The invention relates to aircraft engine industry, in particular for gas turbine engines, and can be widely used in engines for various purposes.

Known gas turbine engine (GTE) - thermal machine designed to convert energy of combustion into kinetic energy of the jet stream and (or) mechanical work on the motor shaft. The main elements of the CCD are the compressor, the combustor and the gas turbine. Uses fuel oil. (Largest N.M. and other Short dictionary of aviation terms. - M.: Izd-vo MAI, 1992) [1].

The disadvantages of this engine are high operating costs for fuel oil and high toxicity of exhaust gases.

Closest to the proposed invention is a gas turbine engine, comprising a housing and placed in it the shaft, the compressor with the guides and the rotor blades, a combustion chamber with flame tube and igniting device, the turbine with deployme and the rotor blades and the preparation system and fuel supply. For operation of the engine used oil fuel (A.S. USSR, No. 1329280, F 02 K 3/00, 30.04.1992,) [2].

The disadvantage of the closest analogue is the high operating costs for fuel oil and high toxicity of exhaust gases. The technical problem to be solved by offering the first invention, is to increase economic efficiency and environmental cleanliness of the engine in operation.

The problem is solved in that in the gas turbine engine, comprising a housing and placed in it the shaft, the compressor with the guides and the rotor blades, a combustion chamber with flame tube and igniting device, the turbine with deployme and the rotor blades and the preparation system and fuel supply, the body is made with a sealing its entrance cover, for example, mounted on bolts. Cooking system and fuel supply is made in the form of the cell, with liner DC voltage to its electrodes, a free passage through it of the electrolyte (aqueous solution of electrolyte, for example an aqueous solution of caustic potassium and decomposition products of water while passing direct electric current through an electrolyte that is installed before the compressor in a sealed part of the body. Moreover, the pumping device, for example, plunger, injector cooking and fuel is made to flow and atomization of the electrolyte in the electrolyzer. Thus the cell can be made either of metal with holes, for example, from Nickel sheet or may be made of wire mesh, for example of Nickel, in the form of two electrodes-Polupanov, its elements with a gap wpisy is relating to each other. The nozzle may have a cavitator, made in the form of local necking her channel.

The essence of the invention shown in the drawing, in which figure 1 is an engine that converts the energy of combustion of the fuel in the work on the shaft; figure 2 - energy of the jet stream.

An example of implementation of the proposed solution. Gas turbine engine includes a housing 1 (1-2) with sealing its entrance cap 2, for example, mounted on the bolt 3, and placed in it the shaft 4, the compressor with the guides 5 and 6 working blades, a combustion chamber 7 with the flame tube and igniting device 8, a turbine with deployme 9 and 10 working blades. Cooking system and fuel supply is made in the form of electrolytic cell 11 with eyeliner constant electric current to its electrodes, a free passage through it of the electrolyte (aqueous electrolyte) and the decomposition products of water during the flow of direct current through the electrolyte, mounted in front of the compressor in a sealed part of the body. Moreover, the pumping device, such as a plunger (not shown), and the nozzle 12 is made to flow and atomization of the electrolyte, for example an aqueous solution of caustic potassium into the cell. Thus the cell can be made either of metal with holes (not shown), either of metal mesh in the form of two electrodes-Polupanov 13 and 14, its the mi elements 15 with a gap 16 fit into each other. The nozzle may have a cavitator (not shown)made in the form of local necking her channel.

Gas turbine engine operates as follows. Before starting the engine on the electrodes-semiblocks 13 and 14 of the electrolyzer 11 serves DC. The work of the guides 5 and 6 working of compressor blades in a sealed cover 2 of the housing 1 in a vacuum. Pumping device (not shown) through the nozzle 12 with the cavitator local narrowing of the channel (not shown) under pressure, for example, 2 MPa, delivers the electrolyte, for example an aqueous solution of caustic potassium into the cell 11. In the cavitator nozzle 12 is to increase the speed of the electrolyte and the pressure drops to a critical value leads to dissociation and subtlest atomization of droplets of electrolyte in the cell 4. Then sprayed electrolyte passes freely through electrodes-semiblocks 13 and 14 of the cell, for example, from a grid made and due to flow through the electrolyte DC leads to the decomposition of water into hydrogen and oxygen. In this case, the decomposition of water into oxygen and hydrogen is subjected to a small part of the electrolyte, the rest of it turns into water vapor. The resulting decomposition products water guides 5 and 6 working blades of the compressor is compressed and fed into the combustion chamber 7. Received into the combustion chamber 7 bodoro the but-oxygen mixture is ignited by an igniting device 8. Further, the combustion products are expanded in the nozzle 9 and 10 working turbine blades, doing the work.
