreamy haven]

nope

[quick wind]

Is that... fusion 360?

[zinc bison]

Does the car have to be symmetrical down the middle? What if a team wanted to trim out half a wing for a specific circuit, or only close one brake duct a bit?

[vast portal]

That is an interesting question

Well, wheel centres have to be arranged symmetrically, bodywork too. But to answer your question, in the 2025 technical regulations, I found article 3.2.3 saying that there will be exceptions for the asymmetrical angle adjustment of the front flap

[opaque arch]

Its ok for cooling and suspension geometry

[bronze scaffold]

is that pushrod front, pull back? (can't really see)

[bronze scaffold]

well there's always some ground effect

[karmic gate]

yes

[karmic gate]

ye

[bronze scaffold]

With the sidepod, you're forcing air down and into that raised bit near the rear wheel right?

(as in that's the theory)

(just saying the shape of it could lead to lift rather than downforce so that'd be intriguing to see in testing)

[bronze scaffold]

cool

with the rear since you're pushing air into that area it might be better to have pushrod as that clears space for airflow rather than obstructing it? yk

then alternate with pull in the front

[karmic gate]

im trying some new stuf on my other concept

[bronze scaffold]

woah

that's so cool

what software are you using for the design and renders

[karmic gate]

i did have this before

[karmic gate]

the last 2 pic do i use blender

[bronze scaffold]

cool cool

[karmic gate]

this is fusion 360

[bronze scaffold]

ah okay

would you recommend that platform for CAD

i only use Onshape atm, don't have a solidworks license

[karmic gate]

i think fusion is a good kinda professianl

[bronze scaffold]

cool ill give it a try

ur gonna do CFD on your designs right?

[karmic gate]

i did try cfd on my cad but did get error so i give up but i maybe will get help from other person to do in a other software

i did do cfd on my blender model long time ago

and i have done much updates

[bronze scaffold]

oh okay

[raven dock]

can anyone give me a hand with making a car

like a concept model

because I really am struggling with what I have because blender seems to be too much, so I have to wing it with 3DS but I'm still not too sure on how to use CFD stuffs myself

[bronze scaffold]

im assuming 3ds is a CAD software?

Normally with CFD you can find ones that are compatible with CAD files that you can upload and test on

so for me i use onshape for CAD and simscale for CFD, which allows upload of CAD files from onshape documents

with CFD, normally the platform has tutorials - if too complex there's loads on youtube as well

[bronze scaffold]

This looks way better than ur original sidepod design

well done

(i'm quite sure that sidepod was going to generate lift)

[raven dock]

I made a basic model so I can see the general shape of my rear wing and what it'll look like

but for some reason the CFD just doesn't work no matter what

[bronze scaffold]

like as in it's completely not working - 0 results at all?

[raven dock]

yeah

it's just like

either not loading anything or it's coming up that it's just non existent

[bronze scaffold]

i haven't used 3ds before so i'm afraid I can't really help

sorry

[raven dock]

gotta love Autodesk software

[bronze scaffold]

i tried downloading autodesk yesterday and my computer just wouldn't have it 🙂

[raven dock]

I was lucky to download it tbh

[karmic gate]

ye old was a bit bad, i did not know what sidepod that would work best but i think this would work well

[raven dock]

it seems to hate any computers with power, but it loads fine on my laptop

[bronze scaffold]

yeah this one looks better, definitely a more traditional approach

[bronze scaffold]

hmm maybe ill try again sometime

[karmic gate]

did try more outwach

[bronze scaffold]

i still can't get over how good that render looks though super impressive

[raven dock]

outwash is so much easier for me to do

[raven dock]

rendering models is so hard for me, but I can do lighting really well

[bronze scaffold]

honestly I have no rendering experience, just CAD stuff and some CFD, I will learn it eventually though

[karmic gate]

i always have same basic renders lol but i think my carbon finaly look good

[bronze scaffold]

the reflections on the chassis are cooking ngl

[karmic gate]

what do that mean lol

[bronze scaffold]

like as in it looks rly good

[raven dock]

I can't do reflections at all 😭

[bronze scaffold]

i can't do any rendering💀

[raven dock]

I can really effectively do bloom

[karmic gate]

blender doing it's magic

[raven dock]

my code for bloom basically makes it really good, without burning up graphics cards

[bronze scaffold]

breezy

[raven dock]

this is my current full model

and then I do everything else separately and make 4 different designs and pick the one that looks like it would be the best

[bronze scaffold]

that's the front wing main plate and the nose right?

[raven dock]

yep

[bronze scaffold]

honestly for fun I'd test out that massive chassis block in CFD

altho ig that would waste the limited hours i have on my current plan

[raven dock]

it's not been smoothed out yet, but I know how it'll end up once smooth

[bronze scaffold]

yeah

[raven dock]

I get 90 hours a month for it

I've wasted 20 trying to work it

[bronze scaffold]

i think i have 100 hours/month on mine

it's a free student plan though

[bronze scaffold]

20 hours is quite a bit to use though

[raven dock]

and I still haven't CFD tested my 2022 reg nodel

[bronze scaffold]

they should have like an appeal for recompensation

[raven dock]

honestly yeah

or at least some form of manual

I'm coding one myself

[bronze scaffold]

coding a manual?

[raven dock]

so it basically sends small spheres over surfaces, prints them making a tube, and allows visualisation

[raven dock]

VWT

[bronze scaffold]

wait you're coding a CFD environment??????

that's actually crazy

[bronze scaffold]

so it's for flow visualisation?

pretty cool

[raven dock]

yep

[bronze scaffold]

what programming language

[raven dock]

I just need to see if the flow is as it should be in my head

[raven dock]

C++

this is my old nose and wing model

[bronze scaffold]

wait but how will you determine if the flow stays attached or separated?

[bronze scaffold]

looks good

the suspension looks kinda funny on that model

[raven dock]

it's a chunky nose to keep it as low as possible, but push as much air down the side as I could

[raven dock]

it's just straight up 5 tubes

[bronze scaffold]

yeah i was thinking it looks like that

[bronze scaffold]

😂

you could use small lift generators that will generate downwash

a lot of teams have it

ig it would reduce effectiveness slightly

[raven dock]

I'm thinking for the final model im going to use flat sidepods like red bull this year, but also small vertical zero pod intakes like the 2022 mercedes

[bronze scaffold]

be careful with those..

lmao

tbf the vertical intakes weren't a bad idea

[raven dock]

I worked out how to do it before

[bronze scaffold]

im interested to see how u combine those ideas

[raven dock]

but nothing will ever be anything like the TM-01

that model was a... beauty

[bronze scaffold]

TM-01?

is that yours

[raven dock]

what makes it worse is that my dad showed it to an aerodynamics Jr at alpine

[raven dock]

yep

[bronze scaffold]

i have a feeling that this is going to be iconic

[raven dock]

Treiben Motorsport

[bronze scaffold]

cool

[raven dock]

I've found the file

and it opened

[bronze scaffold]

let's have a look shall we

[raven dock]

it's gonna take a good minute to load

that because I threw an actual engine model inside as well

[bronze scaffold]

that's so cool

[raven dock]

it's so bad

it was to calculate weight

[bronze scaffold]

ah

[raven dock]

it weighed in at 1.98 grams

[bronze scaffold]

umm

that seems

[raven dock]

so about 1980 KG

[bronze scaffold]

slightly off

okay

good

[raven dock]

it's so heavy

at least it could go fast I guess

[bronze scaffold]

wait what

1980kg

that looks off by a power of 10

that's massive

[raven dock]

like the lower limit is like, 798kg

[bronze scaffold]

for the whole chassis and engine

[raven dock]

but I guess i did something wrong

[bronze scaffold]

possibly

surely it can't be that overweight

[raven dock]

it's probably about 1000 kg

[bronze scaffold]

more likely

[raven dock]

or like, 1098 kg

[bronze scaffold]

i think your model needs to go through a serious weight loss regime

[bronze scaffold]

the front wing looks massive

so much downforce

[raven dock]

the suspension is incredible

the front wing is like

[bronze scaffold]

pull rod front pushrod back?

[raven dock]

0.3 metres long and 2.2 metres wide

[bronze scaffold]

width goes crazy

[raven dock]

I can't remember what I was thinking

[bronze scaffold]

pull rod front and push back is actually a good idea

[raven dock]

either way, it got a uh... minor face-lift for 2023

nothing too noticeable

[bronze scaffold]

that looks recognisable

[raven dock]

bits were modelled by the car from F1 22

[bronze scaffold]

ahhhh

[raven dock]

mainly the sidepods and intake

[bronze scaffold]

no wonder i can recognise it

[raven dock]

the floor was modelled from a guy that explained aerodynamics while building it

[bronze scaffold]

ah

[raven dock]

I have the beginning of the model lay out

[bronze scaffold]

these front wings are actually so large idk if its the scaling or smth

[raven dock]

i think its the FOV

[bronze scaffold]

ah maybe

cus the rear wing looks so mini compared to the front😂

i gtg but ur models look rlly good

[raven dock]

aight

I'll post up a model of the rear wing

[bronze scaffold]

have you done CFD for this model?

it'd be interesting to see where the CoP is

seeing as the front wing looks way bulkier than the rear

[bronze scaffold]

compared to CoG

[raven dock]

Cop?

I know centre of gravity

the idea was to make wildly proportioned stuff

[ancient juniper]

cop 🥳🥳🥳

its such a bitch to set up

my fsae team had to reach out to an indy team to get it right

[bronze scaffold]

centre of pressure

[raven dock]

fsae?

[bronze scaffold]

formula student competition

[raven dock]

which uni

[bronze scaffold]

formula 1 for students mini scale

[raven dock]

which uni tho

or college

[bronze scaffold]

@ancient juniper

[raven dock]

my dad's the head of it at his uni, so I know a little about it

[ancient juniper]

iowa state

@raven dock

[raven dock]

oh nice

[ancient juniper]

im one of the poor souls that does the majority of the cfd work for the car

[raven dock]

just remember, no amount of carbon fiber is too much carbon fiber

[ancient juniper]

one of our seniors and our team lead threw their heads at the cop report for abt a month

and we think we got it

[raven dock]

uhh

I drove the car one time

[ancient juniper]

aura

i steerd ours once back from an on campus recruitin event cuz we werent allowed to drive it

[raven dock]

one of the cars is housed at a motor museum, and hailed as a hero because the team got 20th with it

[ancient juniper]

🔥🔥🔥

we just auction all our old cars off to alumni and such for funding

the school doesnt rlly help us that much sadly but its wtv

[tall wyvern]

This would always be given as balance, aka % of downforce on the front axle - rather than centre of pressure

[bronze scaffold]

still interesting to see where it is though

the conclusions that can be drawn from both data tbf is similar

[tall wyvern]

I have literally always seen it as aerobalance and never centre of pressure, because the aerobalance is the functional parameter for laptime

[bronze scaffold]

ah i guess in that sense it’s more practical, my apologies

they are related though

[tall wyvern]

The three important force coefficients are front downforce, rear downforce, and drag. Sometimes sideforce but less so.

[raven dock]

Gang I just hit up with a whole new wing design

I wanna know how simple I can make the design, but it basically acts like it adds a winglet over the rear wheel

[raven dock]

I just realised it could also effectively reduce spray

[bronze scaffold]

lets see

[raven dock]

shape

atm I've got the shaoe

I need to cut the area for the adjustable flap out and refine the sharp edges

[polar fern]

Similar to the f2 wing

[raven dock]

no

the flat bits at the bottom sit over the wheel

it's a much wider wing now

[polar fern]

Hence similar not the same

In terms of the shape it’s very similar

[raven dock]

yeah

the top of the wing I see it

[opaque arch]

tinkercad quality

[polar fern]

I see it everywhere except urs goes further in at the bottom

[raven dock]

from the front view it's more noticeable the way it sits over the wheels slightly

[polar fern]

Wow so you’ve just changed the lengths of things a bit

Not some whole new design

[raven dock]

it's basic for now, because I'm still working on it

but the idea is that it'll cover the back of the wheel, allowing for a full wing length, hence it's a new design

[polar fern]

And increasing drag lots

[raven dock]

...

it's basic

and it's supposed to be for a higher downforce circuit

and circuits at higher altitudes

[opaque arch]

what is this autodesk app

looks like an unpopular app choice

[polar fern]

3ds max

[raven dock]

it's just 3ds max cus I gotta build my new PC

[opaque arch]

what software are u planning to use

[polar fern]

365 aud a month for it lol crazy

[raven dock]

I get it free because I'm a student

[polar fern]

Yeah I gathered that

As do I

[raven dock]

tbh I'll probably keep using it because I can view things in my vr with it, and actually see how big my objects are

[polar fern]

That’s a cool feature

[opaque arch]

no one would pay that - 75% of people are using student licenses

[polar fern]

Ik lol

Just saying it’s a crazily priced thing lol

[opaque arch]

they expect u to earn money by using their software - so it's a fair deal

[bronze scaffold]

yes this is key of course. what you were referring to with aerobalance is directly related to CoP you know - with aerobalance measurements you can find the centre of pressure at different phases in the cornering

so it doesn't make much of a difference which one you use

[tall wyvern]

Think what you want but it’s balance that’s used in the development process

[bronze scaffold]

just saying they are practically the same thing...

but you are correct on the fact it's used in the development process, so maybe stick to that - i'm just clarifying that they are both directly linked👍

[icy prairie]

does anybody know of any opportunities for a high schooler to do an internship at any team?

preferably software, but i would be interested in looking into all opportunities

[scarlet sapphire]

Try searching website of each team like sponsors also

Petronas also has internship opportunities

[bronze scaffold]

I’m having trouble trying to download fusion 360 for personal use

so i get on this page once i've completed all the data

click the link

and then it just takes me here

and i can't see any downloads anywhere

OH WAIT NEVER MIND IT'S WORKING

[raven dock]

let's goooo

[opaque arch]

student license gives u more functions but it's essentially the same

[bronze scaffold]

cool cool

im trying to download Ansys CFD for student now

But i’ve noticed autodesk also has a flow simulation thing too

so idk which one to use?

[ancient juniper]

use ansys

its more popular in industry therefore should mean ull get more meaningful results from it vs using a primarly cad software

[opaque arch]

the mesh limit is annoying

@tall wyvern is this illegal

[bronze scaffold]

okay thanks

[raven dock]

so

I'm gonna redesign the rear wing, and have to remove the tapered top edge for now, to allow for a DRS or active aero functionality, but with a little help, I've realised there may be a good point in having active aero on the diffuser too. anyone wanna help with this?

[tall wyvern]

Looks like it

[bronze scaffold]

I wouldn’t mind

[raven dock]

yippee

[bronze scaffold]

lmk what u need help with

[raven dock]

everything tbh 😭

lowkey hard building a car from scratch

[bronze scaffold]

np

i’m researching for my own project too so this will be good preparation

i’ve got all the theory down, just need to implement the ideas into CAD

i’ve made 4000 words of notes and that’s not even including my mathematical derviations😭

so i believe i’m well prepared

[tall wyvern]

I’m interested to see what you’ve written

[candid solar]

So this deal is denied
I mean 1b $ for Max

[sweet tree]

This is the wrong channel for that but yes

[bronze scaffold]

I can share if you’d like, its from various online sources and research papers - it doesn’t include most of the mathematical derivations as those are in my notebook and i’m still adding to it but there’s plenty

[bronze scaffold]

It also doesn’t include the extra knowledge gained from the physical textbooks i’ve read but provides a good basis with some complex considerations

[raven dock]

AI believes it could be successful

[bronze scaffold]

what could be?

[tall wyvern]

I am interested what you wrote

[raven dock]

the wing

this one

I've got to take off the tapered edge, and stuff for now, so it resembles more of a 2018 restricted wing

working on the body is coming on fine though

standard cockpit, no sidepods, done the intake and engine cover, no halo either

[bronze scaffold]

what about considering a dual-element wing?

you might be able to afford larger angles of attack and thereby increasing downforce

[bronze scaffold]

here's the aerodynamics section

it's still incomplete

the mechanical section is much more incomplete

it's quite basic really, I haven't included the advanced mathematical equations and textbook material for fluid flow around an entire body

i'm afraid those are in my handwritten notebook and also in the textbook itself

it's more like a beginner's guide I suppose

i'm gonna finish the mechanical section within the next few weeks and then add more to the aero

[tall wyvern]

Which textbooks have you used? It’s good you’ve done the work.

[bronze scaffold]

Well these notes are mainly from online sources

My handwritten ones are quite a bit better bc it includes all the equations

and they’re the ones which i’ve done using the textbook - which is Race Car Aerodynamics by Dr. Joseph Katz

[bronze scaffold]

Namely the Honda technical R&D research papers

It’s publicly accessible

plus various other research papers i think one was from student journal

but a lot of it was individual sites too to find out terms

[tall wyvern]

That’s good. I think you should try to get a copy of aerodynamics for engineering students by houghton and/or understanding aerodynamics by McLean. There are some things that you have incompletely understood that a proper textbook would help you with.

[bronze scaffold]

Thanks for the advice, i’ll have a look into those. Probably need to finish my current textbook first! Hopefully some of those incomplete understandings will be fulfilled(and then i can further with these textbooks you’ve recommended)

[tall wyvern]

Do these textbooks first or you wont fully understand Katz because it’s not an actual aerodynamics textbook.

[bronze scaffold]

Gotcha

Man they’re quite expensive though

I’ll probably only buy one - which one do you think is better?

[tall wyvern]

Houghton is easier to read, McLean is quite heavy. But McLean argues about why things are, rather than just telling you that they are. Which is good for understanding because you develop an intuitive sense of the physics. But houghton is easier, which is why I like them in tandem. They are the two f1 recommended books either way. On balance I’d probably say houghton initially.

[bronze scaffold]

Okay, thanks a lot for the advice, i’ll definitely look into it.

eventually i’ll get both, so i should probably start with the easier one then.

[tall wyvern]

Keep doing what you’re doing and it will pay off.

[bronze scaffold]

thanks man 🙏

[crystal axle]

what’s yall opinion on the v6 engine sound?

since i saw this video pop up on my tl and i had to ask over here cuz in my opinion it sounds kinda good but not as great as v10 engines

https://youtu.be/_buXFT-KZbE?si=AH30yw6L5BJDX_H1

[scarlet sapphire]

its seems to have sensitive steering

[crystal axle]

the track was wet so maybe he was driving a bit more sensible + this car wasn’t really that great of a car compared to the others of its season

[scarlet sapphire]

yes less developed maybe they are focusing 2026

[crystal axle]

well this is the old model so we don’t know what’s going to be the 2025 car model

i’m just looking at this livery and really enjoying it more without the fucking logos

[sweet tree]

they sound good imo

[torn field]

ferrari and renault sound the best

[raven dock]

I agree with the Renault

alpine is the upcoming team I support this year

I genuinely believe if they can get the sidepods just right this year, they could fight to become a championship team

[opaque arch]

Bro sidepod is just a small element of a car

Media has been overhyping it

[zinc bison]

list of times in f1 when the car stopped on the cooldown lap
All I can think of is Vettel/Stroll 2017 Malaysia

[thorny prawn]

I think also Hulkenberg Australia 2023

[short ether]

Perez Baku 2021

[raven dock]

how good did i do on working out the air interaction with a rear wing, because I'm sure there's at least five goofy things

[opaque arch]

I can't read this

[raven dock]

Quick notes where I correct myself about the way air would contact an object

[opaque arch]

no offense but i dont think anyone can understand
