5 N 급 ADN 기반 단일추진제 추력기 예비 연소 시험 = 5 N Scale Preliminary Thruster Test with an ADN-based Monopropellant

다국어 초록 (Multilingual Abstract)

This paper reports the preliminary firing test performed with an ADN-based monopropellant using a 5 N scale thruster. ADN-based propellant and catalyst was fabricated and catalytic combustion of propellant was characterized by DSC-TG analysis. Although an explosion in the catalyst bed was occurred, high temperature in the catalyst bed obtained and demonstrated catalytic combustion of the propellant. Preliminary test results motivates the research for catalysts with better thermal stability.

5 N 급 단일추진제 추력기를 이용하여 ADN 기반 고성능 친환경 단일추진제의 연소 시험을 수행했다. ADN 기반 추진제 및 촉매의 제작을 진행했으며, DSC-TG 분석을 통한 검증을 진행했다. 연소 시험 시 촉매 반응기 내에서 작은 규모의 연소 불안정 현상이 발생했지만, 촉매 반응기 전단에서의 높은 온도를 관찰하여 제작된 추진제의 촉매 연소가 발생했음을 파악했다. 향후 보다 높은 열적 안정성을 확보하기 위해 추진제의 높은 단열 분해 온도를 견딜 수 있는 촉매의 개발을 수행하고 이를 적용할 예정이다.
