COMPRESSED COMBUSTION GAS-TURBINE INTERNAL COMBUSTION ENGINE Russian patent published in 2020 - IPC F02C3/05 F02C3/16 F02C7/232 F02C7/18 

FIELD: machine building.

SUBSTANCE: invention relates to propulsion engineering, namely to gas turbine engines, and can be used on modern aircraft, sea vessels and tanks. Combustion-ignition internal-combustion gas-turbine engine comprises centrifugal compressor (1), gas centripetal turbine (2) and combustion chamber (3). Centrifugal compressor and gas centripetal turbine are made in one housing rotating about fixed axis. Blades of the centrifugal compressor and turbine are of complex configuration and make an integral part smoothly changing into each other. Width of section of blades of turbine part is twice more than width of section of blades of compressor part. Cavities between vanes and device housing at the point of centrifugal compressor blades transition into turbine ones form combustion chambers with increase of flow section along combustion gases flow direction. Fuel is fed into combustion chambers via channels (4) made in fixed axis and engine housing. Radial fuel channels are equipped with centrifugal valves (5) which open at minimum engine rpm to ensure ignition of fuel, and are closed when maximum permissible rpm is exceeded by strength criteria.

EFFECT: technical result consists in improvement of efficiency of gas turbine internal combustion engine with compression from compression due to implementation of centrifugal compressor and gas centripetal turbine in one housing rotating around fixed axis with common blades of complex configuration.
