Information

Longyun liquid oxygen methane engine completed a series of reliability hot test runs!

Recently, the Kyushu Yunjian Longyun liquid oxygen methane engine has completed a series of reliability hot test runs. Up to now, the Kyushu Yunjian test base has completed hundreds of engine hot tests.


In the first half of 2022, Kyushu Yunjian's 100-ton double-station liquid oxygen and methane thermal test bench can be said to be in full swing.

The first station is mainly for the reliability accumulation of Lingyun engine (LY-10) and the development of high-performance vacuum version (LY-10V), and the second station is dedicated to the thrust enhancement and reliability test of Longyun engine (LY-70). 

Under the strong guarantee of the 100-ton hot test base and the escort of the engine final assembly and test center, the Kyushu Yunjian Longyun engine was fully developed in the Year of the Tiger, and successively completed a stage of thrust enhancement (676kN), sequence optimization and system Simplified research, optimization of engine vibration environment, reliability of multiple starts, reliability of thrust change, and maintenance of serviceability and other series of reliability improvement assessment work have further consolidated the foundation for the development and development of domestic recoverable liquid oxygen methane rockets.
