Title (EN) AIRCRAFT FUSELAGE STRUCTURE COMPRISING AN ENERGY ABSORBING DEVICE
(FR) STRUCTURE DE FUSELAGE D'AÉRONEF COMPORTANT UN DISPOSITIF ABSORBEUR D'ÉNERGIE
Abstract: front page image
(EN)The invention relates to an aircraft fuselage structure comprising a circumferential reinforcing frame (2) and a plurality of stringers (3) substantially perpendicular to the frame. The frame comprises a mechanically weakened area capable of undergoing localised buckling under the effect of a compressive force exerted circumferentially thereon. The structure comprises an energy absorbing device (5) including two effector members (52) solidly connected to the frame on each side of the weakened area respectively and a central core (51) maintained between the effector members such that a reduction in the distance between the effector members produces a deformation of the central core which can absorb energy under the effect of said deformation.
(FR)L'invention concerne une structure de fuselage d'aéronef, comportant un cadre de renfort circonférentiel (2) et une pluralité de lisses (3) sensiblement perpendiculaires au cadre. Le cadre comporte une zone affaiblie mécaniquement apte à provoquer son flambage localisé sous l'effet d'un effort de compression exercé sur lui selon la direction circonférentielle. La structure comporte un dispositif dit absorbeur d'énergie (5) comportant deux organes effecteurs (52) solidaires du cadre respectivement de part et d'autre de la zone affaiblie, et un noyau central (51) maintenu entre les organes effecteurs de façon telle qu'une réduction de la distance entre les organes effecteurs induit une déformation du noyau central, ce dernier étant apte à absorber l'énergie sous l'effet de ladite déformation.
