| 摘 要： | 本文研究了突变型进气畸变对某型发动机稳定性的影响。已有文献认为发射武器对发动机稳定性的影响主要是温度突升引起的。本文研究表明,发射武器时进口压力突变的影响不容忽视。当温度突升与压力突降组合作用时,增大压气机不稳定的可能性,这一结论也为试验所证实。

| Abstract: | The unsteady response of a compressor to abrupt change of inlet temperature has been calculated by numerical integration with the“actuator-volume”and the second order delay models.The calculated results are compared with flight test data favourably.The unsteady response of the compressor to abrupt change of inlet pressure(or combined with inlet temperature)has also been calculated in the same manner.The calculated results show that the effects of the abrupt inlet pressure on compressor stability cannot be ignored. |
