Abstract: A fixture assembly for use with air plasma spraying coating application processes includes a support member configured to be rotationally indexed, a first buttress, and a second buttress. The support member includes a first portion and a second portion fixedly supported by the first portion in a T-shaped configuration. The second portion has a first end and an opposite second end. The first buttress is secured to the second portion of the support member at or near the first end, with the first buttress configured to secure a first work piece. The second buttress is secured to the second portion of the support member at or near the second end, with the second buttress configured to secure a second work piece. The second buttress is arranged symmetrically with respect to the first buttress.

Abstract: A ceramic shroud assembly suitable for use in a gas turbine engine comprises a metal clamp ring shrink fitted around a ceramic shroud ring and an insulating and compliant interlayer. The interlayer is positioned between the metal clamp ring and the ceramic shroud ring.

Abstract: A self-aligning hanger for use in a gas turbine engine exhaust system comprises a first bracket, a second bracket, a rod, a first ball joint and a second ball joint. The first bracket is for connecting to an exhaust duct of the gas turbine exhaust system. The second bracket is for connecting to an exhaust duct liner of the gas turbine exhaust system. The rod extends between the first bracket and the second bracket. The first ball joint connects a first end of the rod with the first bracket. The second ball joint connects a second end of the rod with the second bracket.

Abstract: A doubler assembly repairs at least one damaged aperture of a composite flange. The doubler assembly includes an insert, an adhesive, and a support. The insert is positioned in the damaged aperture to provide compressive load transfer through the composite flange. The adhesive is positioned directly on at least a portion of the composite flange proximate the damaged aperture. The support is positioned over the adhesive.

Abstract: A torque tube assembly for transmitting rotational force from a first end to a second end includes a number n of concentric elongate torque tubes, where n is an odd integer greater than or equal to three. The concentric elongate torque tubes are connected for co-rotation. A serpentine thermal conduction path is defined between the first end of the torque tube assembly and the second end of the torque tube assembly, and includes at least a portion of each of the concentric elongate torque tubes.

Abstract: A unitary bimetallic shield ring for a superconducting generator rotor includes coaxial inner and outer cylindrical portions. The outer cylindrical portion comprises a first metallic material for conducting eddy currents to dissipate energy, and defines an interior face. The inner cylindrical portion comprises a second metallic material for providing structural support to the outer cylindrical portion. The inner cylindrical portion is continuously metallurgically joined with the interior face of the outer cylindrical portion. The shield is made by first forming a substantially continuous weld between the inner and outer layers, and then machining the shield.
