BRUSH SEALS

摘要

A method of assembling a brush seal between two components (15, 16) having confronting adjacent surfaces (18, 24), such as the stator and rotor of a gas turbine, comprises providing a slot (19) in one of the components (16) which slot opens through the confronting surface of that component to face the other component (15). A flexible brush seal element (23) having a plurality of metallic bristles (25) is pushed into the slot (19) so that the free ends (29) of the bristles project from said surface of the one component. The element (23) is then held in position in the slot (19) by means of an anchoring strip (28) pushed into the slot so as to bear on a wall (20) thereof and also on the brush seal element (23), the anchoring strip tipycally being of a malleable metal.
