An example of implementation of the proposed solution.

Gas turbine engine includes a housing 1 /see drawing/ sealing its entrance cap 2, removable attached to the bolts 3 and placed in it the shaft 4. System preparation and supply of fuel, in the form of electrolytic cell 5, consisting of electrodes 6 and 7, with the possibility of permanent eyeliner electric current, free passage through them of the electrolyte, for example, by executing them from the Nickel mesh installed before the compressor in a sealed part of the body and electrodes formed by the liner, a constant electric current to the rails 8 and work 9 to the compressor blades 10 on lines a and B. Moreover, the pumping device /not shown/ and the nozzle 11 of the system of preparation and supply of fuel is made to flow and atomization of the electrolyte in the electrolyzer and the burner when this may have cavitator local narrowing her channel /not shown/.

Gas turbine engine operates as follows.

Before starting the engine for the electrolyzer 5, consisting of electrodes 6 and 7 and out of the guides 8 and working 9 blades of the compressor 10 by lines a and B serves a constant electric current. The work of the guides 8 and working 9 blades of the compressor 10 in a sealed cover 2 of the housing 1 in a vacuum. Pumping device /not shown/, for example, plunger, through the nozzle 11 with the cavitator in the form of local necking her channel /not shown/, under pressure, for example, 2 MPa delivers the electrolyte, for example, an aqueous solution of caustic potassium into the cell 5. In the cavitator nozzle 11 due to the pressure drop and increase the speed of the electrolyte leads to dissociation and subtlest atomization of droplets of electrolyte in the electrolytic cell 5. Then sprayed electrolyte passes freely through, for example, of Nickel mesh made electrodes 6 and 7 and by leakage through the electrolyte constant electric current causes electrolysis is the decomposition of water into hydrogen and oxygen. Then this mixture, the guides 8 and work 9 blades of the compressor 10 is compressed and, due to the constant flow of electric current through the electrolyte leads to the electrolysis of water. The decomposition of water into oxygen and hydrogen is subjected to a small part of the electrolyte, the rest of it n eurosets in water vapor. Due to the fact that in the presence of water vapour, hydrogen and oxygen are slightly impossible explosion of detonating gas in the compressor. Obtained in the electrolytic cell 5 and compressed in the compressor 10 of the hydrogen-oxygen mixture flows into the combustion chamber 12. Received into the combustion chamber 12, the mixture is ignited by an igniting device 13. Further, the combustion products are expanded in the nozzle 14 and 15 working turbine blades, doing the work.
