Because a pulse detonation engine has the advantages of high thermal cycle efficiency, high thrust-to-weight ratio, low fuel consumption, and a simple structure, it is ideal for application to high-performance propulsion devices. The countries that lead the world in the aerospace field attach great importance to it and have made relatively large strides in theories, experiments, and simulations. However, detonation is a difficult core process, and indirect detonation is usually used in practice. Indirect detonation means a deflagration to detonation transition (DDT) occurs, which concerns series of physical and chemistry changes.1 Shortening the DDT distance and increasing the frequency as much as possible while ensuring reliable detonation is a research challenge.2,3

准直流放电等离子体辅助起爆的研究

由于脉冲爆震发动机具有热循环效率高,推力重量比高,燃油消耗低以及结构简单的优点,因此非常适合应用于高性能推进装置。在航空航天领域处于世界领先地位的国家对此非常重视,并在理论,实验和模拟方面取得了较大进步。但是,引爆是一个困难的核心过程,在实践中通常使用间接引爆。间接爆震是指发生爆燃至爆震过渡(DDT),这涉及一系列的物理和化学变化。1在确保可靠爆炸的同时,尽可能缩短DDT距离并增加频率是一项研究挑战。2,3
