ABSTRACT	In the research and development of scramjet engines,flight tests are as important as ground tests and computer simulations.Extremely high stagnation temperature and pressure of the incoming air flow,which cannot be produced by ground test facilities,can be achieved in flight test.Thus,flight tests can be used to validate computer simulation codes.To achieve various technical breakthroughs,we propose three series of flight tests.Phase 0 is to establish a flight test system using a single sub-scale engine module attached on the top of a rocket booster and to compare the result with that of ground tests.In Phase I,effects of engine-airframe integration is tested at Mach 10.Larger engine modules are tested to investigate scale effects at Mach 16 in Phase II.Conceptual studies on the test vehicles and the engines for the three phases are conducted.
