The non-watered hull is provided with channels for supercharging gas. The body is fulfilled in kits from needle-shaped elements with keeping after fixing these elements between themselves channels for supercharging gas with the aim of receiving stable bubbles of gas. The essence of the invention is in that reducing friction of water is achieved by maximum reducing of the value of moistened surface of the hull due to creation of a thin gaseous film-layer out of stable gas bubbles on the exterior surface of the hull. At that the water will slip on the surface of gas but not of the hull.

The mode of reducing hydrodynamic resistance is in that bending or longitudinal elastic vibrations of one and the same frequency with phase difference π/4 are excited on the non contacting with water surfaces of a transport vehicle or a pipeline. The longitudinal vibrations are excited in parallel to the movement of the transport vehicle in water or flow of liquid in a pipeline. The bending and longitudinal vibrations are mutually perpendicular , in connection with that in case of its presence the sections of the surface of the transport vehicle or of the pipeline make rotating movement along elliptical trajectories involving in the movement the frontier layer of the liquid with frequency vibrations. In technical constructions and in facilities of small sizes the mode is used with ultrasound frequencies.

Preliminary preparation comes to passing the second liquid through nozzle generating the gradient of axial velocity inside second liquid containing additive as mixture or in solution in order to turn, level along flow and elongate molecules of resistance-reducing agent. Ejector slot includes Koande surface as its part. Device proposed for realization of this method includes nozzle, vortex chamber and ejector. Proposed method makes it possible to exclude destruction and "blowing-off" of first liquid and to reduce diffusion rate of resistance-reducing agent in first liquid.

The invention relates to shipbuilding, namely to ship devices that use wave energy. One of the problems to be solved by modern science and technology is the problem of energy sources. Only one day on Earth is burned so much fuel organic origin, but nature can synthesize 1,000 years. However, the surface of the earth is 2/3 presents the seas and oceans, the energy of excitement which significantly exceed the reserves of fossil energy. The average condition of the seas and oceans is a condition in which anxiety is 3-4 points. Winds on the surface of the oceans is transferred to kinetic energy with a capacity of about 1011kW. Thousands of ships with crews aboard travel the seas and oceans, burning this fossil fuel, not noticing that their feet a huge amount of energy. From the time of the sailing of the fleet from two forces acting on the vessel, the pressure force of the wind caught the sails, and the power of the sea - the priority of the received first. Unnoticed the fact that the energy of the waves is much superior wind energy, since the density of water is 800 times the density of air. The loss of speed from the courts on the excitement reaches 50% [1], and doubling the speed would require a threefold increase in capacity of the main engine, and there is in the power of the waves, i.e. their energy passing through the width of the vessel per unit time during the course of the ship against the waves can be estimated by the expression
where ρ - the density of water; g - acceleration of gravity; a - wave amplitude; In - the width of a vessel; VcVp- ship speed and wave, respectively. This power outweighs the power of the main engine. Therefore, the use of wave energy is a promising direction receiving high speed of the vessel in waves. It remains to solve the technical problem of obtaining energy from sea waves. This is done using various technical devices[2], [3]. As a prototype we have chosen a device that uses wave energy to produce thrust [3], representing an additional bottom in the form of an inclined surface near the bow end of the vessel 1 (Fig 1). During rolling of the ship in waves, the force F has two components: the force N, which reduces the amplitude of pitching, which is beneficial to the habitat conditions of the crew, and the power of the T - additional traction force, which in the case of the main engine reduces its intensity, reducing the temperature of the cooling water and thereby increases motoresurs main engine. All this leads to a significant economic effect. In addition to this the th, in case of emergency (in case of ship grounding) additional bottom will prevent the destruction of the core bottom and the flow of water inside the hull. The aim of the present invention is to improve the construction of devices that will significantly increase the traction force and allows the ship to move yourself against waves without operation of the main engine. In emergency situations in case of failure of the main engine when you reserve time for repair or call a rescue vessel, this device will allow the vessel not only to reduce the drift velocity, but to move forward against the waves. This goal is achieved by the fact that the underwater part of the aft end of the vessel by means of brackets 2 (figure 1) is rigidly mounted stabilizer 3 in the form of a wing profile that more effectively communicate underwater hull of the vessel with the fluid flow in waves. The stabilizer does not extend past the dimensions of the vessel and is set at a small angle of attack α to the horizontal plane (figure 2), the optimal value of which will be installed in the process of experimental research. As shown by preliminary studies conducted on the Black sea in Sevastopol and in Koktebel, the stabilizer in the form aft of the wings of the second profile 3 (figure 1) in tandem with additional slope 1 has allowed more than two times to increase the speed of motion of the model against the waves. To prevent the action of cavitation and stall used wing profile with a uniform pressure distribution on the upper side of the wing (the side of the vacuum). One such profile is easily produced segment profile with a sharp incoming and outgoing edges. The bottom surface of the considerations of simplicity is flat. However, to ensure maximum quality and hydrodynamic lifting force of the lower surface can be made concave. Inclined surface in the area of the forward end of the underwater part of the ship and wing profile in the underwater part of the aft end of the work as a whole to form a fluid flow on a rampage in the area of the underwater part of the vessel so that is a smooth flow over the hull even during rolling, thus reducing the resistance of the hull and increased speed. Aft wing profile plays the role of a bearing surface, a thin, well-streamlined body that moves in a fluid with a low angle of attack α and which occurs hydrodynamic lift force L acting perpendicular to the direction of movement (figure 2). The lift force L is a component of the hydrodynamic force f, and the drag force D acts in the direction of negative values of velocity V of the progress of the vessel. In addition to snizeni the resistance movement of the vessel due to smooth around the body in the presence of the aft wing profile, the latter causes the lift force L acting on the shoulder, equal to the length of the vessel, to create differentbuy time, whereby the inclined surface 1 (Fig 1) more effectively communicates the excitement with fluid flow, increasing the force F and therefore its components: the force N and the traction force T, and hence the speed V of the vessel.
