摘要:阐述了小型固体火箭发动机点火装置单项点火试验的目的、作用，结合具体发动机点火装置研制，设计了单项点火试验容器。根据单项点火试验结果，对点火药药量、初始点火容积、喷管设计状态、点火方式、环境条件等因素对点火器点火性能的影响进行了分析，并对初始点火设计参数进行了调整。研究结果表明，基于单项点火试验所做的设计改进，解决了发动机研制初期遇到的点火延迟、低温点火失效等问题。
Abstract:The roles and aims of the single ignition test of the igniters, which used in small solid rocket motor, were introduced in this paper. Based on a lot of single ignition tests, the influence of mass of ignition powder, initial ignition volume, the design status of the nozzle closure and environmental conditions on the ignition characteristic of igniters were also analyzed. According to the single ignition tests results, some measures, such as changing the ignition manners, adjusting the ignition charge etc, had been adopted in the redesign of the igniter. The research indicated that the design modification had been utilized to solve the ignition delay, the ignition failure under low temperature etc ever occurred in the initial design completely.
