摘要

模拟脉冲爆震发动机(PDE)间歇式工作方式

研究了不同进气道型式在关闭和开放情况下的阻力特性。结果表明

PDE阻力大小与来流速度的平方成正比。在进气道开放情况下

研究了不同进气道型式对爆震管内气流速度的影响

从而在选取和设计进气道时能够综合考虑阻力和进气量两方面的因素。并研究了爆震管在安装气动阀和扰流片条件下PDE的阻力

有助于认识各部件对PDE阻力的影响和贡献。研究结果对减小PDE阻力

设计和选取合理的进气道、气动阀以及扰流片具有一定的参考意义。

Abstract

The resistance characteristics were investigated for various inlet types in opening or closing mode to simulate the periodic working of Pulse Detonation Engine (PDE).The result shows that PDE resistance is in proportion to the square of flying velocity.For the inlet opening mode

the influences of different inlet types on the flow rate of detonation tube were studied.Consequently

during selecting and designing the inlet

effects of PDE inlet type on both resistance of PDE and flow rate in detonation tube can be considered.PDE resistance was also investigated when aerovalve and spoiler were installed.It is helpful to recognize how different part of PDE effects on and contributes to resistance.These results are also important to aerovalve and spoiler design.
