Abstract
Official abstract text for this publication.
An apparatus for providing foreign object debris protection an air intake of an aircraft engine. The apparatus includes a frame and a plurality of cross-members. The cross-members are positioned in the frame to define a plurality of screen openings. At least one of the cross-members has an aerodynamically efficient cross section.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for providing foreign object debris protection for an air intake of an aircraft engine, the apparatus comprising; a frame; a plurality of cross-members positioned in the frame to define a plurality of screen openings, wherein the plurality of cross-members form a mesh assembly supported by the frame, the mesh assembly having a first tier and a second tier with a first portion of the plurality of cross-members being in the first tier and a second portion of the plurality of cross-members being in the second tier, the first tier and second tier together defining a mesh of the mesh assembly, the first tier overlapping and in thermal communication with the second tier; and wherein at least one of the cross-members has an aerodynamically efficient cross section. 2. The apparatus according to claim 1 , wherein the plurality of cross-members are tubular. 3. The apparatus according to claim 1 , wherein the frame is also configured to support a mesh that is not configured to be heated. 4. The apparatus according to claim 1 , wherein the first portion of the plurality of cross-members are are positioned generally parallel to each other. 5. The apparatus according to claim 4 , wherein the second portion of the plurality of cross-members are positioned generally parallel to each other and cross the first portion of the plurality of cross-members to form a mesh. 6. The apparatus according to claim 5 , wherein the mesh is configured to prevent foreign object debris from entering the air intake of the engine. 7. The apparatus according to claim 1 , wherein the first portion of the plurality of cross-members are tubular and the second portion of the plurality of cross-members are solid wire links. 8. The apparatus according to claim 1 , wherein the aerodynamically efficient cross-section is teardrop shaped. 9. The apparatus according to claim 8 , wherein a tail of the cross-section is narrow. 10. The apparatus according to claim 8 , wherein a tail of the cross-section pointed. 11. The apparatus according to claim 8 , wherein a tail of the cross-section is rounded. 12. The apparatus according to claim 1 , wherein the aerodynamically efficient cross-section is generally diamond shaped. 13. The apparatus according to claim 12 , wherein one end of the cross-section is general rounded. 14. The apparatus according to claim 13 , wherein both ends of the cross section are rounded.
