GAS-TURBINE ENGINE Russian patent published in 2006 - IPC F02C3/04 

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed internal combustion gas-turbine contains twin cylindrical body, combustion chamber, front and rear gas turbines, centrifugal compressor and power takeoff shaft. Ring space between engine body and coaxially arranged cylinder of combustion chamber is divided into two conical spaces narrowing towards power shaft. Longitudinal channels in walls of cone communicate with space of water-ring chamber and with spaces of longitudinal channels in walls of cylinder of combustion chamber, and through holes in its walls, with space of combustion chamber. Conical space adjoining combustion chamber communicates with atmosphere and with radially arranged hollow blades of straightening grid in space of combustion chamber opened to side of front centrifugal gas turbine. Air longitudinal channels on inner side of engine body are closed, and gas channels are opened to side of outer conical space accommodates long feathers of two-feather blades of front gas turbine converging to front end of engine and connected with rounding off with short wide feathers partially getting into space of combustion chamber. Outer and inner feathers of blades are turned to different sides relative to longitudinal axis. Outer side of rounded off part of blades is provided with smooth bends to side opposite to direction of rotation. Bends are interconnected to form bowl secured on cone of hollow power takeoff shaft, on outer side of which blades of centrifugal compressor are secured. Centrifugal compressor communicates with atmosphere through axial blower in center of rear axial-flow turbine and, though guide grid in rear cover, with air longitudinal channels on inner side of engine body which communicate with space of front part of combustion chamber through radial outlets and beveled bottoms on their ends. Gas channels are arranged between air channels. Ends of their sides from side of compressor are interconnected and bent to side opposite to direction of rotation.

EFFECT: improved economy of gas-turbine engine.
