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 1):
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 at a bow part of the ship beginning from a waterline going to a bottom of the ship, and then 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 an air jet is directed backwards or backwards with a slight slope downward to push the ship forward and in a way to let the air to be evenly distributed over two sides of the ship; wherein the air injectors are installed as one row in a middle or as two rows separately for each side, the injectors are designed in a way to let the air rising upward could dissipate and cover an entire area of the sides submerged in the water and create an air layer between the ship and water to reduce the friction between the ship and water surface; wherein the bow part injectors are performed in a way to make it possible to direct the air to create an air space in front at the moment of ship upfloat to reduce a water resistance at the bow part of the ship.
