PROGRESS IN STUDIES ON TEST FACILITY AND EXPERIMENTAL TECHNIQUE FOR MODEL SCRAMJET

Scramjet is an advanced propulsion system for hypersonic vehicles and plays very important roles in both fundamental researches and engineering applications. The construction of the test facilities and the development of the experimental techniques for scramjet investigation signify a national potential in aerospace field. The present paper summarized the development of scramjets and its ground test facilities in the world. It also introduced the first model scramjet test facility in China, called HPTF (Hypersonic Propulsion Test Facility), with the basic considerations and studies in the design and construction of its key elements. The preliminary calibration and testing results were also discussed. This facility provides a basic experiment conditions for model scramjet tests with the operational parameters of Mach number of 5.8, total pressure of 5MPa, total temperature of 2 000 K and total mass flow rate of 4.5 kg/s.
