Shulou(Shulou.com)11/24 Report--

CTOnews.com, November 10, according to the release of the sixth Institute of Aerospace Science and Technology Group, just five days after the first complete test run on November 5, the 80-ton reusable liquid oxygen methane engine developed by Beijing 11 Institute of the sixth Academy of China Aerospace Science and Technology Group was successfully tested for the second time.

CTOnews.com learned that this test is the second test on the basis of the success of the first machine test, the test time is 50s, the engine starts and shuts down according to the program, the working process is stable, the parameters are normal, and the working coordination and matching of the engine are further examined, and the working performance of each component is obtained.

The complete success of this test indicates that the engine has the conditions to change from the appearance to the original shape. In the follow-up, the engine performance and function test will be further carried out, and the reliability samples will be accumulated, which will lay an important technical foundation for the development and application of reusable launch vehicles.

According to reports, the engine has a ground thrust of 80 tons, a vacuum thrust of 90 tons, and a starting capacity of 3-4 times. It can be used as a power plant for a round trip transportation system, a reusable launch vehicle and a low-cost disposable launch vehicle. It has a wide application prospect.

In addition, the 80-ton liquid oxygen methane engine can not only achieve large-scale thrust regulation, autonomous state monitoring and fault diagnosis, but also quickly test without firing, and can fly again in 48 hours. The engine adopts full electronic control and has "intelligent brain", that is, health monitoring and fault diagnosis system, which can meet the needs of overall task reconstruction.
