Patent

CA 2755657

The invention relates to an assembly of longitudinal structural stiffeners for an aircraft comprising, in the front portion of the fuselage, a windscreen that is slightly recessed relative to the airplane nose, a fuselage portion (flap) extending in alignment with the airplane nose up to the base of the windscreen, said stiffeners being of the kind that comprise a bending-resistance main plane and being arranged under the flap and connected to the fuselage along a force transfer line, characterised in that for one or more of said 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 XNi predetermined by the local normal Ni to the fuselage surface and the longitudinal axis X of the airplane. The invention also relates to a method for calculating the shape of the stiffeners.

L'ensemble de raidisseurs structurels longitudinaux, pour un aéronef comportant dans la partie avant de son fuselage, un pare-brise, en léger retrait par rapport au nez de l'avion, une partie du fuselage (bavette) venant dans le prolongement du nez de l'avion jusqu'au pied du pare-brise,lesdits raidisseurs, du type comportant un plan principal de résistance à la flexion, étant disposés sous la 5 bavette et solidarisés au fuselage le long d'une ligne de reprise d'effort, est caractérisé en ce que pour un ou plusieurs desdits raidisseurs, le plan principal de résistance à la flexion du raidisseur se confond sensiblement, en au moins un certain nombre de points de sa ligne de reprise d'effort au fuselage, avec le plan XNi déterminé par la normale locale Ni à la surface du fuselage et l'axe 10 longitudinal X de l'avion. L'invention vise également le procédé de calcul de la forme des raidisseurs.
