Method for designing output torque of aircraft nacelle lifting motor

A method for designing output torque of an aircraft nacelle lifting motor comprises the steps that aerodynamic loads and inertial loads of the aircraft nacelle under different load working conditions are equivalent to the gravity center of the aircraft nacelle, the maximum load is extracted to serve as the calculated load of the output torque of the lifting motor, and the load of a lead screw is calculated according to the calculated load and geometrical parameters of the aircraft nacelle; the output torque of the motor is calculated according to the lead screw load, the lead screw thread pitch, the friction angle, the friction coefficient between the lead screw and the support, the thread rise angle and the average diameter parameter of the thread. According to the method, the output torque of the aircraft pod lifting motor can be calculated more conveniently, quickly and accurately. 一种飞机吊舱升降电机输出转矩设计方法，将不同载荷工况下的飞机吊舱的气动载荷和惯性载荷，等效到飞机吊舱重心处，提取最大载荷作为升降电机输出转矩的计算载荷，由计算载荷和飞机吊舱的几何参数，计算出丝杠载荷，根据丝杠载荷和丝杠螺纹螺距、摩擦角、丝杠与支座在螺纹
