摘要: 根据矩阵扰动分析理论,分析了发动机进口参数的扰动对发动机模型状态系数矩阵特征值的影响,并在此基础上进行了飞行包线区域划分,在应用这一方法得到的飞行区域内,发动机模型的结构参数摄动量可以在指定范围内变化,计算结果也表明该分区方法是正确的。Abstract: According to the matrix perturbance analysis theory,this paper analyzes the effects of engine inlet parameter perturbance on coefficient matrix eigenvalues of engine model. And based on the analysis,the engine envelope is divided into several areas. In these areas,the structure parameter perturbations of engine model are varied within a designated range. The calculated results indicate that the division method of flight envelope is proper.
