Abstract
Official abstract text for this publication.
An assembly of longitudinal structural stiffeners for an aircraft including, in a front portion of the fuselage, a windscreen that is slightly recessed relative to the airplane nose, and a fuselage portion extending in alignment with the airplane nose up to the base of the windscreen. The stiffeners include a bending-resistance main plane and are arranged under the flap and connected to the fuselage along a force transfer line. For one or more of the stiffeners, the bending resistance main plane substantially coincides, at at least a certain number of points of the fuselage force transfer line, with the plane predetermined by the local normal to the fuselage surface and the longitudinal axis of the airplane. A method is also provided for calculating the shape of the stiffeners.
First claim
Opening claim text (preview).
The invention claimed is: 1. An assembly comprising: a fuselage surface; and a plurality of longitudinal structural stiffeners, the stiffeners comprising a main plane of bending resistance substantially perpendicular to the fuselage surface, being positioned below a portion of the fuselage surface and secured to the fuselage surface along a force transfer line; wherein, for plural of the stiffeners, the main plane of bending resistance of the stiffener substantially coincides,…
