No. 11 Institute of No. 6 Academy of China Aerospace Science and Technology Corporation (Beijing) Founded in 1958, Beijing Aerospace Propulsion Institute is the birthplace of China’s liquid rocket engines (LPRE)

With over 60 years of self-reliant and innovative development of China’s aerospace industry, the institute has developed many LPREs for strategic missiles and launch vehicles. The first generation Liquid Oxygen/Liquid Hydrogen (LOX/LH2) LPRE (YF-73) symbolized that China mastered the advanced super-cryogenic propulsion technologies and became one of leading countries in this field. The second generation LOX/LH2 LPRE (YF-75) keeps the successful launch rate record in China and is one of the four most famous upper stage engines in the world.

The YF-77 and YF-75D engines that achieved success in the first flight in 2016 raised China from the list of major player in space to the one of major power in space. The new generation LOX/LH2 LPRE is under development and breakthroughs have been achieved in key technologies. The light-weight, quick-response and high performance orbit and altitude control engines developed by the institute have accomplished many technological achievements and won intellectual property rights which are leading in the international arena. The space temperature control pumps and valves developed by the institute signed up for all previous flying assignments of manned spacecraft and target spacecraft, and are widely applied in space stations, lunar exploration project sand satellites. Hence, the institute has obtained advantages in four aerospace technological fields, i.e., the main propulsion stage engines, upper stage engines, orbit and altitude control engines and new energies and their applications.
