摘要： A method of manufacturing an erosion-shielded turbine blade includes providing a turbine blade for use with a rotary machine. The turbine blade includes an airfoil extending between a root and a tip. The airfoil includes a pressure side and an opposite suction side, and each of the pressure and suction sides extends between a leading edge and a trailing edge. The method also includes printing a green body part by an additive manufacturing process by selectively depositing a binder solution across a particulate erosion-resistant material, and sintering the green body part to produce a post-sintering erosion shield that includes densified erosion-resistant material. The method also includes coupling the erosion shield to the leading edge of the turbine blade.

摘要： An inspection system for a cylindrical member includes at least one retention member positionable about at least a portion of a circumference of the cylindrical member. The inspection system also includes a positioning system and at least one housing. The at least one housing is coupleable to the at least one retention member at each of a series of circumferential inspection locations. The at least one housing includes at least one probe. The positioning system cooperates with the at least one retention member to position the at least one probe at each of the circumferential locations. The at least one probe is configured to send and receive a signal through an interior of the cylindrical member.

摘要： A method of forming an erosion shield for a turbine blade includes depositing a layer of filler material defining an upper surface. The method also includes depositing a layer of erosion-resistant material across the upper surface of the layer of filler material. An interface is defined between the layer of filler material and the layer of erosion-resistant material and has a shape of the upper surface. The method also includes machining the layer of filler material to produce the erosion shield. The erosion shield has the layer of erosion-resistant material, the machined layer of filler material, and the interface defined therebetween. An inner surface of the erosion shield is defined by the machined layer of filler material that is sized and shaped for attaching to a leading edge of the turbine blade. Each of the interface and the inner surface extend a length of the erosion shield.

摘要： A block assembly for locking a toothed gear housed in a frame includes a body shaped to couple to a portion of the frame adjacent to the gear for translation in a first direction parallel to an axis of the gear, and a locking block coupled to the body that includes at least one locking tooth shaped complementary to at least one gear tooth of the gear. The block assembly further includes an adjustment mechanism operable, when the body is coupled to the frame, to move the locking block in a second direction that is substantially orthogonal the axis of the gear, such that at least one locking tooth is received between a circumferentially spaced pair of the gear teeth to prevent movement of the toothed gear.
