Abstract
L'invention concerne un disque porte-aubage pour rotor de turbine ou de compresseur de moteur à turbine à gaz comportant une partie radialement interne épaisse 24 et une partie radialement externe plus mince 20, la surface de cette dernière étant recouverte d'un enduit isolant thermique 28 fait d'un agent isolant en suspension dans une matrice céramique, ayant pour but d'atténuer les différences de dilatation thermique entre la partie mince et la partie épaisse pendant le fonctionnement du moteur.The invention relates to a blading disk for a turbine or compressor rotor of a gas turbine engine comprising a thick radially inner part 24 and a thinner radially outer part 20, the surface of the latter being covered with an insulating coating. thermal 28 made of an insulating agent suspended in a ceramic matrix, with the aim of attenuating the differences in thermal expansion between the thin part and the thick part during the operation of the engine.
