Abstract

In this paper, development and acceptance test results of 75-tonf class liquid rocket engine gas generators are described. Up to now, more than 330 times and cumulative time of 7,000 seconds gas generator autonomous tests have been carried out with 44 gas generator models. Through the tests it was verified that 75 tonf gas generator shows very reliable and reproducible characteristics in terms of chamber pressure, combustion efficiency, pressure loss, combustion stability, burnt gas temperature, and etc. 5 gas generators which are the last series of 75 tonf gas generator for the Korea Space Launch Vehicle II, will be manufactured until end of 2019 and their acceptance tests will be executed at the first half of 2020.

본 논문에는 75톤급 액체로켓엔진 가스발생기의 개발시험과 수락시험 결과가 기술되어 있다. 현재까지 44기의 가스발생기 모델을 이용하여 330회 이상, 누적 연소시간 7,000 초 이상의 가스발생기 단독 시험이 수행되었다. 시험을 통해 75톤급 가스발생기가 연소압력, 연소효율, 압력손실, 연소안정성, 연소가스 온도 등에서 신뢰성과 재현성이 높은 특성을 보여준다는 것이 확인되었다. 한국형발사체용 75톤급 가스발생기의 마지막 시리즈에 해당하는 5기는 2019년 말까지 제작 완료되어 2020년 상반기에 수락시험이 수행될 계획이다.
