A proper engine cooling mechanism

[shagrat]

The interesting part was where someone said more or less "I don't have a f...ing clue how it works, but it FEELS not right!"

 

What do people expect as an answer to that? :huh:

The interesting part is not that i don't know how it works, the interesting part is that i've described something but labeled it wrong and nobody noticed

As you seem to miss the point many people tried to kindly explain to you, I'm gonna make my try the same way as you did.

 

I don't break a single engine in DCS, in any module, even using max power, Temps keep spot on. DCS is right, actually perfect. Prove I'm wrong.

 

 

S!

I'm not missing the point and i'm not blaming the ones who tried to help, i'm blaming me because i mixed two words up and after some keywords here, i realised my mistake

 

And i can prove that i was wrong due to my mistake but i can't prove you wrong or right because i can't see how the engine temps behave...

Good. Now, can we see your engine temps behaviour in order to comment on them?

 

 

Maybe instead of coming to wishlist you should ask for help first in whatever the dedicated module forum you want, about engine management. People usually is just as kind and helpful there as they tried here, even though there are like a zillion previous threads on the subject :smilewink:.

 

 

From my limited experience flying aircraft IRL (not warbirds for sure), engine temps can either rise or sink in a matter of seconds provided you don't follow the manual and procedures, and that's for a 100-200Hp GA aeroplane. We are tackling here with 1600-2000Hp beasts which best cooling system is airspeed rather than radiator's size itself. To me DCS modelling in temp behaviour where you can either break an engine in seconds or keep flying way beyond manual recommendations by a good handling and engine management is by far the best representation on how real aviation engines behave :thumbup:.

Well, as said, i mixed two words up and i'm not aware of a way to see the engine temp...

 

And no, I don't have any problems with the management but thanks for the input

But, isn't cooling issues a management problem? Just saying…

It is, but i never had issues with cooling

Hello Razor,

My 2cents, I haven't seen anyone mention one of the most important things and that is to open coolers fully before start, especially the allied planes, they will heat very quickly on the ground, and then the engine will blow shortly after takeoff. I'm not sure which aircraft you are talking about but that rule of thumb applies to any liquid cooled engine. the heat builds up before enough airflow is available to remove it, and you start "behind the 8 ball" so to speak, also they are somewhat sensitive to trim and flight attitude as it can disrupt airflow through the radiators. in a p-51 the auto rad shutters are painfully slow(even to this day in RL) and I have found after many, many toasted Merlins to leave the coolers open on manual at startup, (personally I do a complete run-up, mag and prop checks, so heat management is even more important) taxi, takeoff, then run 2250- 2700 and 30- 50 inHg airspeed over 220 then put rads in auto and watch them. I have found the coolant temp will remain fairly constant on auto, but the oil temp won't, so open it up a little till the oil temp starts to fall. I usually adjust both temps about 1 needle width below the bottom of the green then go to auto and maintain air speed and they will stay there for the most part. Most trouble in combat comes from the slow speed and reaction of the automatic system, so open them manually. also they are electric so a battery or generator failure will leave them stuck where they are at, most likely too far closed. Hope this helps

What I'd like to see is a proper engine cooling mechanism for WWII planes. Right now, It cools and heats up so fast, I don't think this is real...

 

Neither a water cooled GPU nor a Car could do what the cooling in DCS does...

 

Hopefully this is on the to-do list already

Well, it seems you do since you're here complaining about cooling :thumbup:.

I think you misunderstood this. Just that the temps are going up and down doesn't mean I have problems with the temps.

 

And I was "complaining" about the behaviour of the temps, not the engine management...

Ok, you have a point :thumbup: .

 

 

So, your whole concern is about they move up and down? You can believe me or not, but already told you aeroplane Temps behave like that even in GA, I can hardly believe warbids featuring engines in the thousands Hp are much different, and DCS represents that fairly well to my limited knowledge. You'd better be concerned when you are in a Cessna 172RG looking at CHT sink like mad even with cowl flaps closed while you descent for landing at a foggy airport with IFR FP but the actual ILS signal is broken :D. That sudden cool down can really crack your engine block, but I didn't complain to Cessna, or Lycoming, for such an unrealistic behaviour :smilewink: .

I thought the coolant temp gauge is the not existing engine temps gauge, that's why I said it can't be that the engine temps is going up and down... but everything is cleared now...
