摘要/Abstract

摘要： 把固体火箭发动机柔性喷管的摆动机构看作为一个结构体系，在枚举了其主要失效模式后，采用结构体系可靠性分析的二阶窄边界法，对柔性喷管的摆动机构进行了结构可靠性分析，得到了柔性喷管摆动机构结构可靠度的基本公式。

Abstract: The slew mechanism of flexible nozzle of solid rocket motor (SRM) is considered as a structural system, and the main structural failure modes of the slew mechanism are presented. Based on the Narrow Bounds Method of structural system reliability, the structural reliability formulations of the slew mechanism are obtained.

Key words: Solid propellant rocket engine;Movable nozzle;Structural reliability
