China’s new-generation launch vehicle LM-5 successfully completed its maiden launch in November 2016.Among the new technologies applied in the launch vehicle,four types of liquid rocket engines attracted extensive attention.These engines feature advanced concepts and technologies such as a staged combustion cycle and expander cycle.The engines are the results of hard effort of more than ten years,which is also an epitome of the development history of China’s aerospace industry.This paper gives a brief introduction to the technological schemes,main parameters,development process and application of the four types of engines that powered the new-generation launch vehicle.Finally,proposals for new liquid propulsion technology development in the future in China are presented. China’s new-generation launch vehicle LM-5 successfully completed its maiden launch in November 2016. Among the new technologies applied in the launch vehicle, four types of liquid rocket engines particularly extensive. These engines feature advanced concepts and technologies such as a staged combustion cycle and expander cycle. The engines are the results of hard effort of more than ten years, which is also an epitome of the development history of China’s aerospace industry. This paper gives a brief introduction to the technological schemes, main parameters, development process and application of the four types of engines that powered the new-generation launch vehicle. Signally, proposals for new liquid propulsion technology development in the future in China are presented.
