초록

47.7m급 쌍동선의 1/21.5 축척 모형선으로 예인수조에서 저항 및 내항성능 시험을 수행하였다. 저항 시험은 선미트림탭을 부착하여 트림탭각의 변화에 따른 트림 및 저항변화를 조사하여 트림 탭이 없는 경우와 비교하고 그 영향을 조사하였다. 해상상태 3,4 및 5에서 3가지 실선속력에 대해서 상하 및 종운동을 계측하였으며 갑판위 5점에서 수직가속도도 계측하였다. 측정한 가속도 값은 ISO 2631/3의 규정과 비교하여 설계선형의 우수함을 보였다.

The seakeeping and resistance tests of a 47.7m class catamaran are conducted in a towing tank with the 1/21.5 scale model. The effect of the trim tab on the resistance is investigated with the trim tab angle variations and the resistance and trim angle of the catamaran with the trim tab are compared with those without the trim tab. The heave and pitch motions are measured at the three full scale speeds in sea state of 3.4 and 5 and the vertical accelerations at five points on the deck are also measured. The measured accelerations are compared with the criteria of ISO 2631/3 and it is shown that the seakeeping performance of the catamaran is good.
