FIELD: machine building.
SUBSTANCE: gas-turbine engine rotor contains impeller disks connected by surfaces of the internal and external ring seating elements, and bushings with the installed pins. In the internal and external ring seating elements cylindrical holes are made. The bushings are installed in holes of the external ring seating element, and have expanded area at the side of its internal surface. In bushings a holed for pin is made, its diameter is equal to the diameter of the cylindrical hole in the internal rings seating element. The pin is locked against movement in the radial direction using deformation of the bushing external surface.
EFFECT: invention increases reliability of connection of the rotor sections of the compressor or turbine, reduces overall dimensions of the connection of the ring seating elements.
