Over-revving the FW 190 D9 1945
 

I cooked and wrecked my engine while diving a 190-D9 1945 beyond 700km/h. I thought the auto prop-pitch should have prevented this. Is this a bug or a feature?

Thanks,

Not sure whats modeled for IL2 1946 I would imagine its simplified and could be that its a Kommadogeraet/Bediengerät

The Jumo213A is not managed by the ATA setting.
the "Bediengerät" manages the engine settings, dependent on RPM, regardless of ATA , dependent on altitude airspeed etc.

Here's a Kommadogeraet overview image.

As for the diving problem ..................... you would have thought it was safe to reach those speeds.

The engine should not seize with the automatic control. It will prevent overreving.

Now, you did that at full throttle, or you took it at minimum?

If you overreved it with the throttle at minimum, something may be wrong.

In my experience I've only overreved when I was at maximum throttle in a high speed dive. If you throttle back it won't happen.

Mind you that stops my old favourite power dive at 110% MW50 engaged diving episodes that netted me several La-7s dead back in the early days of IL-2 Forgotten Battles. The La-7 used to be uber but it could never dive with a FW190D-9 running full out :D

That's the problem though, and that's how I burned the engine, running from a La-7. Sometimes you have to dive full out. Switching to manual pitch and setting to near 0 helps.

Hmmm, and since AI uses the engine very carefully, this explains why it is so easy to shoot down even a diving D9 in a La-7.

La-7 should not be able to get anywhere near a FW D-9

Especially in a dive............

For 11 years the La's have been "hotly debated" creatures.

This was online. He couldn't follow me and I did manage to get away, but my engine died a few seconds later. So yes, the La-7 can't dive as fast as the D-9, but unless the D-9 pilot is super careful about his engine management then he will cook his engine while doing so.

This seems like a bug to me, it's almost like the pitch control system doesn't know to reduce pitch at very high speeds. I'll submit in the team DT thread.

AI or human?

No I don't think it should either. If given time to accelerate it should be fine... even under the current conditions. Even before the max VNE, the La-7 begins to shed controls. The FW190D-9 can keep going... it's just the engine you need to worry about right now.

[QUOTE=IceFire;707711]AI or human?

Human La-7 vs AI 190D-9. AI maybe a little bit too careful with the engine. A human would still outdive the LA-7. It just needs a little abuse of the engine, just enough not to damage it. AI cant do that.

Of course, in reality it was easier to do it, La-7 wasnt that good even at medium altitudes.
