More Information
Summary:A sealing band arrangement for a gas turbine including first and second adjoining rotor disks separated by a gap wherein the first rotor disk includes an aperture. The sealing band arrangement includes at least one seal strip segment located within the gap, wherein the seal strip segment includes a raised portion having a first mating surface. The sealing arrangement further includes a locking pin having a planar section for receiving the first raised surface. The locking pin also includes a pin section having a second mating surface that abuts against the first mating surface to thereby lock the locking pin and the seal strip segment together. Further, the pin section is located within the aperture to stop circumferential movement of the seal strip segment relative to first and second disks.
