First Claim
Patent Images
1. An air intake assembly of an aircraft having an outer skin, the outer skin having a contour, the air intake assembly comprising:
- an air filter assembly including;
an exterior surface that conforms to the contour of the aircraft; and
a lip secured to the outer skin and substantially flush with the outer skin;
a pressure recovery device including;
a flange, wherein the lip is secured between the flange and the outer skin, wherein the flange, the lip, and the outer skin are substantially parallel, and wherein the flange includes openings extending therethrough and aligned with openings defined respectively in the lip and the outer skin; and
an outer wall spaced from the exterior surface of the air cleaning assembly, wherein a distance from a forward edge of the outer wall to the air cleaning assembly is greater than a distance from an aft edge of the outer wall to the air cleaning assembly; and
fasteners received in the aligned openings in the flange, the lip, and the outer skin for securing both the pressure recovery device and the air filter assembly to the aircraft.
