FIELD: electric engineering, possible use for engineering electric power systems for aircrafts. ^ SUBSTANCE: in electric power system consumers of direct voltage 27 V receive electric energy from adjustable transformer of alternating voltage to direct voltage, input of which is connected through decreasing multi-phase transformer to output of magnetic-electric multi-phase high voltage alternating current generator connected to aircraft engine. On signal, marking transfer of aircraft engine to automatic-rotation mode, windings of decreasing transformer are linked by closing contacts, to provide transfer of electric energy to load through transformer 4 directly from output of alternating current generator. Electric power circuit continuously provides energy to consumers both in stationary mode and in mode of engine automatic-rotation operation. ^ EFFECT: improved energy conservation efficiency due to providing for continuous energy influx to consumers and better use of aircraft engine power with simultaneous improvement of mass-dimensional characteristics. ^ 2 cl, 1 dwg |
