The present invention relates to a marine jet propulsion systems, and more specifically to a water-jet propulsion systems (the MIC) and can be used as a stationary MIC or as a temporary MIC on self-propelled vessels. Recommended use as a stationary MIC.

Famous military-industrial complex, containing a combustion chamber and expansion (hydraulic chamber located below the water level, the selector valve to allow Assembly, fuel pump, injector, spark, air and exhaust system (Patent for invention "Engine" No. 2175620, application No. 2000110721/28, 28.04.2000, the Application for the invention "Jet engine" No. 2010146535/11, 15.11.2010,).

As a result of this structural embodiment of the disadvantages of this engine are:

- the design complexity;

- low efficiency.

The invention solves the following tasks: creation of marine military efficiency, as close as possible to the existing MIC, and a minimum number of mechanisms and systems.

This object is achieved in that:

the air in the combustion chamber during combustion of the fuel is under pressure, which provides a high pressure gas after combustion of the fuel, respectively, higher velocity water discharge, as well as complete fuel combustion;

The MIC consists of at least two propulsion that provides rawname the ing the work of the military-industrial complex, i.e. at steady state during water withdrawal and filling of the combustion chamber of one of the propeller thrust and the gas to the turbocharger creates a second mover;

- additional turbocharger actuator motor provides engine starting and power generation after launch;

- cooler provides cooling air after the turbocharger, which increases the mass of air supplied into the combustion chamber.

The above set of essential features is new and represents significant differences, which correspond to the criteria of the invention of novelty. Significant new features not known from the patent and technical literature.

Use the new essential features with the known characteristics of the prototype of the claimed invention, implements the task, and multiple times, which allows to conclude accordance with the present technical solution the criteria of the invention "industrial applicability".

Hereinafter the invention is explained in the description of specific examples of its implementation with reference to the accompanying drawings, on which:

figure 1 depicts the set of MIC Assembly, top view;

figure 2 depicts the set of MIC Assembly, side view;</>

figure 3 depicts a block diagram of the hardware MIC.

The MIC consists of the engine 1 (Fig 1), the air system 2, the gas supply system to the turbocharger 3, turbocharger 4, the evaporator 5, the exhaust system 6 and the motor (generator) 7.

The principle of the proposed MIC is as follows.

In the starting position of the expansion chamber, the MIC is filled with water. Electric motor driven turbocharger, blown and create excessive pressure in the combustion chamber of the first engine, then serves the fuel in the combustion chamber and an electric current to the spark plug. Next, open the bypass valve into the chamber to expand in the gas supply system on turbinegenerator. Gas under pressure is fed into the expansion chamber and the turbocharger, of the expansion chamber is ejected water, and turbocharger forces air into the combustion chamber of the second engine. Blown through the combustion chamber of the second engine, close the exhaust valve and raise the pressure in the combustion chamber, close the inlet valve of the second engine. After completion of the working cycle of the first motor is closed by-pass valve open exhaust valve and the inlet valve to the combustion chamber of the first engine. Serves fuel and electric current to the spark plug of the second engine is a flash, D. the more the sequence described above (re-cycle).

The advantages of this invention are:

- increase efficiency;

- reduction of cost;

- improving the reliability and technical resource.
