The feasibility of GG cycle reusable rocket engine is examined in this study based on the requirements of JAXA reference mission. Bioethanol is used as fuel and LOX is used as oxidizer. The combustion chamber pressure, the expansion ratio and the fuel injection temperature are set to 7 MPaA, 25 and 390 K. As a result, 0.6 in its turbine/pomp efficiency and 0.954 in its Isp efficiency are needed to satisfy the mission requirements. Besides, the experimental study was conducted to confirm the validity of anticorrosion coating on A6061 alloy in high-pressure and high-temperature ethanol.
