- YF-73 abstract "The YF-73 is China's first successful, cryogenic, gimballed engine, using liquid hydrogen fuel and liquid oxygen oxidizer. It was used on the Long March 3 H8 third stage. It run on the simple gas generator cycle and had a thrust of 44.15 kilonewtons (9,930 lbf). It had four hinge mounted nozzles that gimbaledeach on one axis to supply thrust vector control and was restart capable. It used cavitating flow venturis to regulate propellant flows. The gas generator also incorporates dual heat exchanger that heat hydrogen gas and helium supplied from separate system to pressurize the hydrogen and oxygen tanks. The engines was relatively underpowered for its task and the start up and restart procedures were unreliable. Thus, it was quickly replaced by the YF-75.".
