Abstract

A development of monopropellant thruster for microsatellite that uses concentrated hydrogen peroxide is described. Catalyst, the most important component in the thruster, was prepared and coated on a monolith honeycomb. Performance evaluation of thruster was peformed by considering the efficiency of characteristic velocity and ignition delay. As a result, 96.0% of $C^*$ efficiency was obtained at designed propellant flowrate and steady state operating condition.

마이크로위성의 임무능력 향상을 위한 과산화수소 단일추진제 마이크로 추력기를 개발하였다. 단일 추진제 추력기의 핵심 요소인 촉매를 모노리스 지지체에 담지/제작하였으며 특성속도 효율, 반응지연 시간 측정을 통해 추력기 성능평가를 수행하였다. 실험결과 정상상태 설계 유량에서 96.0%의 높은 특성속도 효율을 확인하였다.
