An aerofoil connection on a fuselage airframe comprising a plurality of double-jointed coupling members. In each case at least two z-coupling members extending substantially parallel to a vertical axis of the aircraft and in each case at least two xz-coupling members are arranged in the region of two longitudinal edges of a fuselage airframe recess wherein the xz-coupling members are configured in each case for a first maximum of a load in the event of a crash and of a load in normal flight operation parallel to a longitudinal axis of the aircraft, and for a second maximum of a load in the event of a crash and of a load in normal flight operation parallel to the vertical axis. The xz-coupling members are capable of absorbing force components parallel to the x-axis as well as force components which arise parallel to the z-axis.
Connection (12, 15) of an aerofoil (7, 13) to a fuselage airframe (1, 14) of an aircraft, in particular a high-wing aircraft, comprising a plurality of coupling members (8-11, 16-21), in each case at least two z-coupling members (8, 11, 16, 17) which extend substantially parallel to a vertical axis (z) of the aircraft and in each case at least two xz-coupling members (9, 10, 20, 21) being arranged in the region of two longitudinal edges (4, 5) of a fuselage airframe recess (3), characterised in that the xz-coupling members (9, 10, 20, 21) are configured in each case for a first maximum of a load in the event of a crash and of a load in normal flight operation parallel to a longitudinal axis (x) of the aircraft, and for a second maximum of a load in the event of a crash and of a load in normal flight operation parallel to the vertical axis (z).
Method for the construction of a connection (12, 15) of an aerofoil (7, 13) to a fuselage airframe (1, 14) of an aircraft, in particular a high-wing aircraft, which connection (12, 15) has a plurality of coupling members (8-11, 16-21), wherein in each case at least two z-coupling members (8, 11, 16, 17) extending substantially parallel to a vertical axis of the aircraft and in each case at least two xz-coupling members (9, 10, 20, 21) are arranged in the region of two longitudinal edges (4, 5) of a fuselage airframe recess (3), comprising the following steps:
