Abstract: The rolling airframe flying vehicle has a particular periodic unsteady aerodynamic feature. Its dynamic characteristics are more complicated, and unsteady correlativeness between the flow and rotation is more serious. The pitch damping derivative is as importent as the Magnus moment derivative. Based on the theoretical basis of aerodynamic modeling for flying vehicle, the present paper took into account the fact that the angular velocity of rolling airframe flying vehicles is non-zero, and reconstructed the aerodynamic mathematical expression of rolling airframe flying vehicles depending on the angular velocity of rolling as a basie flow state influence parameter. Based on the mature conventional dynamic derivative forced vibration methods, the periodic aerodynamic equivalent average pitching dynamic stability derivative, longitudinal wash-lagging derivative and rolling dynamic stability derivative were established using Fourier series to characterize the effect of rolling and the concept on periodic aerodynamic equivalent average of rolling airframe flying vehicles. Corresponding motion modes were designed for numerical calculations and wind tunnel tests.
