Abstract

A pulsed detonation chamber (PDC) equipped with Hartmann–Sprenger resonators has been designed and tested for both Hydrogen/air and Hydrogen/Oxygen mixtures. A full-factorial experimental campaign employing four factors with four levels each has been carried out for both mixtures. Instantaneous static pressure has been measured at two locations on the exhaust pipe of the PDC, and the signal has been processed to extract the average and maximum cycle pressures and the operating frequency of the spark plug. The PDC has been shown to be able to reach sustained detonation cycles over a length below 200 mm, measured from the spark plug to the first pressure sensor. The optimal regimes for both air and Oxygen operation have been determined, and the influence of the four factors on the responses is discussed.

脉冲引爆发动机的压力增益实验分析

设计并测试了装有哈特曼-斯普伦格谐振器的脉冲爆轰室（PDC），可用于氢气/空气和氢气/氧气混合物。对这两种混合物进行了全因子实验，采用了四个因子，每个因子有四个等级。在 PDC 排气管的两个位置测量了瞬时静压，并对信号进行了处理，以提取平均和最大循环压力以及火花塞的工作频率。从火花塞到第一个压力传感器的测量结果表明，PDC 能够在低于 200 毫米的长度内达到持续的爆燃循环。已确定空气和氧气操作的最佳状态，并讨论了四个因素对响应的影响。
