- 摘要:
- 从理论上分析了燃烧室压力振荡引起喷嘴出口流量振荡的振荡传递。推导了振 荡传递过程的传递函数。讨论带有各种喷嘴的燃烧室的动态特性，计算了燃烧室压强、喷嘴 压降、喷嘴类型及结构尺寸对燃烧室压力振荡引起喷嘴出口流量振荡的影响，得到了喷嘴在 此传递过程中的影响规律。
- Abstract:
- The propagation process of injector exit flow oscillation induced by combustion chamber pressure oscillation was theoretically researched，and the transfer function of the oscillation was also deduced．The dynamic characteristic of combustion chamber linked with various injectors was discussed．The influence of combustion chamber pressure，injector pressure drop，injector type and configuration on pressure oscillation propagation process was calculated，the influence rule of injector on propagation process was gained．
