We have developed the gas-generator to drive the turbo-pump for a LH2/LOX rocket engine of 7,000 kg-thrust level. The present gas-generator is the reverse-flow type which is composed of a spherical combustion chamber with a turbulence ring, uniform mixture ratio-coaxial injectors and a start valve. The performance characteristics and functions of the gas-generator have been verified through eight running tests of gas-generators themselves and ten running tests of the second gas-generator assembled to a turbine. Total burning duration is 204 seconds. Here are presented the design details of gas-generators developed at the Institute of Space and Aeronautical Science (ISAS), University of Tokyo, the test facilities and the test results obtained up to date.
