GAS-TURBINE ENGINE Russian patent published in 2008 - IPC F02C3/55 

FIELD: mechanical engineering; gas-turbine engines.

SUBSTANCE: proposed gas-turbine engine has gas generator, high-pressure gas turbine whose input is pneumatically connected with output of gas generator through cylinder-gas receiver, and output communicates with atmosphere, and compressor. Gas-turbine engine contains also low-pressure turbine whose input is connected with output of high-pressure turbine, and output communicates with atmosphere. Shaft of turbine is connected with gas generator through overrunning clutch. Rotor secured inside cylindrical housing of gas generator is essentially hub provided with four radial blades made integral with hub and spaced through 90° relative to each other. Outlet and inlet branch pipes are made, accordingly, in upper and lower parts of cylindrical housing, outlet branch pipe being connected through cylinder-gas receiver with input of high-pressure turbine. Through channel is made in right-hand part of round cylindrical housing perpendicular to line passing through centers of outlet and inlet branch pipes. Spark plug is installed in said though channel which is essentially spiral wound on insulating base and heated by electric current. Holes are made coaxially to each other in left-hand part of round cylindrical housing opposite to spark plug on front and rear covers. Said holes are connected with branch pipes, one of which is connected through air cleaner with atmosphere, and the other is connected by pipeline with ejector nozzle installed inside intake pipeline of high-pressure turbine. Inlet branch pipe of gas generator is connected with fuel feed system and, through compressed air cylinder-receiver, with outlet channel of rotary bladed compressor. Inlet channel of rotary bladed compressor communicates with atmosphere through air cleaner.

EFFECT: increased capacity of gas generator.
