Abstract: An abradable member, such as gas turbine engine seal for rotary components, is restrained against axial movement relative to an adjacent component via a lip retention engagement.

Abstract: A sleeve mounting arrangement for use with a rotary component comprises a housing having a sleeve reception aperture defined along a rotation axis of the rotary component. The sleeve is positioned and retained within the housing by means of an adhesive provided in a pocket defined between the sleeve and the housing.

Abstract: A repairable labyrinth seal of a gas turbine engine comprises at least one fin having a base with a thickness and a tip portion extending therefrom. A shoulder distinguishes the base from the tip portion. The shoulder defines a machining site suitable for receiving a welded replacement piece for shaping a new tapered tip portion following removal of a worn tapered tip portion.

Abstract: A gas turbine engine has a compressor assembly and a turbine assembly rotationally mounted on a shaft, the turbine assembly being driven by hot gases discharged from a combustion chamber disposed between the compressor and turbine assemblies, the compressor having a centrifugal impeller for pressurizing and impelling air into the combustion chamber. The engine also includes an impeller shroud covering the bladed portion of the centrifugal impeller, the impeller shroud having a support bracket having a thin and curved load-isolating profile for supporting a strut that secures the impeller shroud to a case of the engine.
