A wing-fuselage connection of an aircraft, in which a wing (2) that is arranged in the upper region of the fuselage (1) is connected to the fuselage (1) by means of a number of couplings (3, 4, 5, 6), wherein the couplings (3, 4, 5, 6) are provided for taking up forces in various directions and are
A wing-fuselage connection of an aircraft, in which a wing (2) that is arranged in the upper region of the fuselage (1) is connected to the fuselage (1) by means of a number of couplings (3, 4, 5, 6), wherein the couplings (3, 4, 5, 6) are provided for taking up forces in various directions and are designed for a maximum load carrying capacity, in particular for a nominal flight- and landing load (10) or a nominal crash load. According to the invention, the load carrying capacity of the individual wing couplings (3, 4, 5, 6) and their direction of force take-up are matched to each other such that in the case of a defect in one of the couplings (3, 4, 5, 6) the maximum load carrying capacity of the remaining couplings (3, 4, 5, 6) is adequate for safe normal flight operation.
