2 dwg

The invention relates to shipbuilding, namely the jet propulsion underwater vehicles (underwater vehicles, underwater vehicles and the like). Can also be used for surface vessels with relatively large draught aft bullboy.

Known water jet containing axial pump with vane impeller placed in the nozzle in the form of an annular wing aligned with the aft end of the vessel [1].

The disadvantages of similar - relatively large hydraulic resistance and low efficiency, high consumption of energy for the movement of the vessel.

Known water jet containing flow booster (pump)placed in the guide nozzle in the form of an annular wing aligned with the aft end of the vessel [2],which is taken as a prototype.

The disadvantages of the prototype - wide energy consumption for vessel motion, low compared with CP propeller efficiency.

Known accelerator fluid medium containing at least two nozzles on the same axis, with at least one nozzle rigidly or with the possibility of axial movement coaxially introduced in next in the direction of the fluid nozzle to form between the nozzle cavity, and at least one cavity in communication with the feed devices and suction of the fluid in at least one cavity posted by means of ionization of the fluid into all the cavities installed pressure sensors, and in the input and output jet nozzles - speed sensors [3].

Disadvantages accelerator fluid - mainly the accelerator can only be applied to accelerate the gas (air) in any of its positions in space. At the same time, to accelerate the movement of liquid (water, mixtures of water with gases, petroleum products, etc.) the design of the accelerator gas (air) can be used only for vertical placement and symmetry relative to the vertical axis. Then in each transverse plane of the accelerator to the process of influencing the fluid, in particular, the process of ejection of the fluid from the cavity is uniform. When inclined to the vertical or horizontal arrangement of the axis of the accelerator, the liquid tends to fill all located at the bottom of the volume, the symmetry of the processes influencing the fluid is disturbed. To create evacuated cavity in the upper part of the device is much easier than at the bottom. Design acceleration gas to accelerate fluid is irrational.

The technical result of the invention is to substantially reduce the flow of hydrocarbon fuel (not less than 70-80%) in the absence of a shaft passing through the hull of the vessel and/or covering of the conduit, the hydraulic resistance reduction, increased efficiency propulsion.

The technical result is achieved by the fact that Odom the private propulsion underwater vessel contains in the guide nozzle coaxially with the feed end of the vessel accelerator of the fluid flow, comprising at least two sealed between a nozzle at one axis, with at least one nozzle rigidly or with the possibility of axial movement coaxially introduced in next in the direction of the fluid nozzle to form between the nozzle cavity, and at least one cavity in communication with the feed devices and suction of the fluid to adjust the speed on the output or capacity of the accelerator, at least one cavity posted by means of ionization of the fluid, providing its ionization in the cavity and the movement of the accelerator with the ejection of the fluid through the inlet section of the guide nozzle in all cavities installed pressure sensors, and in the input and output jet nozzles - speed sensors. According to the invention as a fluid medium adopted a mixture of water and gases (air) in the propulsion is used, at least one accelerator. In the cavity of the accelerator, which provides the suction and supply of a fluid medium, optionally placed electrodes for implementation in fluid electrohydraulic shock. When the accelerator is equipped with a set of electro-shock, the outputs of which are connected with the electrodes. The accelerator can be placed horizontally, and well-known symmetrical design of the accelerator gas flow (air) is used only the top part, clip horizontal plane parallel to a plane passing through the Central axis of the device. The accelerator design is calculated to set the maximum flow rate at the outlet or set the power. In this case, smaller velocity values are obtained by varying the magnitude of the vacuum in the cavities with drawers and suction of the fluid, and also due to changes in the amplitude and/or frequency of ionization of the fluid, as well as electro-shock fluid in the cavity.

Schematically, the invention depicted in figure 1 (shown in the General scheme of the accelerator and the stern of the vessel), figure 2 presents the scheme of the accelerator.

Water jet underwater vessel (figure 1) consists of directing the nozzle 1 at the stern of the vessel 2, input 3 and output 4 hole and accelerator of the fluid flow 5.

The accelerator of the fluid flow (in the General case, the mixture of water and gases) (figure 2) contains placed coaxial nozzle 6 to the input section 7, and the critical-section 8, the upper part of the nozzle 9 with a critical section 10 and the cavity 11 between the nozzles. In the cavity 11 placed blocks 12 ionization of the fluid 12, the electrode 13 forming unit electro-shock (not shown) and the valve 14. Next in the direction of the fluid follow the Laval nozzle 15 with a critical section 16 is a Laval nozzle 17 with a critical section 18 and outlet nozzle 19. Between the nozzles 9 and 15 has a cavity 20 between the Laval nozzles 15 and 17 of the cavity 21. When this nozzle 6 and 9, 9 and 15, 15 and 17 are connected tightly. The cavities 11, 20 and 21 connected device 22 of the suction and supply of the fluid inside these cavities. The sensors and the control unit not shown.

The device operates as follows. Pre-accelerator 5 is filled with water (you might have air bags). There are two ways to start accelerator: using an external compressor fluid under pressure and without it. In the first case injected into the accelerator fluid should have a speed sufficient for the subsequent samofokusirovke [5] accelerator. The latter depends on the design of the accelerator. In the second case, produce ionization of water in the cavity 11 with the use of one or more means of ionization 12, including using electrodes 13 forming unit electrohydraulic shock of a certain amplitude and frequency. As a result of ionization and shock, the molecules and atoms of the fluid (here, water and possibly air) partially dissolved with evolution of a large amount of heat and kinetic energy [4]. With closed valves 14 stream is expanded in the cavity 11 of the fluid (water and gas) is ejected toward the Central axis of the device, ejective while C is Portnoy water through the input section 3. Further, the valve 14 is opened and the cavity 11 is supplied fluid (sea water or air). If necessary, make the suction of water and gases from the cavity. After that the valves are closed. The frequency of such operations (ripple) is regulated and may be high enough to provide quasi-continuous nature of the work. When the flow velocity of the fluid (water and gas)coming from the cavity 11, taking into account the ejected overboard water through the nozzle 3) between the sections 10 and 16 will be sufficient for ejection of water from the cavity 20 in the past will have some depression. It will increase the pressure differential between the sections 8 and 10 and thereby increase the speed of expiration and flow of sea water through the inlet section 8. This in turn will lead to increased vacuum cavity 20. Such processes will occur as long as no longer to increase the degree of vacuum in the cavity. With regard to the issue of control of operation of the accelerator, two things can happen. First, when the magnitude of the vacuum in the cavities 20 and 21 is not operated, then the flow rate will be greatest when technically possible degree of vacuum (due to samofokusirovke [5]). The second option, when, on the contrary, the magnitude of the vacuum appoint and maintain in the cavities 20 and 21 artificially, the flow rate will be controlled. Oppo is icno and in relation to the cavity 11. When establishing a constant flow rate in the accelerator 5 frequency pulsations (ionization) in the cavity 11 is gradually reduced until complete shutdown. The accelerator and drives in General are starting to work only due to the suction in the nozzle 20 and 21 of the fluid (sea water) through the hole 3 by the vacuum of these cavities. After cessation of pulsation occurs the pressure in the cavity 11. When the vacuum cavities 11, 20 and 21 in the output nozzle 19 will have persistent jet stream of fluid (mostly water)that creates thrust of the vessel. A pump or other external device to disperse the fluid in the accelerator (accelerator) thruster off.

Adjusting the speed (power) of the fluid flow at the exit of the thruster (accelerator) in real time in the first place is by controlling the magnitude of the vacuum in the cavities 11, 20, 21. For this purpose, a device 22 for exhaust fluid (gases, for example air) and supply (injection) of fluid (water, air). Adjusting the flow rate at the output of the propulsion engine (accelerator) may be implemented and/or by changing the amplitude and frequency of pulsation of the process of ionization of the fluid in the cavity 11, and the process of electro-shock in a fluid environment. To control the operation of the accelerator uses the readings of the pressure sensors, rasmusen the x in the cavities, sensors flow velocity at the exit and entrance of the accelerator, as well as indications of the devices 22 received in the control unit by operation of the accelerator.

The above mode of operation of the accelerator is not the only one. Possible variant in which the feed (injection or suction of fluid in the cavity and/or manufacture of electro-hydraulic shock in the fluid cavity 11 is carried out continuously. In this case, the energy released by the decomposition of molecules and atoms of fluid (water and gas) in the cavity 11 will complement, enhance energy effect movement of the fluid in the accelerator obtained only from vacuum cavities 11, 20 and 21.

The energy costs of accelerator operation is relatively small. Energy is spent on the initial acceleration of the fluid inside the accelerator to the target speed, including the ionization of a fluid medium and the process of electro-shock in the fluid in the cavity 11, and compensation of hydraulic losses in the accelerator, etc. in Addition, the energy consumed in the operation of the mechanisms of the opening-closing valve 14, and the device 22. Keeping the same set of jet velocity at the exit of the thruster is mainly due to the vacuum in the cavities of the accelerator.

The technical result of the invention is a substantial reduction in the energy costs of movement is their vessel (70-80%), therefore, the ability to increase the speed and/or distance, to reduce the fuel supply, to increase the efficiency of propulsion.
