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; and wherein at least one of the cross-members has an aerodynamically efficient cross section. 2 . The apparatus according to claim 1 , wherein the cross-members are tubular. 3 . The apparatus according to claim 2 , wherein the frame is configured to support a mesh assembly formed of the tubular cross-members. 4 . The apparatus according to claim 3 , wherein the frame is also configured to support a mesh that is not configured to be heated. 5 . The apparatus according to claim 4 , wherein the tubular cross-members are arranged in a tier and are positioned generally parallel to each other. 6 . The apparatus according to claim 5 , wherein the tubes are arranged in two tiers such that the tubular cross-members in each tier are parallel to the tubular cross-members also in that tier and the tubular cross-members in each tier cross the tubular cross-members of the other tier to form a mesh. 7 . The apparatus according to claim 6 , wherein the mesh is configured to prevent foreign object debris from entering the air intake of the engine. 8 . The apparatus according to claim 7 , wherein the tubular cross-members are in a first-tier and solid wire links are positioned in a second-tier such that the first tier and the second tier together define a mesh. 9 . The apparatus according to claim 1 , wherein the aerodynamically efficient cross-section is teardrop shaped. 10 . The apparatus according to claim 9 , wherein a tail of the cross-section is narrow. 11 . The apparatus according to claim 9 , wherein a tail of the cross-section pointed. 12 . The apparatus according to claim 9 , wherein a tail of the cross-section is rounded. 13 . The apparatus according to claim 1 , wherein the aerodynamically efficient cross-section is generally diamond shaped. 14 . The apparatus according to claim 13 , wherein one end of the cross-section is general rounded. 15 . The apparatus according to claim 14 , wherein both ends of the cross section are rounded.
