Reverse velocity blade
Dave,
Afraid that this beats me.
My simulator take reverse flow only 'marginally' into consideration, in that sense that it does 'statically (so to speak)' incorporate stall and reverse flow characteristics. This is already a small improvement over just ignoring it, as some of the math models that are published do (for instance first order harmonic models). Differences between ignoring it and incorporating it as in my model are small (I compaired both), because not only the region is small, but its lift contribution is even smaller.
Once this reverse flow region gets massive, my gut feeling is that aeroelastic models should be used, in order to get any reliable aerodynamic model. As I can't see how the h??l I could have that model work in realtime, I pass.
