摘要

采用优化设计结合数值模拟的方法对固体火箭发动机气体二次喷射复杂干扰喷管内流场进行了数值计算,研究了二次喷射流与主流相互耦合作用机制以及二次喷射推力矢量流动机理。通过对影响侧向控制力的喷射流物理参数、喷射孔位置、角度以及喷管几何参数的主效应和交互作用分析,找到了主因素及交互作用的影响规律。结合总结出的最大矢量角参数组合,开展优化方案的试验验证。

Abstract

The complex inner flow-field of secondary gas injection for solid rocket motor was numerically investigated by optimization design. The influences of different injection parameters on flow-field of secondary gas injection and the side force were analyzed and investigated. It gained the structures of shockwave series of secondary gas injection vector nozzle and complex main/secondary flow image by numerical simulation. By analyzing the main and alternation factors, the influence rule of the position of injection hole, the injection angle, the injection total pressure and total temperature on flow-field of secondary gas has been summarized. The optimization parameters are validated by test.

Key words： solid rocket engine; secondary gas injection; thrust vector; optimization design
