The aerodynamic technology of tilting rotorcraft is studied, including the research of dynamic wake and unsteady aerodynamic characteristics of rotor in transient state, the research of rotor / wing aerodynamic interference in transient state and the wind tunnel test of tilting rotorcraft model. The theoretical analysis method of the dynamic wake and unsteady aerodynamic characteristics of the rotor in the transient state and the aerodynamic characteristics of the rotor / wing are established. The effectiveness of the method is verified by comparing the published test data with the wind tunnel test results obtained in this study.
