Abstract

In this study, we selected CFRP to construct a canoe hull. A ship design was made using a commercial ship design program, SOLIDWORKS, and a flow analysis of the canoe on a free surface was calculated using STAR-CCM+. A flow field and waveform were obtained in this way. These results were used to check the resistant performance of the canoe. Results showed that if the draft is 0.09 m, it is safe to run at less than 4 m/s, and if draft is 0.24 m, it is safe to run at less than 2 m/s. Moreover, it was confirmed that those speeds can be made by two adults. The developed canoe, which is 20 % lighter in comparison with conventional FRP models, was briefly introduced in this paper.

본 연구에서는 카누 선체 재료를 탄소섬유복합재료로 선정하였으며, 선형설계는 선박 설계 상용프로그램인 SOLIDWORKS를 이용하여 수행하였다. 카누의 유동해석은 상용프로그램인 STAR-CCM+를 이용하여 자유수면의 파형을 살펴보고 수치해석 결과를 통하여 저항성능을 확인하였다. 그 결과, 흘수가 0.09 m일 경우에 4 m/s 미만의 선속으로, 흘수가 0.24 m인 경우에는 2 m/s 미만으로 운항하면 안전하다고 판단되며, 두 명의 성인이 속도를 내는 데에도 무리가 없음을 확인하였다. 또한, 해석결과를 적용하고 CFRP를 이용하여, 기존의 재료보다 20 % 가볍게 제작된 카누에 대해서도 간략히 소개하였다.
