The first engineering prototype of the 220 ton engine of heavy launch vehicle has entered production, signifying the completion of the research and development
Yesterday 06:28 PM (GMT+8)· EqualOceanRecently, the production of the first engineering prototype of the 220 ton afterburning circulating LH2/LOX engine of the heavy launch vehicle was completed in 11th Institute of the sixth Academy of China Aerospace Science and Technology Group (Beijing), marking the successful completion of the development of the engine in the in-depth stage. The 220 ton afterburning cycle LH2/LOX engine is the second stage core engine of China's heavy launch vehicle. Its performance index has reached the international advanced level, which can better meet the power requirements of China's future launch vehicles and major space missions. It is one of the important symbols of a space power.

220 ton thrust cryogenic engine YF-90 use in CZ-9 second stage.
480 ton thrust LOX/RP-1 engine YF-130 use in CZ-9 first stage and boosters.
The first and second stage engine of CZ-9 have completed or will complete half system test (without the noozle) by this year. The missing piece is the 25 ton thrust LH2/LOX YF-79 use in CZ-9 third stage, I still don't have much info.
Meanwhile the mature 125 ton thrust YF-100K engine will be used in 921.
