Abstract
A stiffener for a structure submitted to tensile and/or compression and/or shear stresses, that includes a shaped section including: a contact area with an element to be stiffened having a closed cross-section and providing stability, the aforementioned area including first and second legs; and a core normal to the element to be stiffened that provides a support surface capable of element recovery, the aforementioned core being formed by one of the two legs. Application in aircraft structures.
Claims11
A stiffener for a structure subject to tensile and/or compressive and/or shearing stresses, the stiffener having a λ-shaped section that includes:
- a contact area configured to connect the stiffener to the structure, the contact area comprising a first surface area and a second, spaced apart, surface area, both surface areas lying in the same plane;
- the first and second surface areas of the contact area respectively having a first and a second leg extending therefrom, which legs come together at a junction forming an overlap, the first leg being a long leg and the second leg being a short leg, and the legs and the plane in which the first and second surface areas lie defining a closed cross section, and
- a core extending perpendicular to the plane in which the contact area lies, giving the stiffener a supporting surface for mounting an element;
- the core being made up of one of the two legs.
