某固体火箭发动机点火启动过程的仿真研究

Simulation and analysis of the solid rocket motor’s igniting process

摘要:

对固体火箭发动机点火启动过程进行了内弹道仿真,讨论了点火药量、点火药颗粒度以及防潮堵盖吹脱压力对点火启动过程的影响,尤其是对点火启动时间和初始压强峰的影响,并提出了对点火启动过程各参数选取的建议。

Abstract:

This paper analyzes the affect to the igniting process of the mass and the grainiess of ignition powder and the pressure that can destroy the lid which prevents the damp from the propellant, especially the affect to time of ignition and initial pressure peak by simulating the internal ballistic of the solid rocket motor’s igniting process. Some advices to the selection of the parameters in igniting process are put forward.
