[0019] The following detailed description of the new concept of rolling and drag reduction ship of the present invention is given below in conjunction with the accompanying drawings:
[0020] The invention is a rolling and drag reduction device and a new concept ship equipped with the device. The main content is the improvement of the keel of traditional ships and the application of the hydrofoil device in ship drag reduction and roll reduction.
[0021] The purpose of the present invention is achieved as follows:
[0022] Rectangular hydrofoil devices are arranged in tandem on the bilge of the main structure of the ship. The hydrofoil spacing is generally smaller than the chord length of the hydrofoil, and the arrangement position is roughly equivalent to the bilge keel. The number and spacing of hydrofoils need to be adjusted according to the ship's own swaying motion characteristics. When the ship moves, the wings move together, and at the same time, the hydrofoil can rotate arou...
