I'm quite certain you can overrev a Tempest in a dive, but I never actually tested it. I recall a few times going into a dive with everything full on + boost, and it sounded like the engine was going to explode any second. I yanked back PP and shut off boost and it mellowed out, but sometimes I'm left with a rough engine after that. I'll play with it tonight and see what happens. |

I doubt its modelled, but you can overrev a CSP...the governor just has to fail. |

CSP's ability to adjust RPM has a limit. ---------------- Flying online as nate85 "I can buy a scalpel, that doesn't make me a surgeon." - M_Gunz |

In real life sure, but is this limit modelled in IL-2? No one in sane mind ever turns when he has any other option. ~ DKoor |

Pretty sure. I do know that you can over-rev a 190 in a dive. ---------------- Flying online as nate85 "I can buy a scalpel, that doesn't make me a surgeon." - M_Gunz |

Yeah, in 190 you can, if you disengage auto pitch. Doubt you can however if you don't. No one in sane mind ever turns when he has any other option. ~ DKoor |

Correct, I forgot to mention manual mode. But IIRC the 190 in manual mode functions just like a CSP does it not?

You can over rev a CSP AND you can over boost the manifold pressure with a CSP. When you maneuver, you must adjust the manifold pressure to keep it within tolerance for the engine. Additionally, the CSP rpm is adjusted both at the cable, governor, and propeller itself. It is very common to adjust them at then come out on a different day to find your rpm/manifold relationship is not the same due to density altitude. Generally speaking, only on a day similar to the one the propeller/engine was adjusted will you find the performance stated in the manual. I once owned an airplane that required annual in June. Every winter, I would notice a 100-150rpm decrease at full throttle for example.

In RL no. The VDM propellers have two settings, Automatic and Emergency. In automatic, the VDM hydraulic electric propellers function as a CSP. In emergency, they function as an adjustable pitch. The pilot must adjust the pitch to reach the required rpm for the manifold pressure using "recipe" flying.

Yeah, I meant in0game  From http://en.wikipedia.org/wiki/Constant_speed_propeller
The above seems to me to be pretty much what we have ingame when the 190 operates on manual pitch. ---------------- Flying online as nate85 "I can buy a scalpel, that doesn't make me a surgeon." - M_Gunz |

It is not correctly modeled then in your game. The only "manual" on the FW-190 is the Emergency setting. This system is not designed for combat or cross country flight. It is an emergency setting so the pilot can safely land the aircraft for repairs. The manifold pressure is severly limited.

So, I tested the Tempest to see if I could overrev the engine, I started a dive from 16,000 feet, everything all the way up with Boost on, and it didn't overrev. It sounded like it would, but my ailerons came off before it could happen. Maybe a different plane might work for that test, but the Tempest has some great acceleration in a dive.
This is true, though, and this is modeled in the game, at least with the Tempest and Spitfire. It's happened quite a bit with both, but no other planes that I'm aware of. Many times I've nursed one of those two planes back to base with the PP and throttle set low just to keep the engine from running off. |

In RL, the governor does not have to fail. The blades just have to reach the stops. The propeller then begins driving the engine and your manifold pressure will begin to increase. If it increases too much, the engine will be damaged. All the best, Crumpp Our Museum glorifies no state, but strives to use these aircraft as a memorial for all lost in war.

We don't have shock-cooling from enormous dives, we don't have the prop gears tearing apart when given massive strain....
So much of what we don't have is because less than 20 frames per second is even less acceptable then getting exceptional circumstances aircraft behavior just so. When people take a plane out to see what it can do they really find what they can do with it. |

I've tried adjusting the supercharger in a P-47, and nothing happens. If you have the key mapped, and it doesn't seem to be working, is there another problem?
|

I believe the supercharger is automatic on the P-47.
