为了获得缩短短时间工作固体发动机点火时间的方法,建立了短时间工作发动机点火过程瞬态模型,确定了影响发动机点火时间的关键因素。采用理论分析和试验验证相结合的方法,分析了燃烧室装药结构对点火时间的影响。结果表明,通过合理设计燃烧室装药结构,缩短推进剂燃烧阶段的时间,可以有效缩短短时间工作发动机的点火时间。

In order to obtain the method for shortening the ignition time of short time working engine, a transient model for the ignition of a short time working engine was established, and the critical factors affecting engine ignition time were confirmed. The effect of combustion loading structure on igniting time was analysized by combining theoretical analysis with experimental verification. The results showed that through reasonable design of combustion chamber loading structure, the time of propellant combustion was shortened, which could effectively shorten the ignition time of short time working engine.
