本文介绍一种不改变发动机推力方向,使导弹在保险机构动作后相当于由一级推力变为二级推力,因而使发动机继续工作的保险装置的设计思想和工作原理。计算了火箭发动机防内压超载而设置的保险机构动作的压力选择范围。讨论了在战术导弹上设置安全保险装置的理由。还分析了在发动机上安装保险机构给导弹的生产,装配及试验过程中带来的问题。
This paper presents a design concept and working principle of the safety device that does not change the thrust direction of the engine and makes the missile equivalent to the second-level thrust from the first-level thrust after the insurance agency moves, so that the engine continues to work. The pressure range of the insurance agency’s action set by rocket engine anti-internal pressure overload was calculated. Discusses the rationale for setting up safety guards on tactical missiles. It also analyzes the problems that arise in the production, assembly and testing of missiles by installing insurance mechanisms on the engines.
