固体火箭发动机点火器传统工程设计的方法是应用经验公式估算点火药量,点火器结构设计依赖于设计人员的经验.本文依据数值方法给出了通用点火器设计方法,点火器流量估算方法.通过发动机压强上开段的峰值、达到峰值的时间来筛选方案,从而最终设计出点火器.文中还给出了实验结果.依据本文中提出的方法成功地进行了多种发动机的设计,表明工程应用性强. The traditional engineering design method of solid rocket motor igniter uses the empirical formula to estimate the ignition dose, and the igniter structure design relies on the designer’s experience.This paper gives a general igniter design method and a method for estimating the flow of igniter by numerical method. Engine pressure on the opening of the peak, the peak time to screen the program, and ultimately designed a lighter.The article also gives the experimental results.According to the method presented in this paper successfully carried out a variety of engine design, indicating that engineering applications Strong.
