Abstract

Abstract: In order to overcome the difficulty on initiation of combustion by continuous dielectric barrier discharge(DBD)based on AC drive in detonation tube,a plasma ignition device were designed successfully by frequency controlling,which can produce low temperature plasma periodically. The discharge parameter is adjustable. The single discharge time ranges from 0.1ms to 1000ms,and the variation of frequency is from 0.1Hz to 100Hz. The combustible mixture can be ignited and the detonation waves were observed in tube with single discharge time 0.5ms,by fixing a coaxial-type electrode into plasma ignition device. The research demonstrate that it is feasible to initiate detonation by low temperature plasma based on AC drive.

摘要： 为了克服交流驱动介质阻挡放电产生连续低温等离子体应用于脉冲爆震发动机点火的困难,通过频率控制,成功设计了按一定频率周期性地产生低温等离子体,放电参数可调,单次放电时间为0.1~1000ms,频率为0.1~100Hz。等离子体点火器采用同轴电极结构,单次放电时间0.5ms,实现了可燃混气点火,成功触发爆震,这些结果表明采用交流驱动低温等离子体点火触发爆震是可行的。
