Abstract:
Reusability is an important way to reduce the cost of space launch,and is an important direction for the future development of liquid rocket engine.The development tendency of reusable liquid rocket engine is described in this paper.The power systems are discussed according to the demands of engine functions of the reusable launch vehicle (RLV).The combination of LOX/Kerosene and LOX/Methane propellants as well as their different cycle modes are compared.It is found according to the comparison that all these mentioned above can meet the needs of RLV.The key technologies of the reusable engine were studied,which indicates that the assessment technologies for thermal fatigue of high-temperature engine components,motion assembly friction and wear,structural dynamic load control,rapid detection of repair and maintenance,health monitoring,fault diagnosis secondary or multi-start,and wide-range thrust modulation should be researched emphatically.
