HYDROGEN GAS-TURBINE ENGINE Russian patent published in 2015 - IPC F02K7/16 

FIELD: engines and pumps.

SUBSTANCE: solution of the specified tasks is achieved in a hydrogen gas-turbine engine containing an air intake, a housing, a compressor with a compressor rotor having a shaft, a combustion chamber installed after the compressor and connected to it via an air path, and a jet nozzle so that between the compressor and the combustion chamber inside the air path connecting the compressor to the combustion chamber there installed is a hydrogen birotary turbine that has external and internal rotors, inlet and outlet manifolds and the second shaft connected to the external rotor; the internal rotor is connected to the compressor rotor shaft, and a heat exchanger is installed after the combustion chamber and its inlet is connected to a fuel line and its outlet is connected to the inlet manifold of the turbine; the outlet manifold of the same turbine is connected via a pipeline to the main combustion chamber; the second compressor is installed at the heat exchanger outlet; with that, the hydrogen birotary turbine and the second compressor are connected by means of the second shaft. The jet nozzle can be of a supersonic type.

EFFECT: improving power performance of a gas-turbine engine; improving a compression degree of a compressor; increasing engine thrust force and improving its specific characteristics.
