On January 4, the hydrogen-oxygen engine (YF-75) used in the final stage of the Long March-3A series rocket completed a 120-second ignition test run in Beijing.
The engine uses advanced liquid hydrogen and liquid oxygen as fuel, mainly providing power for the rocket's final stage.
Long March-7A rocket engine (YF-100) completed a 50-second ignition test in Xi'an on January 5
It is China's new generation of liquid rocket engines, using liquid oxygen kerosene as fuel
It is the main force of the new generation of launch vehicles such as Long March-5, Long March-6, Long March-7 and Long March-8.
We have just successfully completed the 50-second process qualification test run of the 120-ton high-thrust liquid oxygen kerosene engine.
This is also the first large-scale task undertaken by the 920 test launch platform of the 165 Research Institute in 2023.
After data interpretation, the engine performance meets the requirements.
