ROTOR OF AXIAL GAS TURBINE Russian patent published in 2018 - IPC F01D5/08 

FIELD: engine building.

SUBSTANCE: rotor of the axial gas turbine contains a disk with cooled blades and pins, a covering disk, forming channels for supplying cooling air to the tail end of the blades, both disks are provided with annular flanges for fastening the pins installed with a radial clearance relative to each other, and at the location of each pin there is a bracket, one end of which is placed in the gap, and the other end from the side of the pin cap. Pins are installed at an acute angle to the longitudinal axis of the disk, and in the annular flanges of both disks there are grooves placed between the pins and mating with each other.

EFFECT: technical result: reduction of voltage in the disks, occurring in the zone of axial holes in the disks during engine operation, and improved reliability of the axial turbine, simplified manufacture and assembly.
