An experimental study was performed on an ethylene/oxygen/air pulse detonation engine to examine the effect of frequency and spark delay time on the thrust output and efficiency. Reactants were mixed in a stainless-steel combustion chamber at frequencies ranging from 1 to 40 Hz. Dynamic pressure measurements were recorded throughout the system over the testing interval to determine exhaust velocities. Efficiency was evaluated based on the experimental average frequency and the experimental average velocity. Results on experimental thrust, detonation frequency, and Chapman–Jouguet velocities were analyzed. It was observed that average thrust increased exponentially with the increase of detonation frequency. For a spark delay time of 2 ms, maximum efficiency and thrust were achieved for given frequencies. As spark delay time increased beyond 6 ms, testing became erratic, with pulses misfiring, and a decrease in efficiency and thrust was observed until no combustion occurred beyond a spark delay time of 8 ms.

在乙烯/氧气/空气脉冲爆震发动机上进行了一项实验研究，以检验频率和火花延迟时间对推力输出和效率的影响。将反应物在不锈钢燃烧室中以1至40 Hz的频率混合。在整个测试间隔内记录整个系统的动态压力测量值，以确定排气速度。根据实验平均频率和实验平均速度评估效率。分析了实验推力，爆震频率和查普曼-乔格特速度的结果。观察到平均推力随着爆震频率的增加而呈指数增加。对于2 ms的火花延迟时间，在给定频率下可获得最大效率和推力。随着火花延迟时间增加到超过6毫秒，
