Abstract

L'invention concerne un rotor de turbine à gaz, comprenant un disque (20a, 20b) ayant une pluralité d'alvéoles (18) formées à sa périphérie extérieure, et une pluralité d'aubes (16) montées chacune par un pied (17) dans une alvéole du disque. Le disque comprend plus d'alvéoles que d'aubes, le rotor comprenant en outre au moins une masse d'équilibrage (28) logée dans une alvéole du disque non occupée par un pied d'aube.A gas turbine rotor, comprising a disk (20a, 20b) having a plurality of cells (18) formed at its outer periphery, and a plurality of vanes (16) each mounted by a root (17). ) in a socket of the disc. The disc comprises more cells than blades, the rotor further comprising at least one balancing mass (28) housed in a cell of the disc not occupied by a blade root.
