(57) Abstract: The invention relates to shipbuilding, in particular to tools for creating thrust hydro jet propulsion of the vessel. The way to create traction hydro jet propulsion vessel includes alternate filling at least two working chambers with water due to the velocity head of its external thread, filling alternates with alternate supply in water-filled chamber gas under pressure. Under the sequential emptying of the working chambers are created pulses hydro jet thrust. When the flow in the working chamber of the gas creates a water hammer in to fill them with water. Excess gas pressure in the process of filing support is directly proportional to the product of the fourth power of the desired velocity of water discharge from the nozzle hydro jet propulsion for the second degree of relationship duration of gas supply to the length of the flow part of the engine on the water. This ratio is directly proportional to the ratio of the square root of the excess pressure gas supplied to the second degree of the desired velocity of water discharge from the nozzle. Improved pulsed thrust hydro jet propulsion. 1 C.p. f-crystals, 1 Il. The invention relates to a liquid re is operating in the liquid column, mostly, when ignited, the gas or vapor mixture. The prior art. Jet thrust that is created by the pulses of gas pressure can be significantly higher than when using gas as a continuous ejecting environment, in the invention with the U.S. patent N 5,598,700. The use of pulse pressure gas can be implemented just as it is provided by the RF patent N 2050307. The greatest effect of the use of pulse pressure gas can be achieved, if the way to create traction hydro jet propulsion vessel includes alternate filling at least two working chambers of the engine water due to the velocity head of its external thread, striped with alternate supply in water-filled chamber gas under pressure, and the creation of pulses hydro jet thrust under the sequential emptying of the working chambers, as provided by the invention on the author's certificate USSR N 508440. However, in this case not implemented all the possibilities of increasing engine thrust. The inventionThe basis of the invention is the creation of high impul the corresponding pressure of water hammer. To solve this problem, a method of creating a thrust hydro jet propulsion of the vessel, including alternate filling, at least two working chambers of the engine water due to the velocity head of its external thread, striped with alternate supply in water-filled chamber gas under pressure, and the creation of pulses hydro jet thrust under the sequential emptying of the working chambers, characterized in that it provides that, upon application to the working chamber of the gas creates a water hammer in to fill them with water, which excess gas pressure in the process of filing support is directly proportional to approximately the product of the fourth power of the desired velocity of water discharge from the nozzle hydro jet propulsion in the second degree is the square of the ratio of the duration of the gas supply to the length of the flow part of the engine on the water, despite the fact that this ratio is directly proportional to the ratio of, approximately, of the square root of the excess pressure gas supplied to the second degree to the square of the desired velocity of water discharge from the nozzle hydro jet propulsion. At this speed the expiry of the pressure of the water column is: H = (V/ )21/2g where =0,8-0,9 - beserkley, corresponds to the pressure of the water column. H0= V4/g ( /L)2C, where H0the pressure corresponding to the pressure of the gas in the working chamber of the engine, - the duration of the gas in the working chamber, L is the length of the flow part of the engine on the water, C = 0,06-0,12 - dimensionless coefficient of proportionality. The rate of water discharge from the nozzle of the thruster is greater, the smaller the ratio L/a, where , where a0- the speed of propagation of sound in water, D - given inner diameter of the water supply from the working chamber to the nozzle thruster, K - bulk modulus of water, the wall thickness of the water, E - the modulus of elasticity of the material of the water. Preferably, if the excess pressure in the working chambers create a frequency from 1 to 10 Hz. Depending on the magnitude of the pulses hydro jet thrust and their frequencies are given a required thrust propulsion. The invention is further illustrated by the specific embodiments thereof with reference to the accompanying drawing depicting the engine with the propeller, implement patented method. Information confirming the possibility of izobreteniya are shared valve device 3 and the working chambers 4 and 5, communicated between a cavity water nozzles of the ejector 6. The combustion chambers 7 and 8 are connected to check valves 9, 10 and adjustable air-gas ejector-mixer 11 with the container 12 filled with liquefied gas under pressure. At the exit of the combustion chambers 7 and 8 are installed reflectors 13 and 14. Vent pipes 15 and 16 is connected to the exhaust pipe 17 and the nozzles 18, 19 and the valve-rams 20, 21, which are connected articulated rocker arm 22 with the magneto rotor 23 system electrosurgery. The latter has the spark plugs 24 and 25 located in the combustion chambers 7 and 8. The gas coming from the cylinder 12, is mixed in the ejector-mixer 11 with air in a predetermined ratio and fed into the combustion chamber 7, where the fuel mixture is ignited by the spark plug 24. The products of combustion are emitted into the working chamber 4 and when closed, the valve-RAM (20 displace located in the working chamber 4 of the water column through the inner profiled tube 1, thereby creating a pulse jet thrust. While the Central part of the valve device 3 closes the pipe section 1. Coming out of the camera 7 and the combustion products afterburned and swinging the reflector 13, and part of the water displaced from the working chamber 4, when the SIP is th peripheral part of the valve device 3. This uses the velocity head of the water when the vessel. At this time, the combustion chamber 8 is filled with the fuel mixture and the working chamber 5 with the water. The combustion products from the previous cycle is removed through a vent pipe 16, valve is open-RAM 21 and the exhaust pipe 17. Upon filling of the working chamber 5 water enters the vent pipe 16 and the valve is closed-RAM 21. In this part of the water through a nozzle 19 is sprayed on the hot in the previous cycle reflector 14 and, turning to steam, together with moving up in the working chamber of the water piston compresses the fuel mixture in the combustion chamber 8. Upon closure of the valve; a battering-RAM 21 on the contacts of the spark plug 25 is supplied with a high voltage from the magnet 23. The fuel mixture in the chamber, the combustion chamber 8 is ignited, as in the first working circuit starts blowing and filling of the working chamber 4 water and the combustion chamber 7 of the fuel mixture. Synchronous operation the valve-battering rams 20 and 21 together with the system electronicAsia 5 provides a consistent repetition of cycles in both working paths. Thus, it is an alternate filling at least two working chambers 4 and 5 of the engine water due skorostnym pressure, and creating pulses hydro jet thrust under the sequential emptying of the working chambers with a frequency of from 1 to 10 Hz. When filing in the working chambers 4 and 5 gas create water hammer in to fill them with water. Excess gas pressure in the process of filing support is directly proportional approximately to the product of the fourth power of the desired velocity of water discharge from the nozzles of the pipes 1 and 2 in the second degree is the square of the ratio of the duration of the gas supply to the length of the flow part of the engine on the water. This ratio is directly proportional to the ratio of, approximately, of the square root of the excess pressure gas supplied to the second degree to the square of the velocity of water discharge from the nozzles of the pipes 1 and 2, as shown in the section "summary of the invention". 1.
