Hurricane engine lock at 10,000 ft

[santaclaus99]

Playing the Stalingrad career under realistic settings I was flying at around 10,000 ft on my flight lead, there was a loud clunk and my engine stopped with the prop freezing. I hadn't received any damage and my oil and water temps were normal. I had the radiator open at 50%, never overheated the engine and everything else was normal. After the engine seized I was close enough to an allied AF to make a dead stick landing and after stopping, I tried to restart the engine. The process proceeded to the point of hearing the whine of the startup but the engine would not restart. The HUD gave no indication of a damaged engine. Does anyone know what happened?

Maybe exhausted the time on certain engine setting (e.g. WEP or combat)?

That can kill your engine without warning or announcement when the techno chat is not working.

At least that does happen to me from time to time, as there are no indication from your engines that they are about to fail

[santaclaus99]

I don't think so. I was keeping my boost pressure under the red line the entire time.

if you didnt run out of fuel, then i bet its engine timers, rpm comes to play also, and usealy if engine just stops without any info is engine timer run out, and game dont tell you when safe time run out if you dont have instrument panel option on.

Can you please explain what is engine timers. Never heard this. Does it mean that you can have the engin quit before you run out of fuel, just because you flew more than a certain time. That's totally unrealistic right?

[CountZero]

its game thing that makes sure on some airplanes its engine is on its last 1-3-5min of full power life. So they pick best posible conditions for airframe of airplane, but for engines they decided that every airplane will have engine that is so broken out by the time you take it that if you go just few seconds abow recomended safe time it will blow up, and on top of having airplanes with wors condition engines when it comes to maintanance you as player dont even get corect info when game wonts you to not brake engine, you just have to feel it unlike every other 500+ messages you get about state of airplane, most of them are not ending your flight randomly, and most you dont need as you can see data from cockpits or suroundings, but engine timers, god forbid you get corect info about that...

That is not exactly true. I think there is some kind of probability about your engine stopping after you exceed the timer. So, if you take engine settings below the nominal values before the timer, then you will surely not have damage (and it seems that some kind of a counter-timer starts that reduces amount in timer, if you will go over the limit again later on). If you exceed the timer, then I think there is some kind of probability check, so you could destroy your engine in a few seconds or possibly carry on for a minute or two, before engine gets destroyed. 

Safest way to keep your engine alive is to keep it under nominal settings and exceed these only when really in need and then make sure not to exceed the timers.

Talking about Hurricane, these are the timers:

Engine modes:
Max Cruising power (unlimited time): 2650 RPM, boost +7
Climb power (up to 1 hour): 2850 RPM, boost +9
Combat power (up to 5 minutes): 3000 RPM, boost +12/+14 (low gear/hi gear)

Flak?

Wouldn't the engine be overheating if the timer had been overrun? I mean, you should've seen a high radiator and oil temp before engine suddenly dying? I don't fly with technochat, so use only instruments to have an idea about how hard I'm pushing the bird.

 

Have random engine failures been modeled?

No. There are no clues whatsoever from the engine that you exhausted a certain time limit. It just  damaged/dead from onemoment to the other. 

[R33GZ]

Can't say I've ever noticed that. Usually I've exhausted the oil supply, run the engine too hot or had battle damage that I other wise didn't notice... usually resulting in either a lack of water or oil

By any chance were you really flogging it to keep up with your AI leader?

Initially I was after takeoff. After takeoff for around a couple minutes I was around 9-10 boost with the radiator closed and after I started to get hot, but not overheated, I opened the radiator and had to increase boost a little to keep up. After reaching cruising altitude was able to stay in formation at 8+ boost and with a radiator half open for normal cooling. I flew like that for 15 minutes or so without increasing boost and on normal temps on the way to target before the engine suddenly seized. A previous post said 7+ boost is normal for cruising so maybe that was the problem? The red line on the gauge looks to be at 9+ but maybe that doesn't matter.
