Definitions
- the invention relates to the field of shipbuilding and can be used in modernization to save fuel and increase speed.
- marine vessels have been building different types according to one principle: an elongated hull with a sharp bow, to obtain the least resistance when moving on water.
- the prior art vessel (US 7997221 B2, 08/16/2011), which allows to reduce the resistance of water by placing air bubbles between the hull and the flow of water during its movement.
- the vessel contains an air compressor, a check valve, an air intake, an air duct.
- the vessel contains an air compressor, valves, an air intake, an air duct and an air separation duct.
- the specified source of information is selected as a prototype.
- the technical problem is solved by installing air compressors, receivers, check valves, air channels, air separation channels, air intakes and air injectors on the ship.
- Internal air channels are designed to connect the compressor to the air separation channel and air intakes.
- the air separation channel is mechanically fixed in the part of the vessel that is below the waterline, starting from the bow and continuing to the bottom of the vessel, and then along the bottom of the vessel to the stern.
- the air separation channel can consist of one whole or separate parts, and separately connected to the receivers, if necessary, they can be installed on other parts of the vessel, on the sides below the waterline.
- the air separation channel can be located outside the vessel, so and from the inside, and mechanically fixed on the bottom and on the bow, and can also be built-in.
- Air injectors are installed on the air separation channel, one row in the middle or two rows for each side separately. Injectors are different in size and can be self-regulating in any known way to change the direction of injection.
- the injectors direct the air stream back or back with a slight downward slope so that the air stream pushes the vessel forward, and then the air rises up along the sides of the vessel, creating an air gap between the vessel and the water, which significantly reduces the resistance of the water to the vessel.
- the injectors direct a stream of air straight down, or under a slight slope back, depending on the inclination of the bow of the ship so that an air space is formed in front of the ship, at the moment when the ship swims in with the bow, to remove water resistance from the front of the ship , and so that later the air rises along the sides of the vessel.
- the air separation channel with injectors can be installed in other places of the vessel, so that when leaving the air is directed back and down at an angle, and then rises up the sides of the vessel.
- Other air jet injectors are directed into the water under the ship or along the sides of the ship.
- the air mass that is thrown under the vessel tends to rise up under the pressure of the water and has potential energy that can be used as an auxiliary force when the vessel moves.
- air ducts are mechanically fixed along the sides of the vessel with an inclination upward from the rear side, so that the air goes up and back through the channels, the air ducts can also be cut into the ship's hull.
- the movement of air back and up the duct facilitates the movement of the vessel forward and is an air cushion for the vessel.
- the number of ducts and the slope of the ducts from horizontal is different and is calculated in each case separately to obtain maximum efficiency.
- Ducts begin to be installed from the bottom of the ship and to the waterline.
- External ducts are a flat or spherical profile, which is mechanically fixed to the sides of the vessel, with a downward slope, to obtain an air channel.
- Air ducts can be cut into the ship’s hull from the inside so that they look like a metal corner so that a channel is formed between the side and the upper side of the corner to allow air to pass through, and a corresponding opening is cut in the sides so that air rising along the sides of the vessel through the opening gets into the channel and it went up and back.
- External ducts can be long, from the bottom of the vessel to the top, and can also be fragments and are attached to the vessel in a different order, depending on the particular case.
- the number and slope of the ducts is calculated individually and at different heights of the ship, the ducts can be installed at different slopes and of different lengths.
- Air ducts are installed so that the air from the lower channel, rising gets into the next duct, which is higher and so on in turn until the end, until it rises to the surface of the water.
- Air ducts can be straight and arched or of another known shape, and on the sides of the vessel they are installed in horizontal rows, the distance between the rows is also different, in those cases when the external air ducts are laid on so that the front covers the next and so on to the stern (in the form of scales fish ajar and turned down).
- the upper row covers the bottom.
- the excess air is initially supplied to each duct so that the air immediately begins to rise not only along the channel, but also part of the excess air passes through the sides of the ducts and in turn passes all the ducts located above.
- the air ducts are narrowed so that the air gradually passes through the sides of the air ducts and maintains the air gap between the water and the vessel.
- the degree of narrowing depends on the particular case, taking into account the parameters: the amount of air supplied, the slope of the sides of the ship in that place, the width of the air channels, the distance between the ducts vertically and horizontally and the average speed of the ship.
- the air ducts from the front are wider and lower than the back (figure N ° 3).
- air vents are installed horizontally or with different slopes.
- the vessel can be built so that the tailgate has an appropriate slope and air presses on it, and the ship goes into the front, the slope of the air ducts on the rear side is different and is regulated at different speeds, by any ( known method. Flat metal ducts and different configurations.
- Air intakes are installed on the vessel from the bow above the waterline along the sides, which are connected to the compressor by air channels.
- the air intakes are installed so that air injection occurs from the front of the vessel, and so that it covers the entire volume of air that is encountered on the vessel’s path at any speed to provide forward traction and no headwind resistance.
- the air intakes can be of different types, and installed in different order.
- the vessel is lighter due to the pusher force of the air stream supplied by the air injector from the front and due to the air which presses the rear side up;
- Air ducts can be of different configurations, namely from a semicircular, corner, or from any other. Air ducts can be cut into the hull of the vessel, and the vessel can also be built with the appropriate profile, as well as air ducts can be adjustable in angle from horizontal in any known manner. The width and length of the ducts are also different and depends on the specific case.
- Air is supplied under the ship so as to partially free the ship from touching the water (lines and points).
- the air ducts of the upper row are constructed so that at the exit from the water the air path is directed backwards, so that the vessel pushes in front, and before exiting back and up to increase speed before exiting.
- the air separation channel is mechanically fixed horizontally in the middle of the bow, along the vessel’s contour at different heights of the front part which, in the water, on each air separation channel, several air injectors are installed, depending on the width of the vessel, with a direction parallel to the bow inclination or with a slight deviation in different directions so that the supplied air jets immediately spread over the entire area of the bow to relieve water resistance from the front and so that the zduha it passed under the vessel bottom.
- the air separation channel is installed at the beginning of the keel along the width of the bottom, and the injectors are directed back so that the air covers the bottom of the vessel completely from the front and so that when the vessel moves, air spreads over the entire bottom area, if necessary, the air separation channel with injectors can be installed and in other places along the length of the vessel, depending on the length of the vessel and speed.
- the ship is built with a wide flat or oval bottom, the bow of the vessel is tilted back starting from the waterline with different angles, and also wide.
- the ship can be provided with jet engines that are installed in the bow of the ship and connected to air intakes for pumping air from the bow of the ship to relieve the resistance of the oncoming air and to obtain traction force forward, and the nozzle directs air through the air duct and through the air separation channel with an injector air.
- the injectors direct a stream of air in front of the vessel and under the vessel, in front of the vessel the jet is directed into the water with an inclination down and back parallel to the inclination of the bow, or with a slight deviation in different directions and so that the air covers the entire height and width of the vessel in front, and so so that air space forms in front of the vessel at the moment when the vessel swims in there with the bow, to relieve water resistance.
- Air injectors can be installed in front of the vessel at different distances from the vessel, an elongated air separation channel that is mounted on a metal profile fixed to the bow of the vessel, horizontally lower than the bottom of the vessel and protrudes from the vessel forward of different lengths, at the end of which air injectors are fixed, so that the air stream is directed back to the side of the vessel below the level of the bottom of the vessel, so that the air rises and reaches the level at which the vessel goes and at that moment when the vessel enters there, for In order to create the low pressure in front of the ship, water resistance reduction front portion, the pressure of the jet pushes the ship forward.
- FIG. N Q 2 - bottom view of the vessel where:
- Fig. Y94 is a view of the vessel where the external injectors are installed in one row in the middle of the air separation channel, where:
- a vessel with a rounded duct is shown, with a wide top, rear view.

- FIG. Ne9 - shows a possible view of a high-speed vessel
- ⁇ . ⁇ 210 - shows a high-speed vessel from below, where
- the vessel operates as follows:
- Engines are launched to operate the air compressors (installed in a ship) that draw in air mass from the front of the vessel through the air intakes 9 and the vessel reaches forward, filling the air supply in the receivers (not shown), the control center monitors and regulates the air passage from the receivers through the check valves, the air passes through the air channels (not shown), the air separation channels 5 and through the injectors 4, a stream of air under the vessel is directed back and down, and pushes the vessel up and forward.
- Air injectors 7 which in the bow of the ship, also direct a stream of air into the water down and back almost parallel to the inclination of the bow of the ship, and push the ship up and forward, layers of air and air-water mass appear in front of the ship to the full height and width with low pressure, and the vessel stretches in front, the whole air mass under water pressure rises up and enters the air ducts 4 (external air channels), which are fixed along the sides of the vessel 8, and flow through the air ducts 4 up and back, pushing the vessel up and forward air x along the side of the vessel in the external ducts gradually passes through the sides (as the ducts narrow) and maintains an air gap between the vessel and the water.
- the air ducts 4 exitternal air channels
- the ship moves forward and catches up with the air mass from the front, the air supplied from the front of the ship is scattered across the entire surface of the ship from the front and enters the air ducts, adding pressure to the ship, which moves the ship forward.
- Air bubbles and lines appear between the vessel and the water, which, when the vessel moves, scatter, break, and spread throughout the entire outside area of the vessel, and the water resistance is reduced to a minimum.
- Air under water pressure goes up and down the air ducts and pushes the ship up and down.
- the air ducts do not resist forward movement when they are cut into the housing.
- the external air ducts are overhead, they are installed so that the front ones cover the following, like fish scales in the ajar and turned down from one to 89 degrees, and so on to the stern, for decrease in resistance, and if there is no distance between the rows, then the upper ones cover the lower ones.
- a portion of air is injected under the tailgate with injectors, and rising along the slope of the tailgate and pushing the ship forward, in the direction of travel, in the case when, after passing through the sides of the ship, air that did not have time to rise from the water enters under the backboard of the ship, where low pressure and raises the slope of the tailgate and adds pushing power.
- the pushing force is also decent and acts throughout the entire outer area of the vessel, which is in the water. And having put together all the contributing forces for the movement of the ship and a little resistance from the side of water and air to the ship.
- the vessel moves forward and is able to reach speed more than its predecessors and saves on fuel.
- air is also injected from the front of the vessel to remove the resistance of the oncoming air and to raise the traction force forward, and the air mass is supplied in front of the vessel and under the vessel with an inclination back and down to obtain a pushing force forward and upward, which facilitates the movement of the vessel, and to obtain an air gap between the vessel and the water and reduce the friction of water with the sides of the vessel.
- air separation channels 19 and 20 are installed at different heights of the vessel perpendicular to the length of the vessel in several rows depending on the length and speed of the vessel, and injectors 22 and 17 are installed so that air under the vessel is injected across the entire width of the bottom of the vessel and in front of the vessel the width of the bow and so that an air space is formed in front of the ship at the moment when the ship floats there, and so that air spreads along the sides of the ship to the full length to the stern to remove resistance I'm from the front of the ship and from the sides on the side.
- the air stream is directed backward or with a slight inclination in different directions, depending on the inclination of the bottom and through the air channels 18 it moves backwards and, due to the ovality of the bottom, passes along the sides and maintains the air gap between the vessel and the water, which results in an air cushion under the vessel for the whole the area on which it walks.
- High-speed vessels are built with elongated rear sides and tilts of the lower part towards the front so that the air mass that rises along the rear side and pushes the vessel up and forward.
