BIROTATING BYPASS GAS TURBINE ENGINE Russian patent published in 2023 - IPC F02K3/65 F02C3/73 

FIELD: gas turbine engines.

SUBSTANCE: birotating bypass gas turbine engine containing a non-rotating combustion chamber, a jet nozzle, and a birotating turbine with a birotating compressor. The birotating compressor is made inside the birotating turbine, a fairing is installed concentrically with the outer rotor of the turbine, inside which one working stage of the fan is installed with a fan guide stage behind it, and the non-rotating combustion chamber is made cylindrical, at the junction of the birotating compressor with the birotating turbine with the possibility of turning the air flow from birotating compressor at 180°, and the outlet from the birotating turbine is connected by turning the flow of combustion products by 180° - with a central cylindrical channel inside the birotating compressor and with a jet nozzle at the outlet of the engine. All connections of the stators and rotors of the birotating compressor and birotating turbine to each other and to the combustion chamber are protected by connection protection units.

EFFECT: increased efficiency of the compressor and turbine and simplified design.
