中国航天科技集团六院1日披露,中国首台泵后摆火箭发动机首次试车已获得圆满成功,中国成为世界上第二个掌握泵后摆核心技术的国家。据介绍,此次试车的首台泵后摆发动机,是在已经进入工程应用阶段的120吨液氧煤油高压补燃发动机基础上,通过局部调整对液体火箭发动机泵后摆技术的有效验证。该发动机采用了全新研制的多种零部组件产品,尤其是多层波纹管柔性连接的高压摇摆软管,承受住了涡轮泵排出的高温高压富氧燃气多重考验,在试验过程中活动自如,结构可靠。中国航天科技集团六院,是中国唯一集运载火箭主动力系统,轨姿控动力系统及空间飞行器推进系统研究、设计、生产、试验为一体的专业研究院。该院院长刘志让说,泵后摆技术将摇摆装置后置,不
The 6th Institute of China Aerospace Science and Technology Group disclosed on the 1st that China has successfully completed its first test drive of a rocket motor with a rear pump. China has become the second country in the world to hold the core technology of pump backwashing. According to reports, the test of the first pump after the pendulum engine, has entered the project application stage of 120 tons of liquid oxygen kerosene high-pressure make-up engine, based on the local adjustment of the liquid rocket engine pump after the pendulum technology valid verification. The engine uses a variety of newly developed components of the components, especially the multi-layer corrugated pipe flexible connection of high-pressure swing hose to withstand the turbo pump exhaust high-temperature and high pressure oxygen-rich gas multiple tests in the test process freely, Reliable structure. Six homes of China Aerospace Science and Technology Group are the only research institutes in China that integrate research, design, production and test of the launch vehicle active power system, the orbital attitude control power system and the space vehicle propulsion system. Liu Zhirong, president of the hospital, said the post-pump technology will swing the device rear, no
