More Information
Summary:A rotating blade for a gas turbine (5) is provided with: €¢ a root (17) configured to be coupled to a disc of the gas turbine (5) which rotates about an axis (A) of the gas turbine (5); a platform (20) coupled to the root (17); €¢ an airfoil (18) extending from the platform (20) and provided with a tip (23) radially opposite to the root (17) or the platform (20); the airfoil (18) comprising a leading edge (27), a trailing edge (28), a pressure side (25) and a suction side (26); €¢ at least one snubber (22; 22a, 22b) projecting from the suction side (26) and/or the pressure side (25); the snubber (22; 22a, 22b) being shaped so as to create a centripetal force towards the root (17) opposing the centrifugal force generated during the rotation of the disc to which the blade (15) is coupled.
