AIRCRAFT POWER PLANT Russian patent published in 2018 - IPC F02K7/16 F02K3/77 

FIELD: aircraft engineering.

SUBSTANCE: aircraft power unit contains a turbo-compressor unit, a solid oxide fuel cell battery with outputs for the anode and cathode gases, a separately located traction fan, a fuel pump. Turbocharger unit includes a low pressure circuit and a high pressure circuit with a combustion chamber, fuel flow controller is made with two outlets, one of which is connected to the combustion chamber. Outputs for the anode and cathode gases of the solid oxide fuel cell stack are connected by gas lines to the inlet of the combustion chamber. Traction fan is equipped with an electric motor, electrically connected to the solid oxide fuel cell battery. Aircraft power plant is equipped with a reformer, associated with a battery of solid oxide fuel cells to form an electrochemical generator. High pressure circuit contains a damper and an additional circuit formed by an internal fan and an electrochemical generator. Combustion chamber is in the form of a low-emission combustion chamber with a flame stabilizer connected to an outlet gas duct of an anode gas of an electrochemical generator, Second output of the fuel flow controller is connected to the input of the reformer of the electrochemical generator.

EFFECT: invention ensures the improvement of the environmental performance of the aircraft power plant on the take-off mode and the increase in its economy on cruising conditions.
