Thanks to CTOnews.com netizen Jiang Feng for the clue delivery! CTOnews.com, November 26, according to the release of the sixth Academy of China Aerospace Science and Technology Corporation, the first two start-up tests of its 130T reused liquid oxygen kerosene supplementary combustion cycle engine have been a complete success.

CTOnews.com learned that the engine is a world-to-earth power plant built for the reuse of China's new generation of carrier rockets, and has the characteristics of high comprehensive performance, strong expansion ability, and high reliability. The engine will effectively support the development of China's reusable space launch vehicles, meet the needs of space activities such as the operation of China's space stations, and enhance China's large-scale, low-cost space entry and exit capability.

It is reported that on the basis of fully inheriting the development technology of a series of models, the research team of the sixth Aerospace Institute completed the demonstration and verification from the scheme design to the whole process in less than a year, and realized the technical integration of generalization, integration and digital intelligence of this series of engines. In addition, some parts of the engine adopt new process technologies such as 3D printing, automatic welding and intelligent assembly, and have made breakthroughs in the repeated use of core key technologies such as high-pressure secondary ignition and continuous variable thrust of high-thrust engines. is of great milestone significance.

In order to realize the vertical take-off and landing reuse of the launch vehicle, the design team tailored a number of key technologies with fully independent intellectual property rights for the engine:

Multiple ignition

Compact structure and layout

Reusable

This test run is carried out in 502 aerospace hydrodynamic "meritorious service test-bed", which is the 24th type 756th test-run task undertaken by the test-bed in the past 52 years. The continuous struggle of liquid-powered people will provide important support for the development and finalization of engines such as manned spaceflight, Beidou navigation, lunar exploration and fire detection.
