INTERNAL COMBUSTION AIR-INJECTION-ROTOR-TURBINE ENGINE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; gas-turbine engines. SUBSTANCE: internal combustion air-injection-rotor- turbine engine has combustion chamber, centrifugal compressor with blades arranged on front part of disk. Turbine is mounted on the same shaft as compressor. Blades are arranged inside ring rotor. Shape of combustion chamber with guide hole of cover ring and hole of disk working ring is close in shape to reaction nozzle whose axis passes tangentially to ring rotor. Hollow frame turbine is provided at back side of disk. Rear part of turbine changes into cylindrical exhaust nozzle. Outer surface of turbine has gas channels formed by screw ribs starting at hole of disk working ring and downcasting to perforated part of cylindrical exhaust nozzles accommodating auger labyrinth with variable pitch.
