Abstract

Official abstract text for this publication.

A seal assembly between a hot gas path and a disc cavity in a turbine engine includes a non-rotatable vane assembly including a row of vanes and an inner shroud, a rotatable blade assembly adjacent to the vane assembly and including a row of blades and a turbine disc that forms a part of a turbine rotor, and an annular wing member located radially between the hot gas path and the disc cavity. The wing member extends generally axially from the blade assembly toward the vane assembly and includes a plurality of circumferentially spaced apart flow passages extending therethrough from a radially inner surface thereof to a radially outer surface thereof. The flow passages effect a pumping of cooling fluid from the disc cavity toward the hot gas path during operation of the engine.

First claim

Opening claim text (preview).

What is claimed is: 1. A seal assembly between a hot gas path and a disc cavity in a turbine engine comprising: a non-rotatable vane assembly including a row of vanes and an inner shroud; a rotatable blade assembly axially adjacent to the vane assembly and including a row of blades and a turbine disc that forms a part of a turbine rotor, the blades extending from a platform of the blade assembly; and an annular wing member located radially between the hot gas path and the disc…
