为考核导弹与冲压发动机匹配性而建立的弹发匹配验证试验系统,采用了暂冲式气源和渐近式启动的航空发动机主燃烧室作为加热器,常规方式下启动较慢。为使来流能够在当量时间(即累积消耗空气流量除以最大工况流量,以下同)10s内启动成功,对影响来流快速启动的各个因素进行分析,并逐项进行优化设计。通过试验证明,采取的措施有效,来流可以实现快速启动。

We can use missile-motor matching validate test system to evaluate matching of missile and ramjet motor. It uses short-lived air and gradual start-up main firebox of aeroengine as heater; it starts slowly under the conventional way. In order to start-up in ten seconds, the factors of affecting quickly start-up is analyzed, and every item is optimized. By test, it can prove those optimizations methods are available, coming flow can quickly start-up.
