摘　　要：通过基于双时间方法求解非定常欧拉方程得到固定小翼激励力源数据,分析了这种新型颤振激励系统工作原理,对固定小翼新型颤振激励系统工作原理的分析,建立了激励力简化计算模型。可实现M=0.3～0.5飞机稳定飞行状态下激励力载荷计算,大大简化了计算过程,精度足够满足工程分析,可满足试飞数据实时处理的需要。The simple model of the excitation force of the new Fixed Vane Flutter Excitation System was established based on the result data obtained by the dual-time method for Euler equations, and upon the analysis of the excitation system operational principle. By this model, the excitation force can be calculated easily when an aircraft modified with the excitation system is in steady flight, and mach is from 0.3 to 0.5 The calculation precision is enough for engineering application and satisfies the flight test data real-time analysis requirements.
