Abstract: A retention and control system includes a rotor configured to rotate about an axis. A shroud ring has a peripheral groove and surrounds the rotor with a clearance defined between the rotor and the ring. A support ring engages the shroud ring in the peripheral groove and axially locates the shroud ring. The support ring includes a series of tabs, each with an aperture, projecting radially outward from the support ring. A retention spring engages the support ring radially outward from the shroud ring and includes a series of openings, one of which registers with each of the apertures. An alignment pin extends through each of the registered openings and apertures to locate the support ring and the engaged shroud ring concentrically with the turbine about the axis.

Abstract: A system for coupling a shroud to a case associated with a gas turbine engine and a gas turbine engine including such a system includes the case defining a bore and the shroud retained within the case. The shroud defines a pocket. The system includes a pin received through the bore and at least partially positioned within the pocket. The pin has a perimeter. The system includes a load spreader including a first side and a second side opposite the first side. The first side is interconnected to the second side by a flexible portion. The first side, the second side and the flexible portion are received about a portion of the perimeter of the pin, and the load spreader is configured to transmit at least one of an axial point load and a circumferential point load from the pin over a surface of the shroud.
