Abstract

1,236,366. Turbines. WESTINGHOUSE ELECTRIC CORP. May 7, 1969 [May 22, 1968; July 17, 1968], No. 23268/69. Heading F1T. Leakage through the gaps between adjacent inner shroud segments 26 of a gas turbine stator blade ring is prevented by axially and radially extending metal sealing strips 42, 44 fitting in intersecting grooves 46, 48 respectively. Each strip 42 has a notch 50 receiving a tab 52 on the strip 44, the latter being retained in position by a pin 56 passing through holes in the strip 44 and in flange 40. The pin 56 is welded to the flange. Strip 42 is parallelogram shaped to allow for the slight inclination to the axial direction of the end faces of the shroud segment 26. Similar sealing strips may be provided at the adjacent faces of outer shroud segments 24.
