  • In order to know the characteristics of the hypersonic air-breahting engine, high altitude and Mach number ground test is necessary. Therefore, high pressure and high temperature condition should be simulated to do ground test of the hypersonic air-breathing engine. In this paper, the hypersonic air-breathing engine ground test facility of the Korea Aerospace Research Institute was introduced and the composition and characteristics were described.

  • Advanced countries in aerospace have been struggle to realize the hypersonic air-breathing system since originating the concept of the hypersonic air-breathing propulsion system during the first half of the twentieth century. At last, NASA's X-43A Hyper-X did successful Mach 10 flight in November 2004. Each countries are running the program to applicate this hypersonic air-breathing propulsion system to SSTO(Single Stage to Orbit) or TSTO(Two Stage to Orbit) vehicle or hypersonic missile system at present. In this paper, we wrote the history and current issues of the hypersonic air-breathing propulsion system and hypersonic flight with the hypersonic air-breathing propulsion system.

  • 이 글에서는 극초음속 항공우주 비행기의 개요 및 개발배경, 구조기능 및 추진체계, 그리고 개발 및 설계의 제반고려사항 등에 관하여 알아보았다. 단단계형 공기흡입식 추진체계라는 새로운 개념의 도입은 미래 극초음속 비행체의 재활전용성과 항공 및 우주의 운항 용이성이라는 두 가 지의 가능성을 제시한다는 점에서 큰 의미를 갖고 있다. 극초음속 항공우주비행기의 실현가능 성은 공기흡입식 추진체계의 핵심부분인 스크램제트엔진 개발의 성공여부에 달려 있다고 하겠다. 이러한 스크램제트엔진에 관한 연구 및 개발은 현재 진행중이며, 오늘날 첨단 추진체 연구분야 중의 하나로 여겨지고 있다.

  • The Air-breathing engine like Sea-Star I is a second propulsive force generator to fly to the target after the booster generating initial propulsive force is separated. The performance of Sea-Star I engine should be verified because the cruise missile controls direction and altitude during flight, so ground engine test is executed before flight test. This these presents evaluation method of ground engine test to verify performance of Sea-Star I's engine.

  • The component based propulsion modeling and simulation of an air-breathing engine such as ramjet and scramjet is studied. The simulation model has been realized considering the characteristics of the air-breathing engine which is composed of air intake, combustor and nozzle including engine controller and fuel supply system. To estimate the engine performance and to verify the engine controller, real time based Hardware in the Loop System simulating actual environment is constructed.
