초록

한국항공우주연구원의 자유제트형 지상추진시험설비인 스크램제트 엔진 시험설비의 마하 5 조건에서 스크램제트 엔진 흡입구의 성능분석 시험을 진행하였다. 스크램제트 엔진 흡입구의 대표적인 성능 인자인 전압력 회복률, 공기 포획율 측정을 위하여 격리부 후방에 설치되는 피토/정압 레이크가 설계 제작되었다. 격리부 후방에 장착된 레이크가 전방의 흡입구 램프와 격리부에 미치는 영향과 레이크로 측정된 흡입구의 성능 인자 분석 그리고 흡입구의 받음각 변화에 따른 벽면 정압력 분포 변화에 대한 분석이 수행되었다. 끝으로 연소기에서의 압력 상승을 모사하는 장치인 흡입구 후방 배압 조정 장치를 이용하여 흡입구 불시동이 발생하는 시점을 확인하였으며, 본 논문에는 그 결과를 정리하였다.

The performance analysis test of the scramjet engine intake was conducted under the Mach 5 condition of the scramjet engine test facility, a free-jet ground test facility of the Korea Aerospace Research Institute. A pitot/static pressure rake installed at the rear of the isolator was designed and manufactured to measure the total pressure recovery rate and mass capture ratio, which are typical performance factors of the scramjet engine intake. The effect of the rake mounted at the rear of the isolator on the intake, the performance analysis measured by the rake, and the change in wall static pressure distribution according to the angle of attack were performed. Finally, the point at which the intake unstart occurred was confirmed by using the rear back pressure adjusting device, which simulates pressure rise in the combustor, and the results are summarized in this paper.
