Patent

CA 2565266

A non-positive-displacement machine bucket (1) is provided with a heat- insulating layer (41) on the outer contour of the blade (4). Only partial areas of the blade are specifically provided with the heat-insulating layer whereas well-defined second partial areas of the blade (42, 43, 44) are specifically provided without a heat-insulating layer. In particular, an area (42) along the rear edge (46) of the blade is provided without a heat- insulating layer. In other embodiments of the invention, areas of the blade (43, 44), which are adjacent to platforms of the blades situated on the side of the base (21) or the top (31), are provided without a heat-insulating layer.

L'invention concerne une aube de turbomachine (1), munie, sur le contour extérieur de la pale d'aube (4), d'une couche calorifuge (41). A cet effet, seules des zones partielles de la pale d'aube sont munies de manière très ciblée de la couche calorifuge, alors qu'une seconde catégorie de zones partielles de la pale d'aube (42, 43, 44) bien définies ne comportent pas de couche calorifuge. Il est notamment prévu une zone (42) sans couche calorifuge le long de l'arête arrière (46) de la pale d'aube. Dans d'autres modes de réalisation de l'invention, des zones de la pale d'aube (43, 44), situées au voisinage de plates-formes côté pied (21) ou côté tête (31) des aubes, ne comportent pas de couche calorifuge.
