Patent Images
1. A turbine engine sealing arrangement, comprising:
- a blade array rotatable about an axis, the blade array having a plurality of blades extending radially from the axis;
a control ring circumferentially disposed about the blade array; and
a plurality of tiles secured relative to the control ring, the plurality of tiles together establishing an axially extending seal with one of the plurality of blades as the one of the blades is rotated relative to the plurality of tiles from a circumferential end portion of the plurality of tiles to an opposing circumferential end portion of the plurality of tiles, wherein each of the plurality of tiles is separate and distinct from other tiles within the plurality of tiles, wherein the plurality of tiles comprises at least one inner tile and at least two outer tiles, the at least one inner tile configured to be secured relative to the control ring axially between opposing ones of the at least two outer tiles.
