摘要:
等离子体点火是发射药燃烧的一种新型点火方式，等离子体发生器性能会影响等离子体的输出效果。为了实现发射药高效的等离子体点火作用而研究等离子体发生器的输出性能。通过调整底喷式等离子体发生器内部关键参量,分析了发生器输出特性影响规律，优化了等离子体发生器内部结构参数,并在30 mm火炮中进行了试验。结果表明：等离子体发生器效率和输出电压及等离子体射流压强随毛细管孔径增加而下降，但随放电通道长度增加而增加；增加脉冲功率源的充电电压能够提高等离子体射流动能和压强峰值；聚乙烯（PE）和聚四氟乙烯（PTFE）两种材质对等离子体发生器输出特性影响不显著；经优选后的底喷式等离子体发生器能够在火炮装置中有效地点燃发射药。
Abstract:
Plasma ignition is a new ignition of gun propellant combustion, and performances of plasma generator have significant effect on the output of plasma. In order to achieve efficient plasma ignition of gun propellant, the output characteristics of bottomjet plasma generator were studied. The key internal structure of the plasma generator was adjusted to analyze the effect of these parameters on the outcome characteristics of plasma generator. The parameters were also optimized and validation experimentation was performed in a 30 mm cannon. The results show that the efficiency and the output voltage of plasma generator and the plasma jet pressure will decline when the aperture of capillary increases, but they will increase when the channels length increases. The plasma jet kinetic energy and pressure peak value will increase when the input voltage of pulse power supply increases. The difference between the effect of polythene (PE) and polytetrafluoroethene (PTFE) on the outcome characteristics of bottomjet plasma generator is indistinctive. Optimized bottomjet plasma generator has a favorable effect on gun propellant in the 30 mm cannon.
