(FR) RAINURE EN QUEUE D'ARONDE DESTINÉE À ÊTRE UTILISÉE AVEC DES ENSEMBLES ROTOR
Abstract
(EN) A turbine wheel is disclosed. The turbine wheel includes a plurality of first dovetail slots (300) and a plurality of second dovetail slots (100). The plurality of first dovetail slots and the plurality of second dovetail slots are alternately spaced circumferentially on a radially outer periphery of the turbine wheel (200). And a rotor assembly (600) is disclosed. The rotor assembly is used with the turbine wheel a plurality of first turbine buckets (700) and a plurality of second turbine buckets (800).
(FR) L'invention concerne une roue de turbine. La roue de turbine comprend une pluralité de premières rainures en queue d'aronde (300) et une pluralité de secondes rainures en queue d'aronde (100). La pluralité de premières rainures en queue d'aronde et la pluralité de secondes rainures en queue d'aronde sont espacées en alternance de manière circonférentielle sur une périphérie radialement externe de la roue de turbine (200). Un ensemble rotor (600) est également décrit. L'ensemble rotor est utilisé avec la roue de turbine, avec une pluralité de premières aubes (700) de turbine et avec une pluralité de secondes aubes (800) de turbine.
