Abstract

FIELD: water transport; designing high- speed passenger ships. SUBSTANCE: air under pressure is fed under bottom after fore planing step, ship has hull with closed space under her bottom for compressed air bounded with side skegs, power plant and steering gear. Above-mentioned space is bounded by rotated cylindrical wheels and pendulum-bucket propellers at the front and at the rear and by jets thrown by propeller from below. Besides that, sides of such ship may be made in form of aerodynamic profile and rudders may be fitted at ends of this profile. EFFECT: enhanced reliability. 2 cl, 2 dwg

Description

 The invention relates to water transport and for the construction of high-speed passenger ships.

 A high-speed vessel with air supply under pressure under the bottom of the vessel behind the bow redan is known, comprising a hull with the formation under its bottom of a closed space of compressed air limited on both sides by side skegs, a power plant and steering.

 However, such a vessel is characterized by high energy costs and slow.

 The technical result from the implementation of the invention is to reduce the energy costs of the vessel and to increase its speed.

 This technical result is achieved by the fact that in a high-speed vessel with air supply under pressure under the bottom for the nose redan containing the hull with the formation under its bottom of a closed space of compressed air limited on both sides by side skegs, the power plant and steering, the mentioned space in front and the rear is limited by rotary cylindrical wheels and pendulum-bucket propellers, and below - by water jets discarded by the propulsors.

 In addition, at such a vessel its sides can be made in the form of an aerodynamic profile, at the ends of which rudders can be placed.

 In FIG. 1 shows a high-speed vessel, side view; in FIG. 2 - the same, top view.

 The cylindrical wheels 1 of the high-speed vessel are located next to the pendulum-bucket propulsors 2 in the front and rear parts of the hull 3 of the described vessel. The vessel has a power plant and an installation for supplying air under the bottom (not shown). Cylindrical wheels 1, propulsors 2, side skegs 4 and jets of water discharged by propulsors 2, under the bottom of the hull of the vessel there is limited space of compressed air with excess pressure equal to 5 - 10 kPa (0.05 - 0.1 atm). The sides of the vessel have an aerodynamic profile with water and air rudders 5 at the ends.

 The described vessel is operated as follows.

 When the propulsion system rotates the propulsors 2 and the wheels 1, the lifting and pushing forces of the vessel arise, which determine its motion at a speed U. The water jets thrown by the propulsion device at a speed V back and down do not touch the bottom of the hull 3 of the vessel. In the water layers are only the lower sections of the skegs 4, which provide little resistance to movement. With insignificant resistance, the ship can develop speeds of the order of about aviation.

Claims (2)
