Method of increasing efficiency of fuel spray

FIELD: aircraft industry. SUBSTANCE: invention relates to aircraft engineering, particularly to methods of spraying different types of liquid hydrocarbon fuel and preparation of fuel-air mixture before combustion, and can be used in power supply systems of jet turbine, gas-turbine engines of internal combustion engines, Stirling engines, as well as in other power plants, for example in burners of boiler and power plants. According to method of increasing efficiency of fuel spray is created in flow of fuel in nozzle directly before its spinning uniform electric field and sharply non-uniform electric field on nozzle outlet of swirled fuel film and in swirling flow of air. EFFECT: uniform and sharply non-uniform electric field is created at same time, and in sharply non-uniform electric field is created in swirled fuel film and an air flow unipolar electric charge of same sign. 5 cl, 1 dwg, 3 tbl
