The YF-50t is a Chinese cryogenic rocket engine being developed to power the upper stages of the Long March 5 family of launch vehicles. It is an indigenous development based on Chinese experience with the YF-73 and YF-75 upper stage engines. It is gimballed in two axes. Hydrogen bled from the engine is used to pressurize the oxygen tank, and helium is used to pressurize the hydrogen tank.[1]
