Abstract

A research area on liquid rocket engine has been suggested. Downsizing through combustion pressure rise and low price are major issues to gas generator cycle engines. A very high pressure turbopump and material against oxidizer rich environment may be necessary technologies for staged combustion cycle engines. Integrated analysis saving computing time is the trend of rocket engine systems analysis area. Other important research topics are the methane engine for reusable booster to reduce the cost, 3D printing and materials for high temperature or oxidizer rich environment.

액체로켓엔진의 향후 연구 분야를 제안하였다. 가스발생기 사이클 엔진은 고압화를 통한 다운사이징, 가격경쟁력 확보가 중요 이슈가 될 것이다. 다단연소 사이클 엔진 분야에서는 초고압 터보펌프 개발과 내산화성 소재 개발이 필요할 것으로 기대된다. 로켓엔진 시스템 해석기술 분야에서는 해석 시간절감을 위한 통합화 경향이 예상된다. 이외에도 비용절감을 위한 재사용이 가능한 부스터급 메탄엔진, 3D 프린터를 활용한 제작, 내열/내산화성 소재 개발 등이 주요 연구 주제가 될 것으로 판단된다.
