HIGH SPEED SHIP

摘要

The invention relates to shipbuilding and to the construction design of speed ships moving in a transition regime at a most optimum speed (Froud number with respect to displacement ranges from 1.0 to 3). The inventive speed ship comprises a hull with a keelbuilt bottom and active pullout elements controlling lifting force. In the aft part, the ship is fitted with projecting bearing parts having a blunt rear edge. The lower surface of each projecting bearing part is arranged on both sides of a keel and on a plane with the adjacent bottom surface forming at the deadrise angle therewith of up to 15 DEG . The length of the projecting bearing parts ranges from 0.1 to 0.5 of the ship hull length and the thickness thereof decreases away from the stern to the rostrum. The ratio of the ship's beam fitted with the projecting bearing parts to the beam of the hull ranges from 1.2 to 2.5. The active elements controlling lifting force are arranged directly behind the blunt rear edge of the projecting bearing parts. Submerged wings with a surface ranging from 3 to 20 % of a waterline area can be arranged in the forebody, in the middle and in the aft end of the ship. Said wings can be fixed directly to the ship's hull or by means of a central pillar (T-wing).
