(57) Abstract: The invention relates to shipbuilding, in particular to the ship's engines with water-gas jet propulsion. Propulsion-propulsion system provides end-to-end vodoprovodny channel (1), the axis of which is located the motor housing (2). The cavity of the housing separated by a piston (3) into two chambers; a compressed gas and combustion (In). On the opposite ends of the piston is resiliently mounted two rod (6, 7) with valves (8, 9) for blocking the inlet of the diffuser (10) and outlet nozzle (11). The inlet valve (8) is triggered ahead of the outlet (9), blocking the inlet diffuser and the outlet valve (9) opens with a time delay, and excessive pressure in the combustion chamber (C) pushes the fluid from vodoprovodnogo channel through the output nozzle that allows you to increase performance, simplify design and increase the reliability of the system. 2 C. p. F.-ly, 3 ill. The invention relates to shipbuilding, in particular to the ship's engines with water-gas jet propulsion instead of a marine diesel engine with a generator and propellers with electric motors. The invention can find application for any marine and river vessels benzeneamine vehicles. The accepted prototype and stated the object of the present invention have a number of common characteristics. These include: how to create thrust by pushing from the propulsion of the water column high-pressure gas, propulsion, cooling system of the combustion chamber, the combustion chamber with the valves of the injection of fuel and oxidant, electric candle, the valve of release of gases from the combustion chamber [1] . The disadvantage of the prototype is: a high degree of design complexity and consequently the low reliability, the complexity of the seal rotary valves, fill thruster running water through the side window, the cooling system of the combustion chamber, low fill rate mover running water. The objective of the invention is to increase the speed of the engine propulsion system, simplify the design and increase reliability. The task is implemented as follows. Propulsion-propulsion system provides end-to-end vodoprovodny channel, the axis of which is located a combustion chamber. The cavity of the combustion chamber divided by the piston into two different size volume - direct the combustion chamber and the volume of compressed gas to control the operation of degenekratiya water flow through the channel and the release of high pressure gases from the combustion chamber. Valve stems connected with the piston via elastic elements. Cooling of the combustion chamber is carried out by flowing water contained in the cone of the complex. These characteristics have been identified in other technical solutions in the study of the level of the art and, therefore, the decision is novel and involves an inventive step. In Fig. 1 shows a motor-propulsion system with one thruster of Fig.2 is a diagram of the forces on the piston of the combustion chamber of the engine of Fig.3 - motor-propulsion system with multiple drivers. The complex consists of several drivers, each of which is made in the form of through-axisymmetric vodoprovodnogo channel 1, inside of which the axis is located in the motor housing 2, connecting with the walls of the channels using pylons. Engine 2 is divided by the piston 3 into two different-sized volume: a - compressed gas chamber and the combustion chamber. To the opposite sides of the piston 3 through the elastic elements 4 and 5 attached two rod 6 and 7 valves 8 and 9. The valve 8 is an inlet valve cone 10 and is designed to overlap the inlet of the diffuser. The exhaust valve 9 of the combustion chamber is used to reset botoi propulsion-propulsion complex and before starting the engine is filled with compressed gas. The magnitude of this pressure may vary within wide limits and defines the power of the engine. The amount of In - directly the combustion chamber contains a window of injection of fuel and oxidant, an electric spark to ignite the mixture. The channel of the diffuser before the valve 8 on the perimeter has a system of holes 12 communicating with the outer surface of the complex and intended for water flow through the channel of the diffuser with a closed valve 8 in order to reduce drag during movement. The nozzle 11 vodoprovodnogo channel output is divided into two parts 13, 14 facing surface of the tail part of the complex at a small angle to the axis vodoprovodnogo channel. Weekend openings plane elastic plates 15, 16 to prevent entrainment of water into an engine after completion of the working cycle. The complex is as follows. In the initial state vodoprovodny channel filled with water, in the chamber of compressed gas has a pressure of compressed gas for closing the outlet of the combustion chamber valve 9 and prevent the ingress of water. When this position of the piston valve cone 8 is open. The combustion chamber is filled gt;FB(see Fig.2). It is evident from Fig.2 shows that this condition is fulfilled when the pressure PA=PBbecause both ends of the piston have different surface exposed to the pressure from the volume of the a - ring, which is limited by the diameter of the piston and stem diameters, from In - ring, limited by the diameter of the piston and the diameter of the sealing band exhaust valve. In this condition of excessive force by volume And securely holds the valve 9 in the closed position. The ignition of the fuel and oxidant is a rapid increase in pressure and temperature in the combustion chamber, this will disturb the balance of forces acting on the piston: FB>FA. When the piston begins to shift to the left, compressing the elastic element 5, connecting it to the stem 7 of the valve discharge pressure of the combustion chamber. At the same time moves the rod 6 with the valve 8 to close the inlet of the diffuser. At that time, when the elastic element 5 is compressed and the piston will come into hard contact with the valve stem 9, will close the valve 8 of the cone and the opening of the valve 9. When the gas in the combustion chamber, through the gap will be on the opposite side of the valve 9 and to balance the combustion chamber. Simultaneously, the piston will reliably seal the inlet of the diffuser valve 8. The increase in the pressure in the channel after the valve cone will lead to additional seal valve and release water column from the nozzle 11 of the thruster. When this elastic plate valves 15, 16 automatically opens under the influence of water pressure in the thruster. Will be rapid discharge of water from the propeller and automatic closing of the reed valve 15, 16 due to the elasticity. As the pressure drop of the gas in the propulsion part of the complex will be a point where FA>FB. Will start the movement of the piston to the right, leading to the closure of the exhaust valve of the combustion chamber and the opening of the valve cone. While the valve of the pressure relief is in hard contact with the piston and starts moving in the closing direction. The rod 6 with the valve 8 of the diffuser is in elastic contact with the piston and remains in place until the time of closing the exhaust valve 9, as in the channel there is excess pressure, holding the inlet valve 8 of the cone in the closed state. When the value of this pressure will decrease to a certain level, the valve 8 will be opened under the influence of elastic elementeita. Increasing the pressure in the vessel, it is possible to increase the pressure of the mixture of fuel and oxidant supplied to the combustion chamber, and thereby to increase engine power. Control motor-propulsion complex is carried out using the controller on the information received from the pressure sensors installed in the camera, and at the end of the propulsion system. One of the examples (see Fig. 3) layout of the propulsion-propulsion complex, consisting of five engines. Each of the motor drivers are included in the work alternately, after the completion of the operating cycle of one of them. In this case, the diffuser is divided into five channels, each of which axis is located in the combustion chamber. The source of information1. RF patent 2003587, 63 N 11/00, 1985 - prototype. 1.

The method of operation of motor-propulsion of the ship under item 1, comprising receiving impulse alternately in each of these engine-propulsion complex, characterized in that in the chamber of compressed gas and combustion creates a proportional pressure, then ignite the fuel mixture in the combustion chamber with the formation of excess pressure acting on the piston that moves through the stem of the valve while the intake valve is triggered ahead of graduation, blocking the entrance cone of the propeller and the exhaust valve is opened with a time delay, pushing the fluid from vodoprovodnogo channel through the output nozzle.
