A Study on Design Constraints of a Supercavitating Underwater Vehicle
Journal of the Society of Naval Architects of Korea, 2016 기존의 수중운동체는 물과 완전히 접촉한 상태로 운동하며 이 때 물에 의한 마찰저항으로 인하여 운동의 속력 한계가 존재한 다. 초공동 기술은 수중운동체를 공동(cavitation)으로 감싸 물과 의 접촉면을 줄여 마찰저항을 감소시킴으로써 수중운동체 주행 속도를 크게 증가시킬 수 있는 기술이다. 초공동 기술은 군사선 진국을 필두로 1970년대부터 꾸준히 연구되고 있는 분야이다. 최근 국내에서도 초공동 관련 기초연구가 국방과학연구소 주관 으로 꾸준히 수행되고 있고 관련 논문도 다수 발표된 바 있다 (Ahn, et al., 2012; Kim & Lee, 2014; Kim, et al., 2013; Kim & Kim, 2014 ...

Trajectory Optimization Strategies for Supercavitating Underwater Vehicles
, 2004 Supercavitating vehicles are characterized by substantially reduced hydrodynamic drag with respect to fully wetted underwater vehicles. Drag is localized at the nose of the vehicle, where a cavitator generates a cavity that completely envelops the body ...
