The invention discloses a complete machine environment compression component sensitivity coefficient acquisition method, and relates to the technical field of turbomachinery. According to the method, in the unsteady numerical simulation of the turbine engine, the gas compressor or the fan is destabilized through different surge modes, for example, the fan is destabilized by reducing the area of a nozzle, or the gas compressor is destabilized by supplementing gas through a main combustion chamber, so that the sensitive coefficients of the fan/gas compressor component in the whole machine environment are obtained respectively. 本发明的整机环境压缩部件敏感系数的获取方法，涉及叶轮机械技术领域。本发明可在涡轮发动机非定常数值模拟中，通过不同的逼喘方式分别使压气机或风扇失稳，如通过收小喷口面积使风扇失稳，或通过主燃烧室补气使压气机失稳，从而实现整机环境下风扇/压气机部件敏感系数的分别获取。
