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.

1. A connection of an aerofoil to a fuselage airframe of an aircraft comprising a plurality of coupling members, in each case at least two z-coupling members which extend substantially parallel to a vertical axis of the aircraft and in each case at least two xz-coupling members being arranged in a region of two longitudinal edges of a fuselage airframe recess, wherein the spaces between the xz-coupling members and the z-coupling members are different and the xz-coupling members each comprising an xz-fuselage airframe bearing arranged on the fuselage airframe and an xz-aerofoil bearing attached to the aerofoil which are articulated to one another by two xz-straps which are inclined with respect to a longitudinal axis of the aircraft, wherein both longitudinal axes of the two xz-straps extend in an opposite inclination and with inclinations of different sizes with respect to a horizontal to compensate differing force effects, wherein the xz-straps of at least one xz-coupling member are configured such that, in the event of a crash, an energy-absorbing compression of the xz-straps occurs, as a result of which a side face of the xz-fuselage airframe bearing and a side face of the xz-aerofoil bearing are brought into direct mechanical contact, wherein the side faces are each provided with teeth which, in the event of a crash, mesh at least in a plurality of teeth, and wherein the xz-straps of the xz-coupling member comprise at least one of an elongate oval shape, a statically light configuration or have at least one weakened zone to allow a defined deformation of the xz-strap in the event of the aircraft crashing, so that impact energy is transferred by the xz-coupling member. 2. The connection according to claim 1, wherein a superficial shape of the side faces of the xz-fuselage airframe bearing and of the xz-aerofoil bearing are configured to be complementary to one another. 3. The connection according to claim 1, wherein in the region of the longitudinal edges at least two y-coupling members are arranged substantially parallel to a transverse axis of the aircraft. 4. The connection according to claim 1, wherein the at least two xz-straps are in an opposite and inclined arrangement with respect to a longitudinal axis of the aircraft in the region of a longitudinal edge. 5. The connection according to claim 1, wherein each xz-strap has two holes for two bolts. 6. The connection according to claim 1, wherein the z-coupling members each comprise a z-fuselage airframe bearing arranged on the fuselage airframe and a z-aerofoil bearing attached to the aerofoil. 7. The connection according to claim 3, wherein the y-coupling members each comprise a y-fuselage airframe bearing arranged on the fuselage airframe and a y-aerofoil bearing attached to the aerofoil which are articulated to one another by two y-straps with two holes and two bolts. 8. The connection according to claim 1, wherein longitudinal axes of two xz-straps intersect one another in the region of a longitudinal edge. 9. The connection according to claim 1, wherein the coupling members are preferably formed using at least one of titanium alloy or titanium. 10. The connection according to claim 1, wherein the two xz-straps have at least one weakened zone to allow a defined deformation of the xz-strap in the event of the aircraft crashing. 11. The connection according to claim 1, wherein the connection is a connection of a high-wing aircraft.
