【摘要】 重点研究稳态温度畸变对发动机稳定工作的影响。温度畸变分为周向温度畸变和径向温度畸变两种情况。温度略变将使发动机喘振裕度降低。情况严重时可使发动机工作不稳定，或发动机熄火，从而危及飞行安全。本文将给出进气道温度畸变和稳定性因子的确定方法，作为进气道／发动机匹配研究的基础。更多还原

【Abstract】 This paper is to emphatically study the influence of steady - state tem-perature distortion on the engine stable operation. The temperature distortion is classified astwo modes-the circumferential temperature distortion and radial temperature distortion. Theternperature distortion will cause the engine surge margin reduce and even the severe con-(Iilion will cause the engine operation unstable or flame - out to endanger the safetyflight. The paper is to provide the methods for determination of intake temperature distortionand stability factor as the basis for study of intake and engine compatibility.更多还原
