    摘要： In a blading member for a fluid flow machine, the blading member comprising a platform member (2) and at least one airfoil member (1), the platform member comprising a platform member receiver section (6), said platform member receiver section comprising a first face (7) and a second face (8), and a platform member receiver opening (5) being disposed in the receiver section, the receiver opening extending from the first face, the airfoil member extending from an airfoil base (16) to an airfoil tip and comprising an airfoil member foot section (4) and an airfoil member aerodynamic section (3), wherein the airfoil member foot section extends from the airfoil base to the airfoil member aerodynamic section and the airfoil member aerodynamic section extends from the airfoil member foot section to the airfoil tip, the airfoil member foot section comprising an airfoil member male mating section (14) received within the platform member receiver opening (5) and the airfoil member aerodynamic section projecting from the first face (7) of the platform member receiver section, at least one support shoulder (12) is disposed on the airfoil foot section (4) and a counterpart support shoulder (13) is disposed on the platform member, wherein the support shoulder and the counterpart support shoulder abut each other, one support shoulder and a corresponding counterpart support shoulder are beveled, wherein the bevel angles (a) of said support shoulder and said corresponding counterpart support shoulder are identical at least at corresponding mating points.
