스크램제트 엔진 성능시험 설비를 위한 초음속 노즐 수치해석 및 성능시험

Korea Aerospace Research Institute has started the research and design of a scramjet engine and its test facility from 2000, and completed the development of the facility in July 2009. SETF(Scramjet Engine Test Facility), is a blow-down type wind tunnel equipped with a supersonic nozzle, storage air heater and air ejector. A supersonic nozzle and a storage air heater are used to simulate a flight Mach number condition. In this paper, numerical analysis and performance test for a brand-new supersonic nozzle of SETF is described. The nozzle is designed for Mach 6.0 flight condition.
