Engine management when damaged

[Alkyan]

Hello everyone,

I have few questions concerning the procedure to apply when I'm in trouble. Both for the Bf 109 and the Yack.

 

Engine cooling system damaged :

If I got hit in the engine cooling system (white smoke leak), is there a way to avoid overheating/ extend the time or useable power before failure? I usually head home full throttle but maybe it's not the best (my reasoning is to use as much power from my engine before the cooling liquid/gaze runs out and the motors dies by overheating, no idea if it's optimum in the game or in real life).

 

Engine damaged :

From a hit or an emergency power abuse on the F4 (black smoke). Same question, is reducing throttle, rpm, mixture can allow you to extend the time before the engine stops?

 

Tank Fuel Leak

Nothing to do I guess, is there any negative effect (else than loosing your precious fuel and be a obvious target with your grey smoke)? 

 

Emergency time exceeded (F4)

Going back to continous mode fixes the problem in fews minutes (emergency time recovered). It seems to me that you can recover from this problem while using combat power or at least a combination of continuous/combat power. Keeping emergency power leads to engine damaged.

 

Crippled wings

Does bullets holes affect your drag by any way? Sometime when I shot a plane (or I get shot !), its wing only break few seconds later. I was wondering if it was real time strain calculation or just a pretty good looking feature. I mean does anyone ever experienced getting badly shot in the wing, survived but only for loosing this very wing few minutes later in a hard turn?

 

Fuel Tank on fire

Ctrl + E seems to be the appropriate fix.

 

 

That's a lot of questions, well, thanks for any advice !

Think they are a questions for the Dev,s there.

We don't know how much and how fast coolant leaks are as in reality they are random depending on size of hits I guessing.

 

Think the rule of thumb is to generally throttle back to save engine wear, but to be honest I'm not sure it actually has any effect.

The engine failure may simply be on a timer ??

 

As for damage drag....it should, but I'm not sure if this is modelled in the DM, I hope so.

I recently completed a ground attack mission in which I got bounced by a 109 on the way home. I survived the attack, trailing greenish gray smoke, and with my left wing shot up pretty badly.

 

It seems a lot of your questions can be answered in the affirmative.

 

I nursed the engine and made it about 70KM, to within sight, literally a mile, of my home base before the engine gave up the ghost. Additionally, the entire agonizing, exciting, flight back was spent fighting a machine that was waddling about the sky like a drunken pig because of the aerodynamic damage (I assume) to the left wing. It was an amazing, and exciting, and brilliantly fun experience. The more I fly this thing, the more forgiving I am willing to be of the minor flaws, because the immersion is better than any combat flight sim I've ever flown.

 

The only thing that would have made it better would to have been able to see more life below me, farmers, peasants in the fields and villages, a civilian audience to look up and see the smoking, wobbling, IL2 limp it's way home.

 

For the record I safely crash landed within walking distance of my home base. Walked back, enjoyed the warmly relieved welcome of my flight, whom I released for home as soon as it was clear I probably wasn't going to make it, and then accepted the mission success.

For the record, I love picking apart il2s flying away behind the action....doing all their dirty russian work... on the way home without a care in the world...ill show them....

This is all info that would be nice to know. However we do t have a manual. The rules that I would use with my car with a coolant leak or sever oil loss don't apply since this is a game.

That said, I firewall the throttle, climb,and hurry to my front lines. Since I can t land for shit in this game in ideal conditions, its a good excuse to land anywhere on my side of the front as I will get the same points either way.

When your engine is damaged, I have found that dropping your prop pitch and throttling down seems to help make your engine last longer.  I have no proof that this works but I do this and I am usually able to make it back to base.

Thanks you for your answers. I'm a bit disappointed that there isn't much information about this part of the game, however it means that there is interesting stuff to test out.

I hope not And I don't think so. As engine failure from overheating is modeled (closing radiators on yack for example), I would assume that cooling system failure just decreases the efficiency of the engine to cool down (more and more as the leak progresses?) ?

 

 

 

The more I fly this thing, the more forgiving I am willing to be of the minor flaws, because the immersion is better than any combat flight sim I've ever flown.

 

 

 

I agree, damage model can be very immersive, last night after jumping into a fighters fur ball in my 109, I reemerged with a missing part of my left stabilizer, a cooling system leak, multiple bullets hole on my wing. Suddently my left flap went off (however in the confusion I couldn't tell if it was from a recent bullet impact or because of strain on the damaged part). 

 

 

 

 The rules that I would use with my car with a coolant leak or sever oil loss don't apply since this is a game.
That said, I firewall the throttle, climb,and hurry to my front lines. 

 

 

Can I ask what is the rule to apply for coolant leak in a engine's car? To keep it going as longer as possible.

I've been trying that. It might be working (however if you throttled down too much, I had the feeling that it just kills the engine instantly). I could run some tests to check that tonight as the engine damaged status is easy to reach and reproduce with the 109 abusing emergency power.

For a Radiator leak, you can pour a whole bunch of pepper into the radiator, or a can of Bars Leak. Silver Duct tape or ASJ tape works for a little bit on a hose leak.

 

I wonder what other field repairs were done to limp an airplane along. I read once that they had open fires under the engines to keep them from freezing overnite. Or that the mechanics often worked outdoors, overnite in the sub zero temps. Ouch , now that's hardcore.

Indeed, not gonna help ingame !

 

For the record I tried to run some tests with the F4 :

- stay at ATA 1.4 until exceed emergy power

- Then go to ATA 1.35 until engine damage

- Then try different ATA to see if it changes the time to failure

 

Found out that time to failure is very random. At ATA 1.3 after engine damaged, failure occurs sometime after 30 sec or sometime after 4 minutes. So, hard to tell if throttling down help without doing A LOT of tests.
