FIELD: engines and pumps.SUBSTANCE: gas turbine engine rotor comprises working wheel discs connected by the surfaces of locating ring elements with cylindrical radial through bores made therein with retaining elements. Extended section is made on the part of every said bore on inner surfaces of locating ring elements, on the side of their outer surface. Retaining elements are composed of sleeves with internal thread arranged at extended sections and pints with appropriate outer thread locked at said bores by expansion. Working wheel discs are interconnected at their mid part along rotor lengthwise axis.EFFECT: higher reliability, manufacturability and reparability.2 cl, 2 dwg |
