| 摘 要： | 利用逆向式再生环形喷射装置，研究了高速喷射条件下液体的点火燃烧性能。实验研究发现:喷射条件下液体药的点火燃烧性能较整装式液体装药容易实现一致性，且燃速大幅度增加。同时研究了伴随再生喷射燃烧过程所出现的高频压力振荡，分析了高频压力振荡产生的原因。提出了液体药喷射条件下点火延迟度的概念，它可作为评价ＲＬＰＧ点火器工作性能的指标之一。利用喷射点火延迟度的概念，比较了液体药喷射点火延迟性能对于喷口面积、活塞质量、液体药粘度及液体药能量等参量变化的敏感性。

| Abstract: | A new type of LP regenerative injection simulator has been developed.AnnularLP jet ignition and burning properties in regenerative injection process are studied with this simu-lator and compared with bulk LP burning property. Pressure oscillations are observed to form inregenerative LP injection simulator and possible sources forming pressure oscillations are anal-ysed. In this paper,a new idea describing the jet ignition delay time in injection process is pro-posed and the trend of the jet ignition delay time with the variation of the parameter is described. |
