超音速喷管 meaning in English

convergentdivergent nozzle
supersonic nozzle

In conclusion we note the following general items concerning flow in supersonic nozzles .
最后，我们归纳几个关于超音速喷管流动的一般原则。
The flow field of fadw is very complicated , especially in the free vortex jet zone . so the method is according to the ideal flow , including the design of the asymmetric supersonic laval nozzle and the diffuser
所以，本文所建立的fadw的基本设计方法是理想状态下的设计方法，其中主要包括非对称超音速喷管的设计和气动窗口扩压器的设计方法。
This paper studies the diffuser ' s influence on the fadw ' s running properties experimentally including the inner wall and outer wall of diffuser and the backpressure of the diffuser . to prevent the gas of fadw from leaking into the laser cavity because of the effect of layer and turbulence the leak - proof flakes are designed . first the method of the leak - proof flake design is studied and then its influence on the properties of fadw is studied experimentally
实验研究了扩压器对fadw工作性能的影响，提出了扩压器结构和超音速喷管相对布局参考数据；研究了气动窗口侧壁防漏片的结构对气动窗口性能的影响，并给出其工程设计方法；同时还研究了扩压器不同的背压对整个fadw作性能的影响，据此提出了扩压器与引射器结合的设计方案，从而为大压比、高性能的fadw的设计提供了进一步设计参考方法。
