Abstract

The development of an underwater rocket propulsion system was described in this paper. Throttle able liquid propellant and hybrid rocket propulsion systems were selected for underwater propulsion. A subscale liquid rocket combustion chamber and it's portable stand were developed and their applicability was examined. 1.5-ton.f and 1.8-ton.f hybrid rockets were developed for underwater applications. The test results indicated that the 18-ton.f hybrid rocket fully complies to the performance and underwater cruise stability requirements; thus, its development was concluded to be successfully complete.

수중운용 체계를 위한 로켓추진기관 개발에 대해 기술하였다. 추력조절이 가능한 LP(Liquid Propellant rocket)형 추진기관 및 HR(Hybrid Rocket)형 추진기관을 선정하여 시스템으로의 적용 가능성을 확인하였다. 축소형 액체로켓연소기 및 이동형 시험대를 개발하여 적용 가능성을 검토하였으며, 수상체계 적용을 위한 추력 1.5톤급 및 추력 1.8톤급 하이브리드 로켓 추진기관을 개발하였다. 시험결과 1.8-톤급 하이브리드 로켓이 수상운용을 위한 추진기관 요구 성능 및 수중 주행 안정성 목표를 성공적으로 달성하였다.
