Abstract
An assembly for a gas turbine engine includes a seal and a flow diverter. The flow diverter is disposed adjacent the seal to direct a secondary gas flow that passes across the seal away from a rotor cavity such that the secondary gas flow travels back toward a main gas flow path of the gas turbine engine.
Claims13
An assembly for a gas turbine engine, comprising:
- a seal;
- a flow diverter disposed adjacent the seal to direct a secondary gas flow that passes across the seal away from a rotor cavity such that the secondary gas flow travels back toward a main gas flow path of the gas turbine engine, wherein the flow diverter is positioned adjacent the seal to act as a backup seal in instances where the seal fails;
- and
- a labyrinth seal disposed adjacent the flow diverter, wherein the flow diverter and a land of the labyrinth seal are spaced radially to form an annular gap therebetween that defines a flow path at least partially bounded by radially-opposed surfaces of the land and the flow diverter along which the secondary gas flow travels.

An assembly for a gas turbine engine, comprising:
- a first component;
- a second component, wherein the first component and the second component are disposed radially inward of a main gas flow path of the gas turbine engine;
- a finger seal mounted to and extending from the first component to contact the second component;
- and
- a flow diverter disposed adjacent the finger seal and mounted to the first component, wherein the flow diverter and the second component are radially spaced such that radially-opposed surfaces of the flow diverter and the second component form an annular gap to direct a secondary gas flow that passes across the finger seal through the annular gap and along the second component;
- wherein the second component comprises a labyrinth seal, and wherein the secondary gas flow passes between a land and one or more knife edges of the labyrinth seal.
