The Academy of Aerospace Propulsion Technology reportedly is a research and development center for liquid engines and inertial guidance systems for launch vehicles. [2] This academy was originally established in the late 1960s as a Third-Line facility. [3]

The academy’s more recent products include the YF-77 and YF-100 rocket engines. The YF-77 uses liquid hydrogen (LH2) as fuel and liquid oxygen (LOX) as oxidizer, and the YF-100 uses Kerosene as fuel and liquid oxygen (LOX) as oxidizer. These rocket engines power the Changzheng-5 (Long March-5), China’s next-generation heavy-lift launch vehicle for commercial satellites and space station modules. [4]

Important departments, institutes and factories include the following: [5]
•    11th Research Institute, Xian Aerospace Propulsion Institute;
•    101 Research Institute, Beijing Institute of Aerospace Testing Technology;
•    165 Research Institute;
•    801st Research Institute, Shanghai Institute of Space Propulsion;
•    7103 Factory;
•    7414 Factory, Xian Hanxing Factory; and
•    Xian Aerospace Measurement and Test Center.
