为了评定涡扇发动机在稳态工作时的抗压力畸变能力 ,采用可调畸变度的发动机进口压力畸变模拟器 ,在发动机地面静止试车台上进行了不同进气畸变度下的整机抗畸变试验 ,试验中获取了发动机重要参数随不同畸变度的变化数据 ,并得到了发动机能稳定工作的最大进气畸变度范围
In order to evaluate the anti-pressure distortion ability of turbofan engine during steady-state operation, the whole machine anti-distortion test under different inlet air distortions was carried out on engine stationary test bench with adjustable distortion engine inlet pressure distortion simulator , The data of the variation of the important parameters of the engine with different degrees of distortion are obtained in the experiment, and the maximum range of the intake distortion of the engine can be obtained
