CTOnews.com news on February 23, according to the Beijing Aerospace Test Technology Research Institute (No. 101 Research Institute of China Aerospace Science and Technology Corporation), on February 23, the first 200-second long-range test run of an 80-ton liquid oxygen methane engine was successfully completed in the No. 3 unit of the institute.

The Beijing Aerospace Test Technology Research Institute said that this test verified the working reliability and thrust capability of the system and components under the rated operating conditions of the engine, obtained the engine performance parameters, optimized the engine shutdown sequence, and determined the technical status of the engine, indicating that the engine has taken a solid big step towards delivery flight.

During the commissioning period, the propellant supply system, the measurement and control system and the cooling and noise reduction system of the diversion trough worked stably, and each system was checked to be in good condition after the test. This test run is a complete success, and at the same time, it verifies the stability and reliability of the No. 3 test system of the institute, which lays a solid foundation for the successful completion of the high-density development and commissioning of 80-ton liquid oxygen methane engine in 2023. It provides a strong support for the rapid development of "eight years and nine engines" in the sixth Institute.

According to CTOnews.com 's previous report, the engine has entered the initial stage, with 80 tons of ground thrust and 90 tons of vacuum thrust, and has 3-4 ignition starting capabilities. it can be used as a power plant for space-to-earth round-trip transportation system, reusable launch vehicles and low-cost disposable launch vehicles. The first hot test run of the whole engine was carried out in November 2022 and achieved continuous success.
