Abstract:A new model for rotor/wing aero-interaction in tilt-rotor aircraft is established by parametirc modeling method, which suits to flight dynamic analysis. The expression for calculating the boundary of rotor/wing aero-interaction area is derived using a simple and accurate method. The area of interaction is then calculated with analytical expression of numerical integration, as well as the velocity boundary of rotor/wing interaction. A wing tunnel test for tilt-rotor is conducted in different rotor collective pitch, wind velocity and nacelle angle. The comparison between test and calculation shows the effectiveness of this new model. © 2017, Press of Chinese Journal of Aeronautics. All right reserved.
