Abstract: The LM-5 is the large-scale cryogenic launch vehicle developed in China. It fills the gap of China's large-scale launch vehicle, greatly improves China's ability to enter space, and drives the overall progress of China's launch vehicle technology. In this paper, the breakthroughs and innovations of more than 240 key technologies of LM-5 has been comprehensively summarized, represented by new rocket configuration and overall optimization technologies, 5 m diameter rocket body structure design, manufacture and test technologies, high performance cryogenic rocket engine technologies, high reliability control and large capacity telemetry technologies, new test launch modes and launch support technologies. Moreover, this paper analyzes the gap between launch vehicle technology in China and the advanced level of foreign technology, and foresees the future development for the launch vehicle technology of China. Based upon this, the prospects of such key directions like the multi-specialty collaborative fine design, reuse of the rocket, intelligent flight and evaluation, advanced material and craft technology application, high performance rocket engine, intelligent unmanned test and launch technology are also put forward.

Key words: LM-5, rocket engine, structural design, materials and manufacturing process, highly reliable control, test launch and control
