摘要: A hybrid Navier-Stokes/free-wake solver has been employed to investigate the performance of a rotor equipped with Gurney flap in steady level flight and descent. scaled model BO-105 was studied. The calculations were coupled comprehensive analysis properly account for effects elastic deformations on aerodynamic loads trim. Fixed dynamically deployed flaps considered. In forward flight, it found that chosen azimuthal deployment schedule may reduce peak-to-peak variations hub loads, potentially reducing vibrations. descent fixed decreased rate needed maintain autorotation.
