풍력 레저선박의 돛 받음각과 횡력에 대한 복원력 특성

다국어 초록 (Multilingual Abstract)

Characteristics of restoring force for the wind-powered leisure boat was investigated using mathematical formulation and commercial computational method such as the ANSYS Workbench CFX-Mesh. The objective is to find the restoring moment and heel moment while boat is sailing in windy power. Conditions for angle of attack were given from 5° to 90°. It is known that side force is larger in terms of angle of attack is higher, however critical angle is suggested to limit before over of 60° for safe navigation for boat in wind. Natural results are found that stronger heel moment is observed when sail is used than no sail, and higher angle of attack is induced stronger heel moment.
