摘      要：The extension of flight envelope to high angles of attack has been a key requirement for modern *** combat aircrafts should be provided with super maneuver performance to improve operational *** this case,the incidence of aircraft could be very large,even reaching post stall *** aerodynamics show strong nonlinear and unsteady characteristics in the flight of high incidence,which are caused by complex flow structures such as attached flow separation and vortex burst[1].The unsteady aerodynamic modeling at high incidences is helpful to control law design and flight simulation which has great practical *** its progress over two decades,unsteady aerodynamic models can
