AIRCRAFT POWER SUPPLY SYSTEM Russian patent published in 2015 - IPC B64D41/00 

FIELD: electricity.

SUBSTANCE: system comprises accumulator batteries, control, adjustment and protection equipment, DC-AC converter, thermoelectric elements consisting of hot- and cold-junction heat exchangers, and a charge controller. The hot-junction heat exchangers are mounted at inner surfaces of combustion chambers, flame stabilisers, turbojet engine afterburner. The cold-junction heat exchangers are mounted at the aircraft outer skin. The charge controller is coupled to output of thermoelectric elements and to input of accumulator batteries as well to input of DC-AC converter. Outputs of DC-AC converter as well as DC-DC outputs are the device outputs. Output of the DC-AC converter is connected to input of the controlling, adjusting and protecting unit. Output of accumulator batteries is coupled to DC-DC input of the converter. Output of the DC-DC converter is coupled to the input of the controlling, adjusting and protecting unit. Output of the controlling, adjusting and protecting unit is coupled to input of the accumulator batteries.

EFFECT: providing power supply to consumers when generators are not available.
