Abstract
A turbine flowpath assembly includes a plurality of circumferentially spaced apart airfoils disposed within an annular outer casing. Each of the airfoils includes outer and inner integral bands. A plurality of flowpath outer and inner panels are disposed between adjacent ones of the bands and circumferentially overlap the bands. The panels and bands are joined together at the respective overlaps using tripod plates and fasteners therethrough for allowing circumferential movement therebetween while providing sealing.
Claims8
A tripod plate for use in joining together by a bolt and a nut, a band and an overlapping panel in a gas turbine flowpath assembly comprising:
- an upper surface having a concave spherical seat therein;
- an oppositely facing inner surface having a pair of laterally spaced apart elevated buttons at a first end of said plate configured for contacting said panel to allow sliding movement thereon, and an elevated foot spaced from said buttons at a second, opposite end of said plate and configured for resting in an indentation in said band to lock said foot into position on said band and allow sliding movement of said panel relative to said band;
- and
- an access hole extending through said plate from said spherical seat to said inner surface between said buttons and said foot for receiving said bolt.
