Abstract

Rotor de machine axiale, notamment de compresseur axial, à disque porteur, aubes amovibles et masselottes d'équilibrage. Le pourtour du disque comportant des rainures à parois en contre-dépouille dans lesquelles sont insérés les pieds prismatiques des aubes, les masselottes comportent aussi des pieds prismatiques en vue de leur insertion dans des espaces de rainures non occupés par les pieds d'aubes. Compresseurs pour turbo-réacteurs.
