Thanks to CTOnews.com netizens vegetable, grass Luo Yuzi's clues delivery! CTOnews.com, November 16, according to CCTV news, on the morning of November 16, the 25-ton closed expansion cycle hydrogen-oxygen engine completed the full system test run. The test started according to the scheduled procedure, the engine worked normally, the test data were complete, and the test was a complete success. At present, this engine is a closed expansion cycle hydrogen-oxygen engine with the largest thrust in the world. Its performance has been significantly improved and has reached the advanced level in the world. It will support the development process of China's heavy launch vehicle.

The test-bed that undertakes this test is the "Aerospace liquid Power merit Test-bed", which undertakes the development and breeding of multi-type liquid rocket engines. Since the first test at the beginning of 1960, according to the needs of model development, the test-bed has been modified many times, the technical capability system of liquid rocket engine test has been continuously improved, and the test level has been gradually improved to meet the needs of multi-type engine development. it has made great achievements in the history of aerospace liquid power development in China. The success of this experiment marks the expansion of the test spectrum of the meritorious service test-bed.

In September this year, the first thermal test of the 25-ton closed-cycle hydrogen-oxygen engine of the sixth Research Institute of China Aerospace Science and Industry Corporation was a complete success.

According to the Beijing Aerospace Power Research Institute, the thrust of the 25-ton hydrogen-oxygen engine is three times that of the upper-class hydrogen-oxygen engine in service in China, and its specific impulse and other performance indicators have significantly improved, reaching the advanced level in the world. It is a landmark product for China to move from a space power to a space power.

CTOnews.com learned that the engine adopts a closed expansion cycle scheme, has the advantages of high performance and high reliability, has the ability of multiple starts and a wide range of variable thrust regulation, is the preferred power for the upper stage of large and heavy carrier rockets and space vehicles, and can be used for complex space missions such as manned lunar landings, manned fire landings, and deep space exploration.
