P-47D Turbine Overspeed Damage impossible. RPM link only works when increasing power.

[Cerdon]

Tested from qmb at 10,000 meter. Possibly only a qmb issue but I'm too lazy to climb for this test.

 

Realism settings only technochat and warmed engine

 

Turbine does not get damage from overspeed as high as 24,000 rpm for sustained periods at high altitude

&

RPM interconnect only functions when increasing throttle, rpm will stay at highest value when reducing throttle while interconnect is still on, using the rpm control then works, but only until it reaches throttle position where it then again locks.

 

P-47D-22 and D-28 with or without 150 octane, the turbine cannot be damaged from overspeed. With full 100% throttle and turbo, and 2550 rpm at 32,000 feet, the turbine reaches an overspeed of 24,000 rpm. Well beyond the 15 minute rated 22,000 rpm. Flying this way at 45" MP (according to technochat this is technically within continously power), for 15 minutes will result in the turbo being throttled back to 20,000 rpm without damage, from my understanding there was no automatic governor to prevent turbo overspeed generally or to prevent emergency power after the rated 15 minutes.

 

RPM interconnect is somewhat self explanatory, this quirk is not mentioned in the official manuals AFAIK, nor does it align with the 3d model which shows two prongs on either end of the rpm control which should lock to both ends of the throttle. In another sim which shall remain nameless, this interconnect works as I expected, so I belive this to be a bug.

It's not a bug. When connected with the throttle, was only meant to be moved forward with the throttle. It was set up this way to keep the engine from detonating (i.e., high boost and low rpm). It is mentioned in the official pilot's manuals btw. 🙂

OK did not know that, now I do now. As for turbine overspeed damage?

Just skimmed back over the manual and sure enough page 8 "...but the propeller control will remain at the farthest advanced position..."

Then the world wide bug is that I can run combat/WEP boost with lower rpm across all planes? So detonation is not part of the flight/engine model?

Yes, engine damage from turbine overspeed and detonation is not modeled.

Understood, is this a planned feature down the road or just an unrealism to contend with

Probably is going to remain as-is but we'll see.
