Combustion Characteristics of Technology Demonstration Model for Staged Combustion Cycle Engine
다단연소사이클 엔진 시스템 기술검증시제 연소성능 평가
Abstract
High performance upper stage engine is necessary for space launch vehicles of geostationary orbit, and staged combustion cycle engine is suitable due to high specific impulse. Technology demonstration model for 9 tonf class staged combustion cycle engine, which is consisted of turbopump, preburner, combustion chamber and supply system, was assembled, and hot-firing test was conducted for three seconds in Upper-stage Engine Test Facility of Naro Space Center. Ignition, combustion and shut down of engine system was performed normally, and its performance parameters were evaluated.
정지궤도용 우주발사체에는 고성능 상단엔진이 필수적이며 높은 비추력을 가지는 다단연소사이클 엔진이 적합하다. 터보펌프, 예연소기, 연소기, 공급계 시스템으로 구성된 9톤급 다단연소사이클 엔진 시스템의 기술검증시제를 제작하여 나로우주센터 3단 엔진 연소시험설비에서 3초 지상연소시험을 수행하였다. 엔진 시스템의 시동, 점화, 연소 및 종료가 정상적으로 수행되었으며 주요 성능 변수를 평가하였다.
