Title:
水中翼付き船
Document Type and Number:
Japanese Patent JP4051165
Kind Code:
B2
Abstract:
A hydrofoil (1) comprises a bottom (23) formed with two front and rear steps (3 and 4), and a strut (31) supporting a submerged hydrofoil (21) arranged between the two steps (3 and 4). The strut (31) can be switched between a storage state and a navigation state by its forward-and-backward rotation. A threshold value of dynamic lift (F) obtained by the hydrofoil (21) can be established arbitrarily, and the dynamic lift can be held to the set value by keeping the strut (31) in the navigation state correspondingly to the established threshold value of hydrofoil-dynamic-lift, thereby enabling the dynamic lift to be held at the established value during navigation. Moreover, based on draft (WL) or trim angle (TR) during the boat-berthing, a set value of hydrofoil-dynamic-lift and a set value of tilt angle of a propulsor (22) or a flap (22a) attached to the rear of hull can be accommodated.
