Summary: | A retention and control system (60) includes a rotor configured to rotate about an axis. A shroud ring (88) has a peripheral groove (108) and surrounds the rotor with a clearance (92) defined between the rotor and the ring. A support ring (96) engages the shroud ring in the peripheral groove and axially locates the shroud ring. The support ring includes a series of tabs (111-115), each with an aperture, projecting radially outward from the support ring. A retention spring (98) 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 (102) 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. |
