Abstract

Present paper introduces the recent advances in space launch vehicle technologies. A brief survey is given for the space development programs in civil sector with their business model and key technologies. Advances in key technologies were reviewed in detail with more emphasis on the electric pump cycle engine for low cost high performance small launch vehicle, Electron, under development by Rocketlab Ltd., since their contributions would give good lessons for rocket scientists.

본 논문에서는 최근의 우주발사체 기술 발전에 대한 소개가 이루질 것이다. 민간 분야에서의 우주개발 사업들의 사업 모델 및 핵심 기술에 대하여 간단한 정리하고, 핵심 기술의 발전 사항들에 대하여 좀 더 구체적으로 살펴볼 것이다. 특히 Rocketlab 사가 개발 중인 저가 고성능 경량 우주발사체 Electron 에 사용될 예정인 전기펌프 사이클 엔진에 대하여 좀 더 구체적으로 살펴보고, 이들이 로켓 과학자들에게 주는 시사점에 대하여 살펴볼 것이다.
