Abstract

Hypergolic thrusters have been extensively researched and applied to spacecraft propulsion based on their simplicity and high reliability of ignition. Research on the impingement characteristics of $N_2O_4$/amine has been profoundly carried out since the 1960s in advanced countries, especially the United States. Recently, enhancements to advanced hypergolic thrusters using MON/MMH have been planned by NASA to improve compactness and high performance. In this work, technical studies were investigated on the mixing of hypergolic propellant and its combustion instabilities such as reactive separation flow and popping.

접촉 점화 추진제 특성을 활용한 추력기는 간단한 시스템 구조와 높은 점화 신뢰성을 기반으로 고고도, 우주 환경에서 적용되어 왔다. 미국을 위시한 선진국의 경우 사산화질소/아민 계열의 추진제의 충돌 혼합 특성에 대하여 1960년대 이후로 심도 깊은 연구를 진행하고 있으며, 최근 차세대 접촉 점화 추력기 역시 고성능화, 경량화 측면에서 활발한 연구 개발을 수행하고 있다. 본 논문에서는 접촉 점화성 추진제의 충돌형 혼합 특성과 반응성 유동 분리(Reactive Separation Flow), 간헐적 폭발(Popping)의 충돌 혼합 시 발생할 수 있는 연소 불안정성에 대한 연구 사례를 조사하고 요약하였다.
