Abstract

After-burner test facility for gas generators of 75 tonf class liquid rocket engines was designed, which was verified by the facility certification test of the Combustion Chamber Test Facility(CCTF). The purpose of the certification test of the after-burner test facility is to verify the combustion stability of gas torches equipped in the gas generator and the after-burner test facility by using methane and oxygen gases. In the case of the autonomous test, the supply system provided steadily methane and oxygen gases to the after-burner system without pressure drop. The combustion pressure of the gas torch approached the design requirement. In the case of the coupled test, the gas generator ignition and the fuel-rich exhaust gas combustion were successfully carried out, leading to the verification of the test facility.

75톤급 액체로켓엔진용 가스발생기 후연소 시스템 설비를 제작하였으며, 연소기 연소시험설비 시험장에서의 설비인증 시험을 통해 그 성능을 확인하였다. 후연소 설비인증 시험은 메탄과 산소의 공급성능, 가스발생기와 후연소 설비에 설치된 가스토치의 안정적인 연소 능력을 검증하는데 있다. 단독성능 시험에서 공급시스템은 감압 없이 일정한 압력으로 메탄과 산소를 공급했으며, 가스 토치 압력은 설계조건을 만족하였다. 가스발생기 점화용 가스토치와의 연계시험에서 가스발생기 점화 성능과 연료과농 배기가스의 후연소 성능에 관한 인증 시험을 성공적으로 수행하였다.
