%X Canard Rotor/Wing Aircraft(CRW)is a revolutionary high-speed rotorcraft that combines the speed and range of a fixed-wing aircraft with the flexibility of rotary-wing flight. In order to have an insight into aerodynamic interactions between the rotor/wing and fuselage of CRW in hover and low speed forward flight,a shaft-driven rotor/wing and scaled fuselage model were tested in an open circuit wind tunnel of Nanjing University of Aeronautics and Astronautics (NUAA), multiple six-component force and moment balance was used to measure the forces and moments of rotor/wing and fuselage respectively. Results show that in hover the fuselage normal force and pitching moment are relatively high due to the influence of rotor/wing downwash;and in low speed forward flight, the downwash have strong interaction on the normal force and pitching moment of fuselage due to the big dimension horizontal tail;the effects of downwash on the fuselage rolling and yawing moments are little and the influence on fuselage side force is considerable. These results can provide reference for flight dynamics research and control law development of CRW.
