China News Service, Xi'an, November 26 (Zhang Yichen, Yang Yingqi) The reporter learned from the Sixth Academy of China Aerospace Science and Technology Corporation (hereinafter referred to as: the Sixth Academy of Aerospace Science and Technology) on the 26th that the 130-ton reusable liquid oxygen kerosene supplementary combustion independently developed by the Academy The first two-start test run of the cycle engine was a complete success.
It is understood that this type of engine is a space-to-earth shuttle power plant aimed at the reuse of China's new generation of launch vehicles. It has the characteristics of high comprehensive performance, strong expansion capability, and high reliability. The demand for space activities such as the operation of China's space station will enhance China's large-scale, low-cost access to space capabilities.

It is reported that on the basis of fully inheriting the development technology of series models, the development team of the Sixth Academy of Aerospace Science and Technology completed the program design to the whole process demonstration and verification in less than a year, realizing the generalization and integration of this series of engines Integrate with digital intelligence technology.
In addition, some engine components adopt new technologies such as 3D printing, automatic welding, and intelligent assembly, and have made breakthroughs in key technologies such as repeated use of high-thrust engines, high-pressure afterburning, double ignition, and continuously variable thrust, which is a major milestone. .
The test run was carried out on the 502 "meritorious test bench" of aerospace liquid power.
The Sixth Academy of Aerospace Science and Technology stated that generations of liquid power people have continued to struggle, adapt to application needs in a timely manner, and continuously improve their capabilities, providing important support for the development and finalization of engines such as manned spaceflight, Beidou navigation, and lunar and fire detection.
