A wing/fuselage connection for an aircraft, in which a wing (2) which is arranged in the upper area of the fuselage (1) is connected to the fuselage (1) by means of a number of connections (3, 4, 5, 6) with the connections (3, 4, 5, 6) being intended to absorb forces in different directions, and each having a maximum load carrying capacity which is designed in particular for a nominal flight and landing load (10) or for a nominal crash load. According to the invention, the load carrying capacity of the individual wing connections (3, 4, 5, 6) and their force absorption direction are matched to one another such that, if one of the connections (3, 4, 5, 6) is defective, the maximum load carrying capacity of the remaining connections (3, 4, 5, 6) is sufficient for safe normal flying operations.

L'invention concerne un assemblage aile-fuselage d'un avion, selon lequel une aile (2) disposée dans la région supérieure du fuselage (1) est assemblée au fuselage (1) au moyen d'un certain nombre de raccordements (3, 4, 5, 6). Les raccordements (3, 4, 5, 6) sont prévus pour absorber des forces dans des directions différentes et présentent chacun une capacité de charge maximale conçue notamment pour une sollicitation nominale en vol et au sol ou pour une sollicitation nominale en cas d'accident. Selon l'invention, la capacité de charge des différents raccordements (3, 4, 5, 6) de l'aile et leur direction d'absorption de forces sont mutuellement adaptées de telle sorte qu'en cas de défaillance d'un des raccordements (3, 4, 5, 6), la capacité de charge maximale des raccordements restants (3, 4, 5, 6) soit suffisante pour un fonctionnement normal en vol en toute sécurité.
