前言第二次世界大战后,随着世界航天工业的发展,固体火箭发动机从战术武器的推进器逐渐成为战略导弹的发动机及某些宇宙飞行器的动力装置是经过解决各种技术难点而逐步应用的。其中推力终止作为一种单项技术,在发动机的研制过程中也不断地发展和日益完善。目前,世界上多数弹道式导弹的末级固体火箭发动机推力终止是依靠装置于发动机前封 Preface After the Second World War, with the development of the world space industry, the solid rocket motor gradually became a strategic missile engine from the propeller of tactical weapons and the power plant of some space vehicles was gradually applied after solving various technical difficulties . Thrust termination as a single technology, in the engine development process also continue to develop and improve. At present, most of the world’s ballistic missile end-stage solid rocket engine thrust termination is based on the device installed in the engine front seal
