A fixed wing of an aircraft, having a main wing extending over a half-span with a wing box including spars extending along the spanwise direction of the main wing, ribs arranged one in back of the other viewed in the spanwise direction, and an outer skin. The wing box includes a wing box base section (K10) and a wing box adapter section, that forms the outer end area of the wing box, as viewed from the wing root, and is designed to secure a wing tip device. In its nominal state of construction, the dihedral angle of the wing box adapter section referring to the respective local spanwise direction continuously increases by at most 60 degrees from the outer rib of the wing box base section (K10) up to the outermost rib of the wing box adapter section.

1. A wing of an aircraft that exhibits a main wing extending over a half-span, wherein a wing chord of the main wing (M) at a location of an outermost rib (R5) of the main wing (M) viewed from the wing root measures 5% to 15% of the half-span of the main wing (M),wherein the main wing (M) is compris
1. A wing of an aircraft that exhibits a main wing extending over a half-span, wherein a wing chord of the main wing (M) at a location of an outermost rib (R5) of the main wing (M) viewed from the wing root measures 5% to 15% of the half-span of the main wing (M),wherein the main wing (M) is comprised of a wing base area (10) and a wing adapter section (20), that forms the outer end area of the main wing (M), as viewed from the wing root, and is designed to secure a wing tip device (W1, W2, W3),wherein the wing adapter section (20) extends from an outer rib (R3) of the wing base area (10) and over 2% to 10% of the half-span of the main wing (M) up to an outer rib (R5) of the wing adapter section (20) forming the outermost rib (R5) of the main wing (M),characterized in that the dihedral angle of the wing adapter section (20) that refers to the respective local spanwise direction continuously increases by between 10 and 60 degrees from the outer rib (R3) of the wing base area (10) up to the outermost rib (R5) of the wing adapter section (20). 2. The wing according to claim 1, characterized in that the wing adapter section (20) is an integral part of the main wing (M). 3. The wing according to claim 1, characterized in that the wing adapter section (20) is a separate part of the main wing (M) attached thereto. 4. The wing according to claim 1, characterized in that the main wing (M) comprises a wing box (K) comprised of spars extending along the spanwise direction of the main wing (M), a plurality of ribs (R1, R2, R3, R4, R5) arranged one after another viewed in the spanwise direction, and an outer skin, wherein the wing chord of the main wing (M) at the location of the outermost rib (R5) of the main wing (M) viewed from the wing root measures 5% to 15% of the half-span of the wing box (K),wherein the wing box (K) is comprised of a wing box base section (K10) and a wing box adapter section (K20), that forms the outer end area of the wing box (K), as viewed from the wing root, and is designed to secure a wing tip device (W1, W2, W3),wherein the wing box adapter section (K20) extends from an outer rib (R2) of the wing box base section (K10) and over 2% to 10% of the half-span of the wing box (K) up to an outer rib (R5) of the wing box adapter section (K20) forming the outermost rib (R5) of the main wing, characterized in that the dihedral angle of the wing box adapter section (K20) that refers to the respective local spanwise direction continuously increases by between 10 and 60 degrees from the outer rib (R2) of the wing box base section (K10) up to the outermost rib (R5) of the wing box adapter section. 5. The fixed wing according to claim 1, characterized in that the local sweep of the leading edge of the fixed wing in its nominal state of construction increases by between 10 and 45 degrees in the area of the wing box adapter section. 6. The fixed wing according to claim 1, characterized in that the outer end of the wing box adapter section (K20) has a connection device for securing a wing tip device. 7. The fixed wing according to claim 1, characterized in that the wing box adapter section that forms the outer end area of the wing box is designed for the attachment of a wing tip device, wherein the wing tip device with an inner rib is joined to an outer rib of the wing box base section (K10). 8. The fixed wing according to claim 6, characterized in that the connection device is designed as a positive-locking part on the outer end as viewed from the wing root, so as to positively attach a wing tip device to be coupled with the wing box adapter section to the wing box adapter section. 9. The fixed wing according to claim 1, characterized in that the local sweep of the leading edge of the fixed wing increases by at most 45 degrees in the area of the wing box adapter section. 10. The fixed wing according to claim 1, characterized in that the local sweep of the trailing edge of the fixed wing increases by at most 5 degrees in the area of the wing box adapter section. 11. The fixed wing according to claim 1, characterized in that the local sweep of the trailing edge of the fixed wing increases by at most 20 degrees in the area of the wing box adapter section. 12. The fixed wing according to claim 1, characterized in that the outer end of the wing box base section (K10) as viewed from the wing root along with the inner end of the wing box adapter section (K20) adjacent thereto each have a connection device for coupling the wing box adapter section to the wing box base section (K10). 13. The fixed wing according to claim 12, characterized in that the coupling device is designed in such a way that, in order to create the connection device, the outer rib of the wing box base section (K10) and the inner rib of the wing box adapter section each have boreholes, and that connection elements are provided for securing the outer rib to the inner rib so as to couple the main wing box section (K10) with the wing box adapter section. 14. The fixed wing according to claim 13, characterized in that the coupling device is designed in such a way as to be separated by destroying the connection elements. 15. The fixed wing according to claim 13, characterized in that the connection is configured in such a way that the coupling device is designed in such a way as to be separated without any destruction. 16.
