Abstract

Recently, a vessel's maneuvering performance is considered to be an important subject to secure safety at short sea shipping. Especially the high turning performance, which is required to avoid the marine pollution by the ships that was grounded, becomes more severe. In this paper, we discuss the effect of increasing rudder force on turning performance of short sea shipping ship by free running test in towing tank. First of all, we make the 47K PC model ship and high-lift rudder using Coanda effect. And we make the free running test system for the turning test in towing tank. And also we perform the turing test of 47K PC model in several changes of Coanda jet momentum and evaluate the turing performance such as advance and tactical diameter. Finally, we confirm that the increasing of rudder force is very effective to improvement of turning performance of short sea shipping ship.

안전하며 친환경적인 근해운송시스템을 확보하기 위해서는 운송 수단인 선박의 안전한 운항 확보가 필수적이다. 특히 좌초, 충돌 등의 해난사고를 방지하기 위해서는 선박이 우수한 조종성능을 갖는 것이 요구되며 특히 조종성능 중에서 선회성능은 충돌 회피 등에 필수적인 성능이다. 본 연구에서는 선박에 부착된 조타기의 타력 증가가 선박의 선회성능에 미치는 영향을 모형선 실험을 통하여 고찰하였다. 먼저 Coanda 효과를 이용한 고 양력 타 장치 모형과 47 K PC의 모형선을 제작하였다. 또한 모형선의 선회 성능 실험을 위한 자유항주시스템을 구축하고 사각 수조에서의 타력 증가 값을 변화시켜가면서 모형선의 선회 성능을 계측하여 타력 증가에 따른 선회 성능의 변화를 평가하였다. 모형선의 선회성능 실험결과를 통해 타력 증가가 근해운송 선박의 선회 성능 향상에 효과적인 것을 확인하였다.
