TheYF-130 is a Chineserocket engine fueled byLOX andkerosene in an oxidizer-richstaged combustion cycle currently in development. It has been designed to reach around 500 tonnes of thrust and it will power the super heavyLong March 9 rocket.[3]
Chinese researchers completed a "half-system on full working condition" test of a YF-130 engine in March 2021, and expected to finish a whole-system test verification by the end of the year.[4] Full system test has been successfully completed on November 6, 2022.[5]
