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 reduce the ignition time of solid-state engine working for a short period of time, a transient model of engine ignition during short-time operation was established and the key factors influencing engine ignition time were determined. Combining theoretical analysis and experimental verification, the influence of combustion chamber charge structure on ignition time was analyzed. The results show that by reasonably designing the charge structure of the combustion chamber and shortening the combustion period of the propellant, the ignition time of the engine working for a short time can be effectively shortened.
