Research Abstract

We developed a dynamic simulator for the hypersonic precooled turbojet including the unsteady models of the inlet unstart phenomenon and flow properties of two-phase hydrogen flow. Wind tunnel tests and numerical simulation clarify that the amplitude and frequency of the inlet buzz are determined by the inflow and outflow balance of the inlet and the duct volume located after the inlet. A capacitance-type void fraction meter was newly developed and relationship between the quality and heat transfer rate of the nitrogen was researched. The dynamic simulation agrees with the engine firing test.
