Abstract:
The 25 tf LOX/LH2 expander cycle engine was developed for the three stage propulsion engine of Chinas heavy launch vehicle, which can also offer potential applications on various future launcher upper stages as well as orbital spacecrafts.The engine is a closed expander-cycle engine,and has the capabilities of high reliability, high specific impulse, variable thrust and multiple ignition.The engine has completed subsystem tests such as chamber, LH2 turbopump.The conditions for whole engine hot test have been met.
