China’s moon-bound Long March 9 engine passes key test
China overcomes difficulties with Long March 9 engine
The new report details how the Beijing Astronautics Experiment Institute of Technology (BAEIT) announced that it had overcome technical difficulties with the first prototype of its YF-79 rocket engine, its thrust expansion cycle hydrogen-oxygen engine of 25 tons designed for the long Chinese March 9. rocket.
BAEIT is a unit of the state-owned China Aerospace Science and Technology Corporation (CASC), the country’s main space program contractor. He said he carried out three ground tests of the new hydrogen-oxygen engine on Friday, September 30, and also said he carried out 12 ignition tests in the space of a week.
“Our teams … have shortened testing cycles and increased testing capacity, and achieved back-to-back successes,” BAEIT said in a statement on its WeChat social media account, according to the South China Morning Post.
According to the South China Morning Post, the developers aim to make the YF-79 the most powerful rocket engine of its type. The most obvious point of comparison would be SpaceX’s next-generation Raptor engines that will propel its Starship rocket into orbit. The fully reusable Starship Launch System will use 39 raptor engines at launch, each delivering 230 tons of thrust at sea level.
A new space race
China’s Long March 9 rocket is a three-stage rocket with boosters. In its first stage, it will also use a 500-ton thrust supplement combustion cycle kerosene-oxygen engine under development, known as the YF-130.
