摘要： An apparatus for inspecting a tip shroud includes a frame having top and bottom surfaces. A first stop is connected to the bottom surface to contact a first side surface of the tip shroud, and a second stop is in sliding engagement with the frame to contact a second side surface of the tip shroud. A method for inspecting a tip shroud includes placing an apparatus against the tip shroud, wherein the apparatus has a first stop connected to a frame and a second stop in sliding engagement with the frame. The method further includes engaging the first stop with a first side surface of the tip shroud and sliding the second stop with respect to the frame until the second stop contacts a second side surface of the tip shroud.

摘要： A rotating airfoil component of a turbomachine, in which the component has an airfoil aligned in a spanwise direction of the component, a shank, and a platform therebetween oriented transverse to the spanwise direction. The platform has an outer radial surface adjacent the airfoil, and at least one recessed region defined in its outer radial surface. The recessed region extends opposite the spanwise direction from a platform plane that contains portions of the outer radial surface that are upstream and downstream from the recessed region. The recessed region is contiguous with an end wall of the platform and extends therefrom toward the airfoil. The recessed region defines a surface shape whose boundary is contained by the platform plane, and has a profile shape that extends from the end wall toward the airfoil. The recessed region is sized and shaped to increase the stiffness of the platform.
