GAS-TURBINE ENGINE Russian patent published in 2005 - IPC

FIELD: mechanical engineering; gas-gas-turbine engines.

SUBSTANCE: proposed gas-turbine engine contains combustion chamber, compressor with high-pressure chamber, turbine, exhaust manifold and clutch for connection with consumer. Engine is furnished also with air reservoir made of refractory material ands installed inside working combustion chamber. Air reservoir is provided at one end with hole in form of elongated neck which is installed in center of neck of working combustion chamber. Both necks are installed at one level. At other end, air reservoir is provided with hemisphere with cone-shaped refractory material head installed from outer side. Hollow flat blades are installed at side of air reservoir by means of which air reservoir is attached to working combustion chamber. Nozzles of fuel conversion device with gas pass channels are installed on elongated neck of ignition device of combustion chamber from outer side. Air-cooling casing is installed around ignition device of combustion chamber over outer surface of engine. Axial-flow air compressor with low-pressure fan is installed on rear part of engine. Current generator-starter is fitted on one shaft with axial-flow air compressor. Current generator-starter is connected through automatic clutch with gas-air turbine to which buffer device with guide cone is rigidly connected. One of bearings of gas-air turbine shaft is rigidly secured to housing of buffer device. Energy conversion device is installed in intake part of mixing chamber by its third cylinder with maximum diameter of hole. Guide cone of buffer device of gas-air turbine is installed into mixing chamber from other side. Low-pressure air duct and high-pressure air duct are installed over outer surface of engine over entire length of mixing chamber and energy conversion device from axial-flow air compressor and fan.

EFFECT: improved reliability and increased service life of engine.
