Milestone: China's 130-ton reused liquid oxygen kerosene engine continues to set a new record for ignition.

CTOnews.com, January 17, according to the official account of Xi'an Aerospace Power Research Institute, two consecutive start-up tests of 130T reused liquid oxygen kerosene supplementary combustion cycle engines have been a complete success in recent days.

CTOnews.com learned that Xi'an Aerospace Power Research Institute said that since breaking through two starting tests for the first time, the engine has completed four consecutive start tests in less than two months, and repeated ignition tests have created a new record for a high-thrust liquid oxygen kerosene engine.

According to reports, from the first breakthrough twice starting test run to the fourth round test run, the development team successfully broke through the twice starting plan and the taxiing period treatment technology. omni-directional and multi-level assessment of the engine twice starting time sequence, starting ignition life mapping, automatic engine cleaning technology and other projects, solid promotion of China's new generation of re-use carrier rocket world back and forth power plant development.

In addition, in order to assess the working reliability of the engine, the design team will continue to promote the assessment of the engine boundary envelope and the difference between heaven and earth to improve the adaptability of the engine working environment, and carry out the life test of each component. to achieve rapid iteration and improvement of product reliability; to explore the engine simplified treatment scheme and maintenance optimization technology to achieve the engine health management goal.
