In order to accurately predict the maneuvering characteristics of the aircraft, dynamic aerodynamics was then studied. Dynamic unstructured mesh technology in computational fluid dynamics was used to build forced oscillation method which could simulate the periodic pitching motion of the aircraft. The NACA 0012 airfoil was selected as the research object to validate the method. The static and dynamic derivatives winged missile Finner under different Mach numbers were computed and the dynamic aerodynamic hysteresis characteristics under different reduced frequencies were analyzed. The results showed that the method in the paper could effectively and correctly simulate the dynamic aerodynamic characteristics of winged missile under different Mach numbers and it could find wide application in engineering.
