Patent

CA 2698483

A gas turbine rotor blade (2) and rotor disk (4) arrangement employs a coating (74) in order to seal the gap which normally exists between the bottom part of the blade root and the bottom part of the disk slot. The coating (74) may be applied to the blade root or to the disk itself on the bottom part of the disk slot. The coating is preferably an abradable nickel-alloy Bentonite coating. The coating may also be applied to only a portion (70, 72) of the areas being sealed, omitting a portion at the Start of the slot or at the Start of one of the lobes of the blade root, so that a lead-in is formed, whereby the blade can more easily be inserted into the slot.

Un ensemble pale et disque de rotor de turbine à gaz comporte un revêtement qui sert à combler l'espace qui existe normalement entre la partie inférieure du pied de pale et la partie inférieure de la fente de disque. Le revêtement peut être appliqué sur le pied de pale ou sur le disque lui-même, sur la partie inférieure de la fente de disque. Le revêtement est de préférence un revêtement abradable à base d'un alliage de nickel et de bentonite. Le revêtement peut en outre être appliqué uniquement sur une partie des zones devant être protégées, à l'exception d'une partie située au départ de la fente ou au départ d'un des lobes du pied de pale, de manière à former un passage, la pale pouvant ainsi être insérée plus facilement dans la fente.
