Abstract: A sealing device including a sealing ring extending around the periphery of a gas turbine stator section and located between the stator section and the free ends of the stator vanes. The sealing ring is formed of individual segments movable radially relative to each other. Each two adjacent sealing ring segments have opposed faces, one face presenting projections and the other having correspondingly shaped recesses for accommodating the projections with clearance. Each opposed face has a groove at least as deep as the projection or recess in that face, and a flat plate is located in the opposed grooves. Springs or gas pressure press the sealing ring segments radially outwardly against the free ends of the vanes. The radius of curvature of the ring segments outer surfaces is smaller than that of the vane ends so that the segments and vane ends contact each other over only a portion of their surfaces.

Abstract: A wire ring bearing for an actuating guide apparatus for a gas turbine comprising two bearing rings concentrically arranged for relative motion with respect to one another between which is a plurality of rolling elements which are rollably supported on wire rings mounted in pairs respectively provided in circumferentially extending slots in the two bearing rings. One of the bearing rings comprises a plurality of individual ring elements which jointly define the slot in the corresponding bearing ring. A fastener secures the ring elements together with a spring interposed between the fastener and one of the individual ring elements. The fastener is engaged in a sleeve having a flange bearing against the head of the fastener and the spring has one end bearing against the flange and an opposite end bearing against the associated individual ring element.

Abstract: A bearing for the ceramic rotor of a turbine engine or turbomachine, which consists of an air-supported bearing providing for a lubricating air film between the inner and outer bearing rings at least at the higher operating speeds of the engine. This facilitates operation of the turbine engine or machine under high temperature and rotational speed operating conditions.
