摘要

为研究固体火箭发动机点火建压过程对药柱结构完整性的影响,设计了一套冷气增压系统。利用该系统对模拟火箭发动机进行冷气增压实验,得到了药柱所受的压力变化曲线。同时,利用计算机软件对冷增压过程进行流场仿真,对试验药柱进行数值仿真,将试验和仿真结果对比,吻合良好。结果显示,在药柱所受压力的压力峰到来时刻,药柱应变最大,说明固体火箭发动机在点火过程中产生的压力峰是影响装药结构完整性的重要原因。

Abstract

A set of cold gas pressurization testing system was designed to research the effect of solid rocket motor ignition process on the grain structural integrity. The system was used to carry out cold gas pressurization test of simulated rocket motor, the pressure variation curve of grain was obtained. Meanwhile, the computer software was used to simulate the flow field of the cold gas pressurization process, then the numerical simulation of the test column was carried out, and the results of the test are in good agreement with that of simulation by comparing. The results show that when the pressure peak of the grain is coming, the grain strain is the largest, which indicates that the pressure peak produced by the ignition of solid rocket motor is an important reason that affects the integrity of charge structure.

Key words： solid rocket motor; cold gas pressurization system; structural integrity of grain; flow field simulation; numerical simulation
