Planes radiator cooling faster at high alt

[Interceptor]

Altitude was a huge time modifier to cool down engines during WWII (at 30k+ temp is below zero, often -30F for exemple, and is still very low at 20k... ),
it would be nice to have that featured in a flight simulator like Aces High II...

The density is also much lower at high altitude so the heat capacity of the air is lower and therefore the heat transfer is lower and cooling capability lower.  Think of it this way: if you took it to the limit there would be no air at all and therefore no convective heat transfer at all.  You'd be left with radiative heat transfer only.

I second that^^^^

What 715 said. I vaguely remember it being a big issue for air cooled motors at high altitudes, its really hard to get rid of heat high up.

At 10000m the G2 engine(for this exemple) reached 217 degrees Fahrenheit after 10 minutes at max power,
At sea level it reached 239 degrees C after same test...

We dont have problem with overheating engines. Only thing that can be affected is WEP.
Remodeling the engines so that they can overheat and fail can be an interesting feature, not sure if people really want it dough. Part of the point with the game is that u dont need to be a pilot to fly, just jump in a plane and go.

Interesting, I can't read german, what was the manifold pressure at the two altitudes?

Does AH even model engine temp except for when coolant is lost?

It doesn't.
Neither plays it a role in normal operations, nor in WEP usage, which is strictly based on time.

If you wish faster at alt, you are actually wishing better radiator modelling in general...and that isn't a simple thing to implement.

Wouldn't the load on the engine (the work it's doing) be different in the dense air at sea level vs the thin air at 10000m?

thing you have to remember is that at altitude and in cruise confg, usually the power settings are reduced to 60 to 70% of rated power, so therefore, your engines or engine doesn't need cooling like it does below 10,000 feet.
One of the things you HAVE TO BE aware of is engine cooling to rapidly during descent, as that will ruin valves quickly.
AH remodeling for engine temps would be a waste of time! Most of the guys in here fly WAO 100% of the time, so you would have engine failure left and right and they wouldn't understand what was happening! (the pilots in this game)

I think if they added realistic engine modeling it would be really fun and interesting. LIke the engine getting overheated and quits. It will make folks talk less and put more concentration on flying.

I meant like talking a bunch of crap on 200.

should be easy to implement a faster cooling at X% throttle I guess.
