Abstract: The present disclosure is directed to a coupling assembly for a turbomachine. The coupling assembly includes a liner and a sleeve at least partially positioned circumferentially around the liner. A frame is positioned between the liner and the sleeve. The frame includes a first side wall, a second side wall, and a base wall extending from the first side wall to the second side wall. A block is positioned between the liner and the sleeve and is movable relative to the frame to permit the block to move toward and away from the base wall. Moving the block away from the base wall causes the block to exert an inward force on the liner and the base wall to exert an outward force on the sleeve.

Abstract: A tool for repairing an out-of-round component such as a combustor body is disclosed. The tool includes a base including a first arcuate member; a second arcuate member; and a linear actuator coupling the second arcuate member to the base. The linear actuator moves the second arcuate member between a retracted position out of engagement with the out-of-round component and an extended position in which the first arcuate member and the second arcuate member engage an interior surface of the out-of-round component in an opposing relationship to force the out-of-round component into a more round state compared to an initial state of the out-of-round component. A related method is also disclosed.

Abstract: A connector interface may include an arrangement of contacts in a first connector, and a corresponding, complementary arrangement of contacts in a second connector mating with the contacts of the first connector. The contacts may be signal contacts or ground contacts. When the connectors are mated, a ground may be established between the connectors by the mating of the ground contacts from the respective connectors. The ground contacts in the first connector may be shaped to bridge together an array of ground contacts in the second connector when the connectors are mated. Such bridging tends to establish a continuous ground along the array of ground contacts, creating a more robust ground than in an otherwise identical connector.
