Abstract

To improve the prediction of the rotor's off-axis aerodynamic response

the wake distortion effect of maneuvering rotor was studied with the introduction of time-accurate wake curvature parameter(KR) into the maneuvering rotor model.As compared with existing approaches

the computed results from this model are more close to the test data.Besides

a dynamic wake distortion model was constructed

while the necessity of incorporating the wake contraction effect was analyzed.The research results show that: the operating-state-dependent(KR) shall be applied to aerodynamic models in order to calculate accurately the rotor aerodynamic forces and moments

especially for off-axis response.
