Abstract: A turbine engine component can include a surface comprising at least one edge and a coating disposed upon the surface that can extend to the edge. A spall break can be disposed along a line upon the surface adjacent the edge to prevent spallation of the coating from spreading from the edge onto the surface beyond the spall break. The spall break can comprise a discontinuity of the coating. A method of coating a turbine component can include preparing a substrate to receive a coating and selecting a fail location along the substrate for a coating. One or more coating can be applied to the substrate and a spall break can be incorporated into the one or more coatings. The spall break can comprise a line of discontinuity in the one or more coatings along the fail location.

Abstract: A joint weld between a rod and a hollow tube is disclosed. The rod has a cylindrical first end, and the hollow tube has a second end situated coaxially about a first axial length of the cylindrical first end. A plurality of circumferentially distributed scallops in the second end extend axially to at most a second axial length less than the first axial length to form an end pattern with varying axial extent as a function of circumferential position. The joint includes a weld along a perimeter of the end pattern, between the hollow tube and the rod.

Abstract: A gas turbine engine system comprises a rotor wheel, a plurality of blades, a lockwire and a locking key. The rotor wheel comprises a plurality of axial grooves extending through a periphery of the rotor wheel, and a plurality of posts formed between adjacent slots, each post having a circumferential slot. The blades are mounted in the axial grooves of the rotor wheel, each blade having a circumferential slot circumferentially aligned with the circumferential slots of the posts. The lockwire extends across the plurality of axial grooves of the rotor wheel within each of the circumferential slots of the posts and the blades from a first end to a second end to inhibit axial displacement of the blades within the grooves. The locking key is disposed between the first and second ends of the lockwire and provides support to at least one of the ends of the lockwire to prevent radially inward displacement.

Abstract: The subject matter of the present disclosure can help provide solutions to problems associated with eccentricities between mounting components in rotating gas turbine engine components, such as by providing a simulator component for balancing with an actual component outside of a gas turbine engine installation. The simulator component can allow for balancing of the actual component cumulatively with the simulator component for later installation of the actual component into a gas turbine engine with a simulated component simulated by the simulator component. The simulator component can have rotational dynamic properties, e.g., the same center of gravity and a scaled diametral moment of inertia, relative to the simulated component.
