Jumo213E Engine couldnt work well...
« on: April 07, 2021, 09:30:55 AM »

I m making mods to correct some op planes which have some wrong engine factor. Such as 2500+hp(2100 without MW) Ta152H.She must be 1750 without MW and 2050 with MW. But I have some problem with the engine.
Well,the original IL2s Ta152Hs engine(jumo213E) has a 3.2meters proper,though the real Ta152H has a 3.6meters proper.So I set it to 3.6,but problem just appeared.Engine feels like lost power(RPM drop badly at low airspeed especially taking off) and proper lost torque(acceleration and climb rate are super low).I tried to adjust the PropPhiMin and PropPhiMax.And RPM goes well now,but acceleration is still bad as well as the climb rate.
Thanks a lot and Best wishes

The IL-2 Flight Model has some severe limitations when it comes to prop diameter.
3.2 meters is about as far as it gets, anything above that you risk to see strange things happening, including loss of power, sudden wobbling in the air, loss of control when idling at high speed etc.
If I were you, I would keep the prop diameter at 3.2 meters and tinker with other values of the emd to get what you are trying to achieve.
