A material having a plurality of impurity collection spaces has an outer face facing into a cooling air flow stream for a gas turbine engine component. Impurities such as sand or dirt will collect in the plurality of spaces. In a disclosed embodiment, a honeycombed material is utilized. The material may have a surface that will sit with at least a component parallel to an axial centerline of a gas turbine engine that is to receive the collection material. The material surface may also have a component which is generally perpendicular to the axial centerline. The material may be placed in a gas turbine engine upstream of the turbine section, and downstream of the combustion section. Moreover, the collection material may be placed such that there is cleaner air flow radially inwardly of the collection material, and heavier dirt-laden air passing along the collection material such that impurities can be collected.

The gas turbine engine as set forth in claim 1, wherein said collection material lies along a plane, said plane having at least a component which is parallel to an axial center line of the gas turbine engine. 8. The gas turbine engine as set forth in claim 7, wherein said plane also has a component which is generally perpendicular to said axial center line. 9. The gas turbine engine as set forth in claim 1, wherein said cooling air stream passes through a metering hole, and said collection material placed upstream and adjacent to said metering hole. 10. The gas turbine engine as set forth in claim 9, wherein said collection material is at least partially within an extended cross-sectional area of the metering hole. 11. A dirt collection material for being placed in a cooling air flow of a gas turbine engine comprising: a first collection material including a first outer face, the first collection material is mounted in a gas turbine engine such that the outer face is in contact with the cooling air flow; a second collection material having a second outer face that is parallel to an axial center line of the gas turbine engine; said both faces having a plurality of impurity collection spaces; and said first and second collection material are mounted on a particle collector member, and the particle collection member having a portion extending along a plane that will be transverse to said axial center line of the gas turbine engine. 12. The collection material as set forth in claim 11, wherein said face of said first and second collection material has a honeycomb shape. 13. The collection material as set forth in claim 11, wherein a flow guide will guide heavier dirt-laden air toward said first and second collection material. 14. The collection material as set forth in claim 11, wherein the cooling air flow passes through a metering hole, and said first and second collection material to be placed upstream and adjacent to the metering hole. 15. The collection material as set forth in claim 14, wherein said collection material is at least partially within an extended cross-sectional area of the metering hole. 16.
