摘要： A blade for turbo machine, in particular for a turbine, includes an airfoil body extending in a radial direction and comprising a suction side surface and a pressure side surface opposite to the suction side surface with regard to a circumferential direction that extends transverse to the radial direction, and a snubber structure. The snubber structure includes a first snubber element protruding, along the circumferential direction, from the suction side surface of the airfoil body, and a second snubber element protruding, along the circumferential direction, from the pressure side surface of the airfoil body wherein the first snubber element is connected to the suction side surface of the airfoil body by a concave curved first transition portion having a first radius, and wherein the second snubber element is connected to the pressure side surface of the airfoil body by a concave curved second transition portion having a second radius. The first radius is smaller than the second radius to reduce aerodynamic losses.

摘要： A flow body (100) for a gas turbine (300) includes an airfoil (1) extending along a radial direction between a platform end (11) and a tip (12) which has a tip surface (12a). The airfoil (1) is formed of a first metal material and comprises an inner cavity (10) for receiving a gaseous cooling fluid. The flow body (100) further includes a squealer tip (2) protruding from the tip surface (12a) of the tip (12) and extending along a circumference of the tip (12) so that the squealer tip (2) at least partially surrounds the tip surface (12a). The squealer tip (2) is formed from a second metal material and includes a plurality of internal cooling cavities (20) that are separated from each other within the squealer tip (2), wherein each of the internal cooling cavities (20) is in fluid communication with the inner cavity (10) via one or more fluid passages (15). A method for manufacturing a flow body (100) for a gas turbine (300) and a method for repairing a flow body (100) for a gas turbine (300) are also disclosed.
