TURBOMACHINE BLADE

摘要

A blade, in particular a rotor blade, for a turbomachine, in particular a gas turbine, having an airfoil (10) for deflecting a working fluid that has a pressure side (11) and a suction side that are joined at a leading and a trailing edge (12, 13), and having a blade root (20); in the blade, a radial channel (6) being formed into which an impulse element (3) and a contact means (40.1-40.N; 41, 42) are introduced through a blade root-side insertion opening (23) that supports the impulse element with clearance of motion(s) in the axial and/or circumferential direction on the blade root side.

1. A blade comprising:
an airfoil for deflecting a working fluid, the airfoil having a pressure side and a suction side joined at a leading and a trailing edge; and a blade root; a radial channel being formed in the blade, an impulse element and a contact being introduced through an insertion opening in a blade root-side, the contact supporting the impulse element on the blade root side with clearance of motion in an axial or circumferential direction.
