ELECTRICAL POWER SUPPLY CIRCUIT IN AIRCRAFT FOR ELECTRICAL EQUIPMENT INCLUDING A DE-ICING CIRCUIT

PROBLEM TO BE SOLVED: To provide a power circuit capable of supplying electric power to an aircraft engine and/or a plurality of electric facilities in its circumference. SOLUTION: The power circuit of the aircraft is furnished with an electric power distribution network 17 on a frame of the aircraft to feed electric power to the aircraft engine or the electric facility 5b positioned in the circumference of the aircraft engine and an electric power generator 27 integrated with the aircraft engine to feed electric power to a deicing circuit 5a. The electric facility is furnished with a load 5b of a nacelle connected to a direct current voltage electric power distribution bus 35, and the bus 35 itself is connected to a voltage converter circuit 34 to be fed with electric power by the electric power distribution network 17. The deicing circuit 5a is furnished with at least one electric resistance 61 to dissipate electricity to be returned to the direct current voltage electric power distribution bus 35 probably by at least a part of the load of the nacelle.
