"Longyun" liquid oxygen methane engine completes long-distance thermal test

Recently, Kyushu Yunjian's "Longyun" liquid oxygen methane engine completed the long-term thermal test run under rated conditions at the 2# station of the Bengbu test base. In this hot test, the engine systems were working normally, and the engine performance indicators were in line with expectations. The hot test was a complete success.


Two major breakthroughs were made in this test drive:

01 New station

The hot test was carried out in the 2# station of the Yunjian Bengbu test base in Kyushu. This station is a 100-ton special station. Before this, the 2# station has successfully passed the test bed acceptance test, and the 100-ton duplex station The bit test capability will be fully developed in 2022 to fully guarantee the delivery of the two types of engines.

02 Thrust boost

After rapid iteration, the "Longyun" engine in this hot test has a rated thrust of 677kN and a ground specific impulse of 291s. It is the liquid oxygen methane engine with the largest known thrust in China, and it is also the only comprehensive breakthrough in rocket recovery and reuse technology in China. high-thrust liquid oxygen methane engine.
