The YF-209 is a liquid cryogenic rocket engine burning liquid methane and liquid oxygen in a gas-generator cycle. The engine is designed for reusability and commercial use and is currently under development as of May 2024.
History
The YF-209 is designed for the commercial launch market in China with reusability in mind. It can be reused at least 30 times and can be restarted at least 3 times during the mission with deep throttle capabilities. The engine hot fire test was successfully completed in February 2023. Development has been prioritised in 2024 to meet the growing needs of the commercial launch market.
