Axial brush seal for a gas turbine engine

摘要

A brush seal joint 100 connects a first section 110 of a gas turbine engine casing and a second section 120 of the engine casing. The joint allows for movement between the casings. The joint comprises a plurality of flexible elongate members 130 extending from an edge 111 of the first casing 110 and an opposing edge 121 of the second casing 120. A first end 131 of the members adjacent the edge 111 of the first section 110 is moveable relative to the edge 111 of the first section of the casing 110 to seal the joint. The second end 132 of the members may be fixed relative to the second edge 121 of the second casing 120. The flexible elongate members may be bristles, plates or finger shaped members. A later embodiment relates to a component for constructing a barrier, characterised by a plurality of elongate flexible members with a sleeve member 140 which encases a plurality of the ends of the flexible members not attached to the barrier section.
