The aerodynamic characteristics and mechanism of canard rotor/wing(CRW) aircraft during conversion from rotary to fixed-wing flight was numerically investigated. The variation of forces, moments and aerodynamic center with respect to rotor position are presented, the amplitude of lift, drag and aerodynamic center for this configuration in conversion can reach 10.7%, 3.7% and 0.6 m separately. The investigation shows that the cause of forces and moments variation is the asymmetry flow field in rotary plane and asymmetry interference between rotor and fuselage, the motion of aerodynamic center can be explained by the motion of rotor aerodynamic center and the variation of lift curve slope of rotor and horizontal tail.
