Beijing Aerospace Power Research Institute: the second semi-system test of high-thrust supplementary combustion cycle hydrogen-oxygen engine was a complete success.

CTOnews.com, February 3, according to the Beijing Aerospace Power Research Institute, on February 2, 2023, the high-thrust supplementary combustion cycle hydrogen-oxygen engine developed by the Beijing Aerospace Power Research Institute carried out the second semi-system test in Yungang, Beijing, and the test was a complete success.

On the basis of the first semi-system test, this test is equipped with all the core components to further study the work coordination, structural reliability and engine starting and shutdown procedure of the supplementary combustion cycle engine, which lays a more solid technical foundation for the follow-up test of the whole engine. CTOnews.com learned that in the test, the engine started normally according to the program, the working process was smooth, the parameters were normal, and the program shut down. The experiment completely achieved the desired purpose.

This test is another milestone in the development of high-thrust supplementary combustion cycle hydrogen-oxygen engine, and further verifies the design, manufacture and test scheme of high-thrust supplementary combustion cycle hydrogen-oxygen engine. It marks a major breakthrough in the technology of high-thrust supplementary combustion cycle hydrogen-oxygen engine in China, and lays an important foundation for the development of heavy launch vehicle. In the follow-up, the research and development team will speed up the experimental research on the whole machine, implement the planning goal of "eight years and nine aircraft" with practical actions, and contribute to the development of China's aerospace power.
