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 9):
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 the airway ducts and the flow control valves is connected to the receivers, the air separation duct is mechanically fixed in a bow part of the ship, beginning from a waterline and to a ship bottom, and then the air separation duct continues along the bottom of the ship to an aft, and the air injectors are fixed at the air separation duct at different distances from each other depending on a specific situation so that the air jet could be directed backwards or backwards with a slight slope downward to push the ship forward and in a way the air can be evenly distributed along two sides of the ship and the airway ducts are fixed on the sides of a watercraft to let the air along the airway ducts to pass backwards and upwards; wherein the airway duct is performed as a flat metal triangle or other shape and is mechanically fixed on the sides of the ship from an upper side or from the upper and a front sides, depending on the shape and location, sloped downwards for form the airway duct by a flattened metal and a hull side, and in a way to make a back side of the airway duct higher so the air would go up and back in the airway duct to push the ship forward, wherein the airway ducts are made in shape of a metal corner or as other shaped profile and are embedded in the sides of the ship from inside, and there is an opening of a rectangular or triangular shape cut in the hull side so the air rise from the bottom of the ship and enter a slot in the sides and along the airway ducts fixed to the sides on the inside could pass up and back, at that the airway ducts are narrowed beginning from a front lower part so the air passing backwards could gradually pass through sides of the airway duct to maintain an air layer between the ship and the water, wherein the airway ducts along a width and a length are different, an angle between a flat metal and the hull side, the slope of the airway ducts from a horizontal plane is different and shall be calculated individually for each ship; wherein in cases a surface mounted external airway ducts are used, they are installed in a way first ones cover next ones up to the aft part, resembling a semi-open and sloped down fish scales, wherein the airway ducts may be of a different profile, and on the sides of the ship are installed in horizontal rows, on a different distance between rows, wherein the air duct can also overlap each other.
