摘要： PURPOSE:To suppress motion of a hull by controlling feed air to an air cushion chamber. CONSTITUTION:In an air cushion chamber 7 in a ship bottom part of an air cushion ship, partition members 5, 6 dividing the air cushion chamber 7 into right and left section chambers and front and rear section chambers are arranged, while a duct, which is used for feeding air to each of the section chambers 7F1, 7F2, 7A1, 7A2 from a lift fan, and louvers 8F1, 8F2, 8A1, 8A2, which can be controlled so as to be opened/closed, in air supply ports to each section chamber in the duct are installed. In this way, if a hull is rolled, opening of each of the louvers is controlled for regulating air supply quantity, and consequently, motion of the hull can be suppressed.

摘要： PURPOSE:To control the angle of elevation of a hydrofoil to a proper value according to sailing conditions. CONSTITUTION:Since when a hydrofoil 5 is exposed to air owing to waves, the lift of the hydrofoil 5 is reduced to zero, this is detected and an angle of elevation is minimized and the hydrofoil 5 is controlled by a controller 25 so that after a lapse of a specified time, the angle of elevation is adjusted to a preset value. This constitution prevents the occurrence of an impact during re-rushing in water and prevents the occurrence of a stall and residence of air on the back of a wing for a long period, whereby sailing in waves without lowering performance of the hydrofoil 5 is facilitated.

摘要： PURPOSE:To prevent lowering of a pusher by a method wherein a ship bottom is divided into a front ship bottom positioned in a deep position and a rear ship bottom positioned in a shallow position by a difference in level, and protrusion parts on the gunwale side the inner surfaces of which are vertical are formed on the two gunwales of a ship bottom throughout a range extending from a position in front of the difference in level to the rear end of a ship hull. CONSTITUTION:A ship bottom is divided into two parts of the one being a front ship bottom 2 positioned in a deep position and the other being a rear ship bottom 3 positioned in a shallow position by a difference in level 4. Protrusion parts 8 on the gunwale side each starting from the intermediate of the front ship bottom 2 to the rearmost end of a ship hull 1 are formed in succession on both gunwales of the ship bottom. A sectional shape is an acute state, and protruded downward in a state to incline toward the inside so that an inner surface 8a is extended almost vertical. A ship bottom protrusion 9 is formed in a moderate V-shape in cross section and protruded in such a shape that the protrusion part starts from the intermediate part of the rear ship bottom 3 to the rear end part of the ship body 1, and depth and width are gradually increased toward the rear end of the ship hull 1 and at a last end, the protrusion occupies almost the whole width of the rear ship bottom 3 and a lower end is extended to a position deeper than the protrusion part 8 on the gunwale side.

摘要： PURPOSE:To improve steering function by providing necking at a connection part between a strut and a flap rudder to reduce a negative peak pressure when a flap angle is increased and retard the generation of cavitation and resultant ventilation. CONSTITUTION:In the horizontal cross-section forms of a strut 3 and a flap rudder 4 in which the flap rudder 4 is connected rotatably to the rear of the strap 3 suspended from a hull, necking 7 is formed at a connection part 6 of these two so that the direction of a tangential line at the rear end of the strut 3 always crosses the flap rudder 4, or an aerofoil section independent of the strut 3 and flap rudder 4 is formed so that the virtual rear edge 3a of the strut is located ahead of the rear edge 4a of the flap rudder 4.
