The invention relates to the hydrodynamics of water vehicles, namely concerns the design of liquid propellant rocket propulsion-propulsion complexes, including jet propellers for ships, underwater vehicles and other floating means. Can be applied to other modes of transport, pipeline transport, as well as for energy production. Aimed primarily at reducing the consumption of energy for transportation. Famous jet and ramjet gazovtomatika ship propulsion [1]. The acceleration of the water in the conduit or flow part of these propulsion is provided by a working body - axial pump (or propeller) or a centrifugal pump, and by using the energy of compressed air. The main disadvantage of this working body is the need of spending too much energy for his work. In addition, many of the jet propulsion motor shaft passes through the casing of the vessel and/or conduit. This increases the hydraulic resistance to the movement of water in the conduit propulsion decreases its efficiency. Known methods and devices to reduce fuel consumption by creating additional (Cabinet) thrust jet propellers. For this purpose, the conduit thruster set hydrodinamic the ski body, around which the water flow occurs Cabinet traction. The same result can be achieved by setting the corresponding hydrodynamic shape of the inner surface of the sheathing conduit propulsion [2-4 and others]. The disadvantage of these devices is relatively small decrease in energy at the constant speed of the vessel, a slight increase its efficiency, in General, high consumption of energy for the motion of the vessel. 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 in all cavities installed pressure sensors, and in the input and output jet nozzles - speed sensors [5]. The unit is adopted for the prototype. Disadvantages accelerator fluid - mostly can only be applied to accelerate the gas (air) under any regulations of the device 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 IP is Oldowan only when its vertical position, while the design of the accelerator symmetric about the vertical axis. In this case, in each transverse plane of the accelerator to the process of influencing the fluid, in particular, the process of ejection of the liquid from the cavity is uniform. When inclined to the vertical or horizontal location of the Central 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 a substantial reduction in energy costs for vessel movement (at least 70-80%), therefore, possible to improve the speed and/or distance, to reduce the fuel supply, to increase the efficiency of a jet-propulsion. The technical result is achieved by the fact that the accelerator fluid flow includes 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 fluid from the food to adjust the speed (power) at the output 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 input section, all cavities are installed pressure sensors, and in the input and output jet nozzles - speed sensors. According to the invention as a fluid medium is used, the fluid (liquid, gas, air). In the cavity, 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 cut off by a plane parallel to a plane passing through the Central axis of the device. The accelerator design is calculated on a defined maximum speed (power) of the fluid flow at the output. 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, changes in the amplitude and/or frequency of ionization of the fluid, and the electric is gidravlicheskogo strike in a fluid environment. The General scheme of the accelerator liquid shown in the drawing. Accelerator fluid flow contains placed coaxially with the nozzle 1 to the input section 2 and the critical-section 3, a nozzle 4 with a critical section 5 and the cavity 6 between the nozzles, then in the direction of the fluid follow the Laval nozzle 7 with a critical section 8 and the Laval nozzle 9 with a critical section 10 and the output nozzle 11. Between the nozzles 4 and 7 has a cavity 12 between the nozzles 7 and 9 is the cavity 13. When this nozzle 1 and 4, and 4 and 7, 7 and 9 are connected tightly. The cavities 6, 12, and 13 connected to the suction device 14 and feeding the fluid inside these cavities. In the cavity 6 placed blocks 15 ionization of the fluid and the valves 16 and electrodes 17, which are connected to the processing unit electro-shock (not shown). The sensors and the control unit also not shown. The device operates as follows. There are two ways to accelerator: using an external device to process the initial acceleration of the liquid in the accelerator and without it. In the presence of, for example, the pump is fed to the input of the accelerator fluid under pressure, and then it dispersed inside the accelerator. When the accelerator without external devices first connect the accelerator with the external environment (liquid). Cavity filled with fluid (and you receive oral airbags). Then hold the ionization of the fluid in the cavity 6 with the use of one or more means of ionization 15 placed in the cavity, and/or provide electrohydraulic shock of a certain amplitude and frequency between the electrodes 17 using block their formation. As a result of ionization and shock, the molecules and atoms of a liquid partially dissolved with evolution of a large amount of heat and kinetic energy [6]. When closed the valve 16, the flow of the expanded fluid (liquids and gases) in the cavity 6 crashes to the Central axis of the device, ejective this liquid from the external environment through the input section 2. Further, the valve 16 is opened and the cavity 13 is supplied fluid from the external environment or from the source of fluid. If necessary, make the suction of a fluid medium (liquid, gas) of the cavity 13. 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 operation of the accelerator. When the flow velocity of the fluid (liquid and gas)coming from the cavity 6, taking into account the ejected fluid through the nozzle 1) between sections 5 and 8, will be sufficient for ejection of fluid from the cavity 12, the latter will have some depression. It will increase the pressure differential between when the values 3 and 5, and thereby increase the speed of expiration and flow of fluid through the input section 2. This in turn will lead to the strengthening of the vacuum cavity 6. Such processes will occur as long as no longer to increase the degree of vacuum in the cavity. There are two possible outcomes. First, when the magnitude of the vacuum in the cavities 12 and 13 is not operated, then the flow rate will be greatest when technically possible degree of vacuum (due to samofokusirovke [7]). The second Exodus, when, on the contrary, the magnitude of the vacuum appoint and maintain in the cavities 12 and 13 artificially, the flow rate will be controlled. When establishing a constant flow rate at the exit of the accelerator 11 the ripple frequency is gradually reduced until complete shutdown. The accelerator starts to work only due to the suction in the nozzle 12 and 13 of the liquid from the external environment by a vacuum these cavities. After cessation of pulsation occurs the pressure in the cavity 6. If further evacuation cavities 6, 12, and 13 in the output nozzle 11 will have a steady stream of fluid. In this pump, the other external device to supply the fluid to the accelerator for acceleration, if it was used, disable. Adjusting the speed (power) of the fluid flow at the exit of the accelerator in real time is carried out by controlling the magnitude of the vacuum in the cavities 6, 12, and 13. For this purpose, a device 14 for collecting the fluid and supply tekokare in the cavity. Adjusting the speed (power) of the flow at the exit of the accelerator can be also carried out by changing the frequency of the pulsations of ionization of the fluid and/or electrohydraulic shock in the cavity 6. Finally, you can change the distance between the nozzles. To control the operation of the accelerator uses the readings of the pressure sensors placed in the cavities of the sensors of the flow velocity at the exit and entrance of the accelerator and indication device 14 received in the control unit of his work. The above mode of operation of propulsion is not the only one. The variant of the operation in which the flow in the cavity (injection) and the ionization of the fluid in the cavity 6, and the process of electro-shock in the fluid in the cavity are carried out continuously. In this case, the energy released by the decomposition of atoms and molecules of the fluid in the cavity 6, will complement, enhance energy effect movement of the fluid received from the vacuum cavities 12 and 13 of the accelerator. 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, the ionization of the fluid in the cavity 6, the implementation of electro-shock, compensation of friction losses and other Suction or flow of the fluid in the evacuated bands and, having small amounts, will require a relatively small amount of fuel. In addition, the energy consumed in the operation of the mechanisms of the opening-closing valve 16. Keeping the same set speed of the fluid flow (liquid to gas) at the output of the accelerator is mainly due to the vacuum in the cavities of the accelerator. Used sources of information 1.
