Abstract

Since the late 1990s, the demand for developing green or reduced-toxic storable propellants has been rising to replace the existing toxic propellants. Most of the research activities are focusing on development of new hypergolic fuels and either white fuming nitric acid or hydrogen peroxide is utilized as an oxidizer. The newly-developed hypergolic fuels are classified as three types, catalytic fuel, reactive fuel, and ionic fuel. In the present study, recent R&D trend of ionic liquid propellants is described and the main results in the previous studies are analyzed.

1990년대부터 기존 맹독성 이원추진제를 대체하기 위해 수행되어 오던 친환경 혹은 저독성 이원추진제 조합에 관한 연구는 최근 우주 추진기술 개발과정에서 경제성, 안정성, 효율성 등이 강조되며 더욱 주목받고 있다. 연구활동은 주로 저독성 하이퍼골릭 연료를 개발하는 것에 집중되어 왔으며 백연질산 혹은 고농도 과산화수소 산화제로 사용하였다. 저독성 하이퍼골릭 연료의 종류는 촉매성 연료, 반응성 연료, 이온성 연료로 구분할 수 있다. 본 논문에서는 하이퍼골릭 이온성 연료의 연구개발 동향을 소개하고 선행연구에서 보고된 주요 결과들에 대해 분석하고자 한다.
