Study on Tilt Rotor Aircraft Modeling Method

Based on the aerodynamic structure design of a tilt rotor aircraft,the mathematical model of this aircraft was established.The aerodynamic force and torque equations of various aerodynamic planes were given with considering the rotor slipstreams.Blade element analysis theory was used to form the aerodynamic equations of rotor.This mathematical model could be used for design and simulation of the control system of tilt rotor aircraft.
