Description

This invention relates to shipbuilding, in particular to the construction of ship hulls.

The purpose of the invention is to increase efficiency by using wave energy.

FIG. 1 shows the hull of the vessel, side view; 2 is a section A-A in FIG. one; on fig.Z - section bb in figure 1; figure 4 - section bb In fig.Z.

The hull of the vessel 1 is made with side channels 2 in the plane of the waterline. On the vertical walls of the side channels 2, grilles 3 and air ducts 4 are installed. At the turn of the air duct 4, a receiver 5 is mounted. Air ducts 4 have a monotonously narrowing section and communicate with devices 6 in the underwater part of the water-air mixture release vessel. The vessel may have a second hull 7. The side canal 4 of the vessel may be provided with an additional grill 8, which functions as a barrier network. The dimensions of the grids 3 and 8 are made smaller than the sizes of the outlet openings on the sides, which is associated with the possible blocking of foreign outlets by the extrusions.

The wave, concentrating its energy in the side channels 2, penetrates through the grate 3 into the duct 4. Moving along the gradually narrowing section of the duct 4, water compresses the air that was previously in duct 4 and pumps it partially into the receiver 5, and the main part into the space between underwater part of the ship’s hull and the second hull or into specially built air ducts. Further, the air through the special dispensing devices 6 is discharged together with water from the outside of the underwater part of the hull and creates air lubrication. The number and location of the dispensing devices 6 is chosen so that the entire underwater part of the vessel is covered by them. The air ducts 4, located onboard, are interconnected so that the wave, striking it from any side, provides air lubrication of the entire underwater part of the vessel. Thus, the higher the sea level, the better conditions are created for hydrodynamic lubrication. Along the way for (

ABOUT

Water-filled air ducts 4 at the time of the impact of the waves create a recovery moment roll and help reduce the roll, i.e. work as passive tanks. In order to reduce the cubic capacity of the vessel, it is advisable to structurally combine the air ducts with the inner deck.

The receiver softens the effect of waves on the vessel, creates an air lubricant when the water turns, and contributes to a more rapid displacement of water from the horizontal duct after the wave stops, it increases the air supply time to the lubricant in the interval between the effects of alternating waves.

Claims (3)

Claim 1. The hull of the vessel, made with side channels in the plane of the waterline, is so that, in order to increase efficiency by using wave energy, in the vertical walls of the side channels are installed air ducts that are monotonically narrowing cross-section and communicated at the outlet with perforated devices for the release of air-air mixture, which is provided with the hull of the vessel in its underwater part, and turn - with a receiver, which is provided with the hull of the vessel. 2. A housing according to claim 1, characterized in that the air ducts communicate with each other. 3. Corps 1 and 2, characterized in that, at the entrance to the ducts, grilles are installed whose cell size is smaller than the openings of the devices for releasing the water-air mixture. mrauuuuA dlpp Thebes. g Phys. 1 Aa AT 6  m h 3 8-8 Fi & 4
