AIRCRAFT POWER PLANT Russian patent published in 2012 - IPC B64D33/00 F01K23/10 B60K6/32 H01M8/10 

FIELD: transport.

SUBSTANCE: hybrid power plant comprises high-temperature solid-oxide fuel cells with the outlet of their cathode chambers communicated via tight ducts with heat exchanger gas chambers, afterburner and micro turbine. The latter has output shaft coupled with radial-flow compressor. Inlet of said cathode chambers is communicated with air chambers of heat exchanger and compressor. Power plant comprises jet nozzle communicated with micro turbine outlet and propeller coupled with synchronous motor. The latter comprises superconducting elements cooled in rotor by liquid nitrogen. Said motor is connected via inverter to fuel cells. Tank with liquid nitrogen, motor rotor, inverter and evaporator communicated with fuel cell anode chamber inlet are concatenated via tight channels. Outlets of fuel elements are communicated with afterburner.

EFFECT: decreased specific weight, higher efficiency.
