Abstract:
The invention relates to shipbuilding and can be used in reconditioning in order to economize fuel and to increase speed. The technical problem is solved by the shipboard installation of air compressors, air receiver tanks, pass valves, air conduits, air separating conduits, air intakes and air injectors, which are interconnected by air ducts. An air separating conduit is mechanically secured in the bow of the ship and has air injectors secured along the centre thereof up to the stern. The injectors direct a jet of air backwards so that the jet of air thrusts the ship forwards, then the air rises along the sides of the ship, maintaining a layer of air between the ship and the water, thus reducing water resistance. The injectors in the bow direct a jet of air such that the ship is constantly sailing into an air space.

Claim (Index 7):
A ship including air compressors, flow control valves, air intakes, receivers, airway ducts, air separation ducts and air injectors, wherein the air separation duct through airway ducts and flow control valves is connected to the receivers, the air separation duct is mechanically fixed on sides of the ship, on a bow part of the ship and at a ship bottom transversally to a length of the ship and in horizontal plane, several rows at different heights of the submerged part of the ship hull, several air injectors are mechanically fastened on the air-separation duct depending on the breadth of the ship, several air injectors are directed parallel to a downward slope of the bow part of the ship and backward in different order and direction depending on a specific site of their installation, the injectors are self-adjustable and are installed on the air separation duct in a way to let the air to be supplied in front of the ship and under the ship along a whole width at once, and in any case are directed backwards or with a slight slope in different directions, in a way to let the air jet to push the ship forward or forward and upward, the bow part and the oval bottom of the ship are wide and flattened, the bow part of the ship is sloped backward beginning from a waterline at different angles and the bottom is sloped upward at different angles starting from the front at different points along the length of the ship in a way to let the air along the bottom retreat and push the ship forward; the ship bottom can also be sloped downwards starting from the bow part at different angles so that at a speed the ship could travel supported by an air cushion upward and forward, in this case a rear side is extended from the bottom to the side and forward in a way to let the air up along the rear side to pressed the rear side and push the ship forward and upward.
