Patent ID: 7506838

Claim:
Stiffening frame for an air intake structure for an aircraft engine, comprising a first end portion, an intermediate portion, and a second end portion, the intermediate portion being an inflection portion such that in a section orthogonal to the end portions, the frame approximately defines a first straight line between the first end portion and the intermediate portion, and it defines a regular non-null curve between the second end portion and the inflection portion, the tangent to the curve at the second end portion being perpendicular to the first plane corresponding to the first straight line, the height of the stiffening frame defined between the first end portion and the normal projection of the second end portion onto the first plane being between a first height and, when the stiffening frame is compressed by a force with a component which is perpendicular to the direction of the second end portion and in the first plane, a second height at least 20% less than the first height.
