The Mannesmann Giant Triplane was a German WWI super heavy transport project that was abandoned during early stages of development. Work on the aircraft started in 1917, alarming the Entente powers as they believed it to be a super heavy bomber capable of reaching New York. In reality the aircraft was designed as a transport. The aircraft was not completed before the end of WWI and thus never flew. The fuselage was completed, while the engines and wings were yet to be constructed and delivered.

Wingspan: 50m
Length: 45.7m

Speed: 130km/h
Range: 10,500km shock

The aircraft was to be powered by 10 engines.

how far into your stupid german superprojects are you

harsh tiger
#

How is a 47 meter long transport capable of crossing the Atlantic before the 1920s a stupid project?

#

Now let's see what America accomplished in the very same time period...

harsh tiger
#

Barling Bomber, American superheavy bomber project.

#

Not even 20 meters in length.

#

274km range.

#

More than 38 times less than the Mannesmann project.

harsh tiger
#

And also 4 years later.

outer oar
#

Orangetime try not to suggest a plane that isn’t German Italian or Japanese challenge (impossible)

harsh tiger
#

Yes, cause most of the other projects are downright boring.

icy niche
#

suggest like

#

idk

#

sst or smth

harsh tiger
#

True, but the SST ban.

icy niche
#

nothing's stopping you from suggesting them anyways

#

let's be honest i can't remember the last time one of these projects you posted got even considered by the devs

icy niche
harsh tiger
#

Well I research all these projects for fun, got a whole database by now, might as well post my research here just in case.

icy niche
#

exactly

#

why not post an sst anyways

harsh tiger
#

Who knows, might as well get added.

aeronautica devs when i suggest an aircraft that i can literally buy right now if i had the cash to: nuhuh

aeronautica devs when orangetimeexpress suggests the 723rd german paper project that's a shitty framework with a giant fuckoff cannon:

harsh tiger
#

How is it a paper project?

#

Entire fuselage was complete.

#

Also some of it survives to this day.

outer oar
fresh merlin
harsh tiger
#

Well there are like 10 other projects of similar proportions that actually did fly.

#

Find Riesenflugzeug projects.

harsh tiger
#

This for instance.

#

It actually flew.

outer oar
#

It kinda didn’t have a engine under the fuselage

radiant mason
harsh tiger
#

If not for the Versailles treaty, it would have been built.

#

Basically stupid regulations against technological innovation again.

#

wutdahell

outer oar
#

it theoretically could sure

#

but there's a reason we dont put early engines under fuselages

FINAlLY

#

How-

#

WHAT THE FUCK?!

harsh tiger
#

No wonder.

#

Got any additional info on it maybe?

Wheel.

outer oar
#

yeah something in me doubts it would have flown for very long

#

Also how in the actual hell are you supposed to taxi it

wheat zinc
#

Ehhh

#

It could've

harsh tiger
#

Sure it would have.

#

Again, similar designs were actually flown.

outer oar
#

yeah but uh

#

see this is uhm

#

A terrible design all around

#

Given that
You land at a 35ish degree angle? And have to taxi like that

#

Additionally you land a little too hard and your entire fuselage is in half

#

Additionally it is entirely a paper design whether you want to admit it or not. It wasn’t built fully and didn’t get past a frame, if it did, it would have seen little to no use before the surrender and probably before a mechanical failure ended it’s career because there was a reason we don’t put engines with big spiny things below where people go

harsh tiger
#

If it was in the process of building, it is NOT a paper project.

outer oar
#

It’s not like they could estimate that type of stresses very accurately, and without flight testing who knows what its range payload etc would have been

#

Also there is no way in hell that thing was getting more range out of it in WWI than a 737….

harsh tiger
#

Not sure about payload, but I guess if you fill it entirely with fuel tanks maybe.

#

It was meant to drop propoganda leaflets on New York by some accounts.

#

Those are not too heavy.

outer oar
#

yeah the vimy barely made it to Ireland from St John’s
Yeah I doubt it could make it to NY

harsh tiger
#

Germans were always a step ahead with their aircraft...

#

Probably won't be a 10,500km range, but 6,000km or so I would say is reasonable.

#

Depending on how the aircraft was configured.

#

Big BIG plane

carmine hamlet
#

A little better render on the tail

#

The stabilizer will be some thichness as well.

carmine hamlet
#

Wait... Where the 10x engines powering 5x props or are the extra props hidden behind... Kinda like most of the dornier engines?

Currently what I'm at...

Now, if we go to Mohr's discoveries with things such as Mohr's Circle and the Compatability Eqs, you to around 1882, which still is 3 decades before WW1

#

Then you have Finite Element Method whicj developes in the 50s and 60s, which only exists becausr electronic computers were coming out and FEA is a modular math. But it utilizes previously mentioned methods but effectively automates them

#

Despite that hand calcs

outer oar
wheat zinc
#

Which are usually 3

#

Which basically means that it's designed with 3 times the yield stress over what is the normal working stress

#

Because if SF was 1
Then anything above what is common would force the material to yield and begin plastic deformation if ductile, and break if brittle

#

So we pick 3

outer oar
#

Well you see here's the thinggggg

#

you are typically doing this with metal yeah?

wheat zinc
#

Any material

outer oar
#

okay so wood and fabric

wheat zinc
#

So the skin of an aircraft is really interesting

#

It absorbs ALOT of stress

outer oar
#

also random thought but good luck with trying to land with any componenet damaged or without engines

wheat zinc
#

Components in the 1910s was an Altimeter, a Pitot Static Probe, and the metric fuckton on the engineers station

outer oar
#

and you also have a engine below you

wheat zinc
#

But without the engines goes into the fact that mulit engines are usually designed to fly while missing a few engines

outer oar
wheat zinc
#

You'd be surprised

#

Some planes were capable on flying less than all engines

#

Not ALL but some

#

And considering the size of this behemoth, I wouldn't be surprised if there was some redundancy on the engines

outer oar
#

and engine unreliability

wheat zinc
#

Engine reliability goes for both sides of the war

#

But iirc the germans had more reliable engines than the Brits and French

#

Not by A LOT

#

But they were

#

And it was mostly due to the Zeppelins and how long and far they had to fly

wheat zinc
outer oar
#

Doesn’t mean anything

wheat zinc
#

The push pull or the Zeppelins

outer oar
#

Push pull

wheat zinc
#

Because the push pull was to correct Orange

outer oar
#

If anything it makes it more likely of mechanical failure

wheat zinc
#

Not for you

#

Which my bad if it did look for you

#

But the push pull had heat problems, but those could be dealt with

outer oar
#

True but still then

#

There’s a reason you see engines to the front sides and top of a aircraft

#

You never see them below

wheat zinc
#

That comes to clearance problems of the prop but that's a design choice I don't endorse

#

Personally my problem is I don't know where most of the weight is

outer oar
#

Where the engines are

#

Along that one axis

obsidian blade
outer oar
#

Which leads me back to
You land that a little too hard
You now an aircraft in half

outer oar
obsidian blade
#

MOOOOODS

wheat zinc
#

Which we already discussed being improbably due to engineering methods

outer oar
wheat zinc
#

G-Force is factored into that math

#

It's called a body force in the Cauchy Stress Eqs

#

My thing wasn't engines

#

It was fuel

outer oar
#

True

wheat zinc
#

That's nearly 90 hours of flight time with 10 engines

#

That's a FUCKTON of fuel

outer oar
#

Yeahhhh

#

Welcome to the problem I had with the range estimate

wheat zinc
#

Which could be accurate

#

I don't have a problem with the number, I have a problem with fuel location and storage

#

Because that's a MASSIVE point load

outer oar
wheat zinc
#

I've seen how they calculate range

#

It requires a lot of fun things

#

A lot of things have to be exact

outer oar
#

Im still doubtful they could even get close to 10k km

wheat zinc
#

So it's less of a practical range and more of a max theoretical range

lapis adder
# harsh tiger True, but the SST ban.

Suggest the Aerial Relay Transport System. Essentially a plane that can theoretically carry an infinite number of passengers by docking with one another.

#

Why was its designer allowed to cook is a mystery no one will ever solve, much like the designer of the TV-8 which was meant to be nukeproof.

wheat zinc

We forgot wake turbulence

forget suggestion blacklist, try to make that and you'll get fucking banned on the spot
