Abstract

Official abstract text for this publication.

A separator device is provided for separating dirt particles from a flow of cooling air fed to airfoils of the turbine section of a gas turbine engine. In use the separator device extends across a conduit which bypasses the combustor of the engine to convey pressurized cooling air carrying dirt particles from the compressor section of the engine to openings which direct the air into the airfoils. The separator device is configured to direct a first portion of the impinging cooling air flow away from the openings and to allow a second portion of the impinging cooling air to continue to the openings. The first portion of cooling air has a higher concentration of the coarsest dirt particles carried by the cooling air than the second portion of cooling air.

First claim

Opening claim text (preview).

The invention claimed is: 1. A separator device that separates dirt particles from a flow of cooling air fed to airfoils of the turbine section of a gas turbine engine comprising: an array of scoops that direct a first portion of impinging cooling air flow away from openings which direct the air into the airfoils and to allow a second portion of the impinging cooling air to continue to the openings; and an impingement surface provided on the array of scoops, wherein the separato…
