초록

한국형발사체 3단에 사용하기 위한 7톤급 엔진의 개발 시험 결과를 제시하였다. 2기의 engineering model 엔진을 가지고 수행된 연소시험은 시험조건에 따라 지상 시험과 고공 시험으로 구분된다. 엔진의 작동성 검증을 위해 수행된 short duration과 long duration 시험은 성공적으로 완료되었다. 내구성 검증을 위해 수행된 full duration 시험에서는 일부 개선 사항들이 발견되었다. 종합적으로, 엔진 개발에 힘을 더할 수 있는 고무적인 데이터들이 7톤급 엔진 시험으로부터 획득되었다. 이 결과를 바탕으로 새 엔진들이 제작되고, 제작된 엔진은 연소시험을 통해 지속적으로 검증될 예정이다.

The test results of a 7-tonf-class engine for the third-stage engine of KSLV-II are presented. Hot-firing tests performed with two engineering model engines are classified into ground tests and high-altitude tests according to the test conditions. The operability verification of the engines were carried out through short and long duration tests. The full duration test performed for the durability verification of the engines revealed a few of items to be improved. Synthetically, encouraging data of adding power to engine development were obtained from the test results. New engines based on these results will be manufactured and consistently verified through hot-firing tests.
