GAS TURBINE ENGINE Russian patent published in 2009 - IPC F01D1/34 

FIELD: motors and pumps.

SUBSTANCE: gas turbine engine contains casing, gas turbine, located inside casing, system of feed, lubrication and regulation. Gas turbine is implemented in the form of hub, fixed on shaft, on which it is put on ring made of heat-insulating material. On ring it is fixed rim, corresponding connected to each other ladle of rectangular cross-section, allowing in middle part diffusion cell and opening to the side opposite to rotation of gas turbine. Longitudinal axis of each ladle with diametre line constitutes angle 110 degrees. From both butt sides of rim there are fixed heaters with windings, the second end of the first is connected to the first end of the second winding of heater. Two collector rings, one of which is connected to free end of the first winding of heater, and the second - with free end of the second winding of heater, are fixed on insulating bush, installed on trailing end of shaft and contact to carbon-baked brush. In the same place it is located drive gear of piston pump of actuating medium feeding, hydraulically connected by means of pipelines allowing heat insulation, with bin, implemented in the form of Dewar vessel and sprayers, located on casing. On casing it is also installed exhaust branch, connecting inner cavity of casing of gas turbine engine to atmosphere, actuating medium of which is liquid air. Trailing end of shaft is by means of coupling box connected to motor shaft, it is also current generator, electrically connected through control assembly to rechargeable battery and carbon-baked brush of collector rings.

EFFECT: invention is directed to increasing of operating characteristics of gas turbine engine.
