압력차를 이용한 선박 항해시스템 개발에 관한 연구 = A Study on Development of Ship Steering System with Aerated Liquids

다국어 초록 (Multilingual Abstract)

Generally a ship in a port or canal is guided by tugboat(s), while the ship engine(s) and steering mechanism are idle. The shortcomings of this method are insufficient course keeping ability, danger of collision with waterside structures, time-consuming preparation for tugging, as well as the need to maintain tugboats. A new technology for ship guiding, based on the physical principle of interaction of a solid body with aerated liquids has been developed [1]. Model tests were carried out for the verification of system at slow speed by engine operating conditions with an idle steering. The developed device has been proved to keep the ship on course safely.
