#whats the best vent/pre-cooler/nacelle set up for a super sonic recon plane similar to the sr-71?

i currently have a precooler, nacelle and shock cone intake

I believe in practice you need nothing but the shockcone. the other stuff is mostly just for fun. I wish it had a use but afaik nothing actually gets hot enough. With that understanding you will want to mix mk1 parts for the engine pods and use the mk2 parts for the main body. Just copy the wings.

just the shock cone is fine. Just one of those can feed more than 6 engines btw

pre-cooler keeps your engine cool, if u want looks then double precooler is fine

#

and use panther to have similar speed

I just wouldnt bother with the precooler. you can take it out and put fuel in instead. it makes no difference to the game.

#

it does, however, extend your flight time. Even a structural tube is better since it weighs less and produces less drag

#

if you are flying in lower atmosphere, engine is gonna be the first to overheat

#

and guess what precooler does

#

fix that exact issue

#

when have you ever had your engines overheat.... ever

#

I mean the jet engines

#

Ive flown at 1000 m/s in the upper atmosphere and my engines are the literal last thing to overheat. my rcs blocks overheat sooner and they arent affected by the precooler

#

they even say on the wiki that it is practically useless, this has been known for years

#

here is the data:

#

shock cone makes all the other intakes pitiful, not even worth using

#

regarding cooling, like I said, it wont do a damn thing.

#

there is probably no circumstance you are better off using the precooler

#

I say this as someone who dislikes this data and wishes other intakes were worth using or actually cooled vehicles properly or do the things they advertise

#

but oh well

#

admittedly ive never done endurance flights so in that case it very well might, I mostly stick with SSTOs

#

the thermal flux is over a much shorter time which likely is easier to dissipate

#

up to a point, if I had to guess

#

fair enough but the benefits look marginal

#

youre talking the difference between 20u-50u of air and 10u-30u of air

#

at that point id choose whatever looks the coolest :P

#

performance isnt super important

#

I agree, the shock cone looks like crap on a lot of planes. better to choose what looks cool

#

off topic tho, we should let OP ask if they need to!

#

yeah so it kinda cools

#

just not in the onventional way that radiators actually do

whole mirage
#

it literally does not cool, thats what he is saying

#

the wiki page goes so far as to say it even acts as a heat sink which isnt actually useful in stock KSP either

#

it's just not as good as normal radiators

#

but don't use power

whole mirage
#

you guys are nuts, I never have any of these issues and never used the precooler

#

my planes work great

#

at the end of the day follow your heart but the data says you arent helping yourself
