(57) Abstract: The invention relates to mechanical engineering and can be used to create water jets for example water jet ship propulsion. The method consists of heating the emitted through the channel or nozzle of the working fluid. And heating the working fluid is produced without changing its aggregate and phase state to a temperature above the saturation temperature of the liquid when the pressure of the environment into which occurs after the jet. When this channel or nozzle do with expanding output plot. The invention allows a significant increase in jet thrust flowing stream. The invention relates to mechanical engineering and can be used to create water jets for example water jet ship propulsion. Jet propulsion due to the extreme simplicity of design, reliability and the ability to work in shallow water are widely used to drive many types of marine vehicles. There is a method to create thrust in the ship the jet propulsion (analog) by release through the channel or nozzle side of the water using a Sipper water pump [1]. Fault is ΓΌ (cap) jet engine compared to the CP propeller at moderate speeds. Known taken as a prototype of the invention a method of increasing the thrust of a flowing stream by heat emitted through the channel or nozzle of the working fluid (water) hot gas [2]. According to this method, the hot gas and fresh water can be supplied to the nozzle alternately or continuously through the ejector using water as the entraining environment. Using the expansion of the compressed hot gas in the nozzle compared to [1] creates additional drag and increases the efficiency of jet propulsion. Achieved by the invention is a substantial increase in thrust of a flowing stream. This result is ensured by the fact that in the method of increasing the thrust of a flowing stream by heat emitted through the channel or nozzle of the working fluid according to the invention, the heating fluid is produced without changing its aggregate and phase state to a temperature above the saturation temperature of the liquid when the pressure of the environment into which occurs after the jet, and the channel or nozzle do with expanding output section. Heating the working fluid without changing its aggregate and phase state is realized is mennica or an electric heater (the mixture of the heated liquid hot gas excluded). Because working channel or nozzle pressure below the pressure of the heated fluid during movement along the channel or nozzle of the hot toward the fluid pressure comes the moment of equality of its temperature with the temperature of saturation at some intermediate pressure. The liquid thus instantly boils, and formed in a large number of pairs, extending in the nozzle with expanding output plot (a Laval nozzle), acquires considerable speed, resulting in a corresponding sharp (several times) to increase thrust of the jet, which was confirmed by experimental studies of the expiration of boiling water through the Laval nozzle. Example. At a temperature of 275oS, which corresponds to a pressure on the saturation line about 6 MPa (60 bar) the calculated value of thrust at the end of an incompressible fluid (water) through a short hole is about 3 H. For the same conditions at the end of boiling water through an expanding nozzle thrust is increased to approximately 11 H, i.e., 3.7 times. The change of the angle of expansion within 10-20olittle effect on the thrust nozzle. With increasing temperature from 225 to 325oWith the thrust increases from approximately 3 to 21 N, so E2. RF patent 2165375, 7, 63 N 11/09, 1999. Method of increasing the thrust of a flowing stream by heat emitted through the channel or nozzle of the working fluid, wherein heating the working fluid is produced without changing its aggregate and phase state to a temperature above the saturation temperature of the liquid when the pressure of the environment into which occurs after the jet, and the channel or nozzle do with expanding output plot.
