4.11 - Engine: Overheat!

[Bolelas]

Mr Treetop64, is there any info about the radiator operations in the game? I mean, temperature limits, minimum, maximum, and for how long permitions, drags, speed limits in open(if any) etc?
I think we have some info about the engine RPM`s, not sure, (best cruise, best economy, best climb, max RPM...) But we dont have any info on the radiator operations. Do you know were i can get some? (not for real wwII aircraft, because i dont fly them, but for the 4.11 version planes. (if they are equal to real life wwII planes, better, we can extract from more sources...
If we should go for the gauges as you said (i agree) we must know limits.

Hope anyone can help, and on RPM´s also. Thanks.

Not sure, but the best way to start getting this sort of info is to find out what kind of engine a particular aircraft type has and do a google search on operating limits for that engine, or you can do a search on FAA Type Certificate Data Sheets. You may have to hunt around a bit on the FAA website, and I doubt if they have anything about old Klimovs or something equally esoteric, but but they do have tons of good information on many engines.

It helps to just get very proficient in two or three types of aircraft in the game, fly in them a lot, and just getting a feel for what works best. Just get in, fly her hard, and see what she can take - you're playing the role of test pilot. That's what I did and it worked.

As for radiator openings, in previous versions of the game you had to crank open the radiators all the way if you wanted to run hard for long periods, at the expense of creating more drag. Now in v4.11 that's not necessary any more. For example, in the LaGG-3 Series 4 I can firewall the throttle, set RPMs at 2300 (that will vary on it's own by a couple hundred RPM as I climb and dive. Usually when I'm making a sustained climb I'll manually adjust the RPM to 2500, then set it back to 2300 again when I level off), and adjust the mixture and supercharger as necessary per altitude. I only have to open the radiator two or three steps, and I can reliably run like that until the tanks are dry (or until I'm wounded and running home like a crying baby, or shot down, which are likely outcomes if flying the early LaGGs against an aggressive and competent foe!).

Hello!

We waited it so long and 4.11 released!

My favorite aircraft is Spitfire. I'm also trying to fly in ultra-hard realism with turned off HUD information like "Player killed", "Out of ammo", "Engine overheat!" (NoHudLog=1). In 4.10.1 and previous versions overheat on Spitfire engine started at 97-98 OIL TEMP gauge. And I even didn't understand for what there is RAD TEMP gauge - overheat started exactly at 97-98 OIL.

In 4.11 everything became harder. I can't understand when overheat starts. Sometimes it begins at one temp., and sometimes at another one. As I understand, warning sign "Overheat!" means that starts countdown to engine wreck that set random. How can I detect overheat without HUD? What algorythm of overheat on Spitfire?

[IvanK]

Kos Aim to keep Oil temp < 90deg C. Use lower RPM you can fly on most maps in the MKIX series +12/2800RPM all day without fear of any overheat.

[Koss]

Thanks! Спасибо! I flew Spitfire today with "Pilot's Notes for Spitfire MkV". Climbing at regament data (Boost, RPM) was exelent. I reached 10.000m without overheat. But combat mode data is impossible to reach. Overheat starts at 80-90 OIL TEMP, and 70-100 RAD TEMP (in last case is very difficult to detect overheat because arrow moves very slow). Combat mode (3000 RPM + Max Boost) results overheat in ~2,5min. What about this?

As stated elsewhere, the 'Overheat' message doesn't necessarly mean instant damage. If the 'rate of overheat' is low, it is possible to fly for a long time without damage. Another 2,5min without damage to reach the allowed 5min, is very easily possible. But if you instead recieve a damage after 2,5min, then something is wrong.

Given that some engines produced by the USSR and other countries were license-built versions of better known engines, the FAA info might still be helpful. For example, the Klimov M-103 was a license-built version of the Hispano-Suiza 12Ybrs.

I did some tests.
On the runway, + chocks + radiator closed
The put the engine at full power + Boost

Not is a rigorous test .

4.10.1
In general, for all aircraft, something like this.

2 to 3 minutes and you see - Engine overheat
6 to 9 minutes your engine are dead.


4.11
In general, for all aircraft, something like this.

50 seconds to 1 minute 20 s , and you see - Engine overheat
1 minute 20 s to 2 minutes 40 s you engine are dead.


" Engine dead "=
Something like this.


BF 109 engine Stops

FW 190 engine go to 1500 RPM and ..and down to 0

La 5 engine Stops

P51 engine on fire ... I be wonded

Spite Fire IXe , RPM variations exist but keep in 2900 - 3000
Then then exploded and I'm dead.

I love having to manage the engine closely and often, it is a great feather in the sims cap.

It is not a new one though, does anyone else remember that in an early patch of FB the 109E was given manual pitch only and it had to be constantly manipulated during a dogfight?

Those who have flown the Russian aircraft in this sim for years always had to deal with mixture and switching supercharger speeds. I remember many dogfights vs. Yaks in years past and watching them go rich, smoke black and lose power at the top of a loop when inexperience pilots did not keep on top of their game.

For many years I flew the FW190A and D models mostly on 0% pitch, and just switched to auto-pitch when a fight came along, they ran cool and economically that way, and likewise the prop pitch on many allied aircraft could be set to keep them cooler, it was just not as realistic or pronounced as it is now.

Juggling radiator, prop pitch, mixture and superchargers has always been the job of the hard-settings pilot in IL2.....

I'm really enjoying the new engine overheat.

That and the new AI are the 2 most game changing things to have come to il2 for an age, and both most welcome.
