    摘要： A gas turbine engine (10) includes a non-rotatable casing (112) that includes a honeycomb seal (102) that reduces wear to rotor seal teeth (110) disposed within the gas turbine engine. The gas turbine engine also includes a rotatable annular member (106) including a sealing assembly disposed between rotor and stator components. The rotatable annular member includes seal teeth that extend radially outward from the rotatable annular member. The stator components include a non-rotatable member that includes a honeycomb seal that extends radially inward. The honeycomb seal is fabricated from a material (130) that has a melting temperature less than approximately 2000° F.

    摘要： Multiple tubes (50, 52) are connected to steam supply and spent cooling steam return manifolds (42, 40) for supplying cooling steam to buckets and returning spent cooling steam from the buckets to the manifolds, respectively. The tubes are prevented from axial movement in one direction by flanges (62, 76) engaging end faces of the spacer (20) between the first and second-stage wheels (12, 14). Retention sleeves (86, 94) are disposed about cantilevered ends of the tubes. One end of the retention sleeve engages an enlarged flange on the tube, while an opposite end (90, 96) is spaced axially from an end face (89, 97) of the adjoining wheel, forming a gap ( a , b ), enabling thermal expansion of the tubes and limiting axial displacement of the tube in the opposite direction.

    摘要： A turbine frame 32 includes first and second coaxially disposed rings 36, 38 having a plurality of circumferentially spaced apart struts 40 extending therebetween. A plurality of clevises 52 join respective first ends 40a of the struts 40 to the first ring 36 for removably joining the struts 40 thereto. Each of the clevises 52 includes a base 54 removably fixedly joined to the first ring 36, and a pair of legs 62, 64 extending away from the base 54 and spaced apart to define a U-shaped clevis slot 66 receiving the strut first end 40a. The strut first end 40a is removably fixedly joined to the clevis legs 62, 64 by a pair of expansion bolts 70. The clevis base 54 includes a central aperture 60 aligned with a first port 48 in the first ring 36 for providing access therethrough. And, the strut first end 40a abuts the first ring 36 for carrying compressive loads therebetween and providing a seal therewith.
