Abstract: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.
Keywords:flutter excitation system  fixed vane  excitation force  simplify model
