 Tank test for investigating into underwater fin effect for advanced sail-assisted ships(Gallery, Marine Dynamics Research Group) |
 |
Effect of position and area of fins upon hydrodynamic forces acting on a model of an advanced sail-assisted ship were investigated by towing tank test. Six kinds of fin arrangements were compared. |
  Fore center finA fin attached at bottom of bow along centerline of a model ship. |
 Parallel part finsTwo fins at bottom of both sides at parallel part. |
 Aft finA fin attached at bottom of stern along centerline of a model ship. |
 Measurement of hydrodynamic forcesHydrodynamic forces acting on a model ship with fins in oblique motion were measured. Effect of heel angle was also investigated. |
