Abstract
An assembly includes: a movable blade for a turbomachine including a tip; and a removable part including an anti-wear material, configured to be attached removably to an edge of the tip to limit wear of the tip.
Claims9
An assembly comprising:
- a movable blade for a turbomachine comprising a tip and an airfoil;
- and
- a removable part comprising an anti-wear material, the removable part being removably attached to the tip to limit wear of the tip,
- wherein the tip comprises a platform having a first edge on a pressure side of the movable blade and a second edge on a suction side of the movable blade, the removable part being attached to the first edge and to the second edge,
- wherein one of the first edge and the second edge presents a receding shape presenting a negative V shape and the other of the first edge and the second edge presents a protruding shape presenting a positive V shape to be received in a receding shape of an adjacent blade, a thickness of the platform diminishing toward an apex of the positive V shape and toward an apex of the negative V shape,
- wherein the removable part has two folded ends that are hook-shaped to sandwich a portion of the platform at the first edge and at the second edge, the anti-wear material being provided at the two folded ends, and
- wherein the removable part is in contact with the platform.
