The invention pertains to a fuselage cell structure for an aircraft of hybrid construction, wherein the fuselage cell structure is composed of a plurality of skin panels (2, 3, 30-32, 42, 43, 70, 71), longitudinal braces (53, 88, 89) and transverse braces, particularly frames (18, 59), such that a plurality of longitudinal and/or transverse seams (1, 29, 41, 77, 83) are created. At least one skin panel (2, 31, 32, 71) is realized with a double- shell and at least one skin panel (3, 30, 43, 70) is realized monolithically. According to the invention, at least one longitudinal bracket (10, 81, 82) with a first and a second longitudinal flange (11, 12) is provided in the region of the at least one longitudinal seam 1, 83 between a monolithic and a double-shell skin panel (2, 3, 70, 71), wherein the longitudinal flanges (11, 12) are connected offset to one another by means of an inclined suitable web 13. At least one load transfer point (34, 56, 90, 91) is provided in the region of the at least one transverse seam (29, 41, 77) between a monolithic and a double-shell skin panel (30, 31, 32, 42, 43, 70, 71) in order to connect at least one longitudinal brace (53, 88, 89) situated on the monolithic skin panel (43, 70) to the at least one double- shell skin panel (42, 71). Due to the longitudinal brackets (10, 82), a connection that is optimized with respect to the flow of loads is produced between a monolithic and a double-shell skin panel (2, 3, 70, 71), wherein the core structure (4, 74) of the double-shell skin panel (2, 71) is at the same time laterally closed. The load transfer points (29, 41, 90, 91) in the region of the transverse seams (29, 41, 77) ensure an effective introduction of the loads originating from longitudinal braces (53, 88, 89) into the double-shell skin panels (31, 32, 42, 71), wherein an additional reinforcement and at the same time a border of the otherwise open core structure (44, 74) can be realized by means of an optional transverse bracket (37, 49, 84).
L'invention concerne une structure cellulaire de fuselage de construction hybride pour un avion, composée d'une pluralité de panneaux extérieurs (2, 3, 30-32, 42, 43, 70, 71), de renforts longitudinaux (53, 88, 89) et de renforts transversaux, notamment de couples (18, 59), avec création d'une pluralité de joints longitudinaux et/ou transversaux (1, 29, 41, 77, 83). Au moins un panneau extérieur (2, 31, 32, 71) est conçu de façon double coque et au moins un panneau extérieur (3, 30, 43, 70) est conçu de façon monolithique. La zone de la ou des joints longitudinaux (1, 83) comporte, entre un panneau extérieur monolithique et un panneau extérieur double coque (2, 3, 70, 71), au moins un collier longitudinal (10, 81, 82) pourvu d'une première et d'une deuxième bride longitudinale (11, 12) reliées de façon décalée au moyen d'une entretoise inclinée (13). La zone de la ou des joints transversaux (29, 41, 77) comporte, entre un panneau extérieur monolithique et un panneau extérieur double coque (30, 31, 42, 43, 70, 71), au moins un élément de transfert de charge (34, 56, 90, 91) pour la liaison d'au moins un renfort longitudinal (53, 88, 89) situé sur le panneau extérieur monolithique (43, 70), à ou aux panneaux double coque (42, 71). Les colliers longitudinaux (10, 82) permettent une liaison autorisant le flux de charge entre un panneau extérieur monolithique et un panneau extérieur double coque (2, 3, 70, 71), la structure centrale (4, 74) du panneau extérieur double coque (2, 71) étant par ailleurs fermée latéralement. Les éléments de transfert de charge (29, 41, 90, 91) au niveau des joints transversaux (29, 41, 77) garantissent une application de force efficace des forces issues des renforts longitudinaux (53, 88, 89), aux panneaux extérieurs double coque (31, 32, 42, 71), un collier transversal optionnel (37, 49, 84) permettant d'obtenir une rigidification supplémentaire et une fermeture de la structure centrale (44, 74) qui est ouverte en l'absence dudit collier.
