초록

초공동현상을 이용한 고속 수중 운동체와 함께 이를 가능하게 하는 기술로써 해수흡입 램젯 추진에 대한 연구가 여러 나라에서 진행되고 있다. 본 연구에서는 해수 흡입 램젯 엔진을 추진기관으로 하는 수중 운동체의 개념 설계를 진행하였다. 가동 환경을 확인하여 임무 작동 조건을 설정하였으며, 해당 조건 내에서 초공동현상 이론과 유체역학적 지식을 통해 운동체에 작용하는 항력을 예측하였다. 이로부터 필요 추력을 산출하여 추진기관의 대략적인 사이징과 부분별 성능해석을 수행하였으며, 설계한 추진기관의 추력 및 비추력 성능을 확인하였다.

Many countries are paying efforts to the research and development of water-breathing ramjet propulsion for submersible vehicle with the super-cavitation which makes traveling at high speed in underwater possible. In this study, a conceptual design of an underwater vehicle with water-breathing ramjet was carried out. Mission profiles and operating conditions are determined by examining the operation environment. Drag is estimated based on the theories of super-cavitation and fluid mechanics. The sizing and performance analysis of the components were performed using thrust required, thrust and specific impulse of designed engine were verified.
