Design of capacitor charging ignition control system for solid rocket motor

摘要:

点火控制系统是某型发动机地面系统的重要组成部分，主要用于完成发动机的常态安全保护和点火控制任务。为优化系统性能，对电容充电原理和充电电路参数计算方法进行了研究，设计了电容充电式点火控制系统，解决了传统发动机点火电路应用大容量电池或电源模块来实现点火控制所带来的设备体积庞大、质量沉重，不便应用于便携式地面系统的问题，不仅可利用电容的瞬间放电能力准确实现对发动机的点火控制，还大大减少了点火电路的质量和体积，有效提高了系统的机动能力，大大扩展了系统的应用范围。

Abstract:

Ignition control system is an important part of the ground system of a certain type of engine, which is mainly used to complete the normal safety protection and ignition control tasks of the engine. In order to optimize the performance of the system, the principle of capacitor charging and charging circuit parameter calculation methods are studied, the capacitance charging type ignition control system were designed and solved the traditional engine ignition circuit application of large capacity batteries or power supply module to realize the ignition control equipment brought by the large volume, heavy quality, inconvenience is applied to portable ground system problem, not only can use capacitance instantaneous discharge ability accurate realization of engine ignition control, also greatly reduced the quality of the ignition circuit and volume, effectively improve the mobility of the system, greatly extend the application range of the system.
