The first test in the initial sample stage was successful, and the development of the 80t reusable liquid oxygen methane engine of Aerospace Science and Technology Group is progressing smoothly.

Thanks to CTOnews.com netizen grass Luo Yuzi for the clue delivery! CTOnews.com, February 22, according to the announcement of the China Aerospace Science and Technology Group, the YF-209 test of an 80-ton reusable liquid oxygen methane engine in the sixth Institute of Aerospace Science and Technology Group has recently been carried out in the sixth Institute 101. the engine starts and shuts down according to the program, the working process is stable, the test data are complete, and the test is a complete success. In addition, CTOnews.com noted that the calibration test of the last stage engine of the long triple A series of rockets was also carried out on the same day.

This test is the first test of the engine from the scheme stage to the initial stage, which marks a new stage in the engineering development of 80-ton reusable liquid oxygen methane engine.

Aiming at the increasing power demand of commercial aerospace, this engine adopts the design concept and method of reuse, and has the characteristics of low cost, high reliability, convenient use and maintenance, excellent performance, non-toxic and non-pollution. Its ground thrust is 80 tons, vacuum thrust is 90 tons, and it has 3-4 ignition starting capabilities. it can be used as the power plant of space-to-earth round-trip transportation system, reusable launch vehicle and low-cost disposable launch vehicle. The first hot test run of the whole engine was carried out in November 2022 and achieved continuous success.
