1.前言单室双推力发动机是用一个燃烧室获得两级不同推力发动机。第一级具有较高工作压力,较大推力,短的工作时间,可以使导弹迅速地离开发射装置并很快地加速到所要求的飞行速度。第二级具有低的工作压力,小推力和较长的工作时间,可使导弹基本保持第一级末速度或再缓慢加速到所需速度。 1. Introduction Single-chamber dual-thrust engine is a combustion chamber to obtain two different thrust engines. The first stage has higher working pressure, greater thrust and shorter working hours, allowing the missile to quickly leave the launcher and quickly accelerate to the required flight speed. The second stage has a low working pressure, small thrust and long working hours, can make the missile basically maintain the first stage of the final speed or slow acceleration to the desired speed.
