Mainly studies and establishes the helicopter flight performance simulation model. Based on the helicopter kinematics and kinematics differential equations, it mainly solves the aerodynamic and moment models acting on the helicopter components. The aerodynamic simulation model of the rotor and tail rotor is established. Waving movement was analyzed and studied, as well as the simulation model of horizontal tail, vertical tail, fuselage and gravity. Finally, through the analysis and study of each flight performance index and its verification principle and method, the static performance index is verified and the dynamic performance index is verified by the scalar index method.
