The rocket-ramjet combined-cycle engine is studied for the next space transportation in JAXA. The engine realizes a higher effective specific impulse than that of the conventional rocket engines. Engine model combustion tests were conducted at in the ejector-jet mode at a sea-level static-air condition and in the ramjet mode at a Mach 4 flight condition, and are planed in the scramjet mode at Mach 6. Flight tests with the CAMUI rocket are planed for the ejector-jet system design technology. Aerodynamic tests and combustor tests are conducted to modify the engine design technologies. Studies on the high enthalpy flow and light weight material are also conducted.
