Patent number: 9410439Abstract: A blade root shim comprises a base, a suction side shim wall, a pressure side shim wall, and a contact relief region. The base extends longitudinally between a leading shim end and a trailing shim end. The suction side shim wall extends along the base and corresponds to a suction side blade root bearing surface. The pressure side shim wall, spaced circumferentially apart from the suction shim wall, corresponds to a pressure side blade bearing surface. The contact relief region is formed into an upper wall portion of either the suction side shim wall or the pressure side shim wall.Type: GrantFiled: September 14, 2012Date of Patent: August 9, 2016Assignee: United Technologies CorporationInventor: Blake J.

Patent number: 8834106Abstract: A seal assembly for a gas turbine engine includes a seal body and a biasing support member. The seal body includes a generally annular shape that defines an outer diameter surface. The biasing support member is circumferentially disposed about the outer diameter surface of the ceramic matrix composite seal body and includes an array of spring fingers that circumferentially overlap about the biasing support member. The array of spring fingers contacts the seal body and centers the seal body relative to the centerline axis of the gas turbine engine.Type: GrantFiled: June 1, 2011Date of Patent: September 16, 2014Assignee: United Technologies CorporationInventor: Blake J.
