Gas turbine including belly band seal anti-rotation device
Abstract:
A sealing band located in opposing seal band receiving slots of adjacent turbine disks to seal an annular gap therebetween. An anti-rotation body including a base portion is located between edges of the sealing band within the annular gap, and a pin portion extends axially from the base portion for engagement with a cut-out portion of at least one of the disks. A pair of spaced projections extend from the base portion and into through openings in the sealing band at a location within the annular gap. The projections define an attachment structure attaching the anti-rotation body to the sealing band.
