Description

The invention relates to the field of engineering, in particular to gas turbine engines, and can be used in engine building.

A gas turbine engine is known in which oxygen contained in atmospheric air is used to burn fuel. The main elements of the engine are a compressor, a combustion chamber and a gas turbine / Borgest N.M. et al. A Brief Dictionary of Aviation Terms. - M .: Publishing House of the Moscow Aviation Institute, 1992, pp. 44-45 / [1].

A disadvantage of the known engine is low economic, environmental efficiency in operation.

Closest to the proposed invention is a gas turbine engine containing an input device, an axial compressor with guides and rotor blades, a combustion chamber, a fuel supply system, an ignition device, a turbine and an exhaust device / A.c. THE USSR. No. 1329280, F02K 3/00, 04/30/1992, / [2].

The disadvantage of the prototype engine is the high operating costs of fuel and high toxicity of exhaust gases.

The technical problem solved by the invention is to increase the operational efficiency of a gas turbine engine.

The problem is solved in that in a gas turbine engine containing an input device, an axial compressor with guides and rotor blades, a combustion chamber, a fuel supply system, an igniter, a turbine and an exhaust device, an input device and an axial compressor with guides and rotor blades are equipped with electrolyzers. Electrodes of electrolyzers with the possibility of free passage through them of an air stream and dissociation of water / decomposition of water into hydrogen and oxygen / naturally present in the air, and additionally, for example, with a nozzle of an electrolyte / aqueous electrolyte solution introduced into the air stream / when an electric current passes, for example , supplied from an onboard DC source, respectively installed in the input device and made on the guide and working blades of the axial compressor. In this case, the electrodes of the electrolyzer of the input device are made, for example, of a nickel mesh.

The invention is shown in the drawing.

The gas turbine engine contains an input device 1, an axial compressor 2 with guides 3 and working 4 blades, a combustion chamber 5, a fuel supply system 6, an ignition device 7, a turbine 8 and an exhaust device 9. The input device and an axial compressor with guides and working blades are equipped with electrolyzers respectively 10 and 11. Electrodes 12 and 13 of electrolyzers with the possibility of free passage through them of an air stream and dissociation of water / decomposition of water into hydrogen and oxygen /, naturally present in the air / water vapor /, and additionally, for example, with a nozzle 14 of an electrolyte introduced into the air stream / an aqueous electrolyte solution / when an electric current passes, for example, supplied along lines A and B from an onboard DC source / not shown /, respectively, are installed in the input device and are made on guide and working vanes of the axial compressor. In this case, the electrodes 12 and 13 of the electrolyzer 10 are made, for example, of a nickel mesh.

The gas turbine engine operates as follows.

Before starting the engine into operation, electrodes 12 and 13 of electrolyzers 10 and 11, along lines A and B, from the on-board source / not shown / supply direct current. Then the starting device untwist the rotor of the engine. The operation of the guides 3 and the working 4 blades of the axial compressor 2, atmospheric air through the inlet 1 is sucked into the engine. The air flow, with the natural way the water vapor present in it and additionally, for example, nozzle 14 introduced into it and sprayed with the same nozzle electrolyte, for example, an aqueous solution of caustic potassium, first enters the cell 10, where water vapor due to the passage of direct current partially dissociates. Further, the air flow enters the electrolyzer 11, where it is compressed by the operation of the guides 3 and the working 4 blades of the axial compressor 2, and during compression, again due to the passage of direct current, the water vapor finally dissociates. Enriched with hydrogen and oxygen, the compressed air then enters the combustion chamber 5, where fuel is also supplied by the fuel supply system 6. The resulting air-fuel-rich mixture of hydrogen and oxygen is ignited using an ignition device 7. Further, the combustion products, performing useful work, expand in the turbine 8 and are discharged through the exhaust device 9 into the atmosphere.

The proposed gas turbine engine in operation is economical and environmentally friendly. Will find application in engine building.
