| 摘 要： | 再生式液体发射药火炮中液体药射流雾化性能是影响弹道性能稳定性的主要因素之一。本提出一种观测射流雾化形态的实验方法和相应的测试系统。利用所研制的测试系统，研究了受限空间中高速惰性液体和含能液体射流的扩展结构，环境反压，喷嘴形状和尺寸等各种参量对射流雾化形态的影响，分析了泰勒雾化理论和湍射流扩射理论对于ＲＬＰＧ的适用范围，在观测射流雾化性能的基础上，提出了进一步测定射流雾化规律的方法。

| Abstract: | This paper presents a new type of measuring system that can be used to visualize the liquid jet formation. With this system, in the confined space, the divergence structure of the inert and energetic liquid jet is investigated, and the effects of back pressure, nozzle diameter and nozzle geometry etc. on the jet formation are studied.Validation of the Taylor atomization theory and the turbulent jet spread theory for regenerative liquid propellant guns (RLPG) is analyzed. |
