Abstract

This paper describes the results of standard motor tests by propellant formulation conducted for the development of long-duration DACS (Divert and Attitude Control System) and the system sizing derived from these results. Standard motor testing confirmed that stable combustion without the use of metallic stabilizers, and a burn rate correction factor was derived and applied to system sizing. The system sizing analysis indicates that propellant E is suitable for DCS (Divert Control System) and propellant A for ACS (Attitude Control System); the final selection, however, will be confirmed after additional evaluation of material compatibility.

본 논문에서는 장시간 위치자세제어장치(DACS) 개발을 위하여 수행한 추진제 조성별 표준모터 시험 결과와 이를 바탕으로 도출한 시스템 사이징 결과를 기술하였다. 표준모터 시험을 통해 금속 연소안정제 없이도 안정적인 연소가 가능함을 확인하였으며, 연소속도 보정계수를 도출하여 시스템 사이징에 활용하였다. 시스템 사이징 결과, 적합한 추진제는 위치제어장치(DCS)의 경우 propellant E, 자세제어장치(ACS)의 경우 propellant A로 판단되나, 추후 추진제와 DACS 추력기 소재의 적합성을 평가한 후 최종적으로 적합한 추진제를 선정할 계획이다.
