A method for producing a load introducing element for a control surface of an aircraft or a spacecraft, includes cutting to size preformed fibrous substructures out of a fibrous material. The method also includes draping the fibrous substructures to mold at least one first component, at least one second component and at least one first flange in the form of a single semi-finished product. Further, the method includes inserting the semi-finished product into a mold, injecting matrix material, and curing the semi-finished product to form a finished product.

1. A method for producing a load introducing element for a control surface of an aircraft or a spacecraft, said method comprising: cutting to size preformed fibrous substructures out of a fibrous material, wherein said load introducing element comprises at least one first component, at least one second component, and at least one first flange configured to connect to at least one structure of the control surface,at least one surface area of the first component has a contour that conforms to an inner contour of the control surface, andthe second component has at least one eye configured to receive a swing link or bearing link configured to mount the control surface;draping said fibrous substructures to mold the first component, the second component and the first flange in the form of a single semi-finished product;inserting the semi-finished product into a mold;injecting a matrix material; andcuring said semi-finished product to form a finished product, wherein the first component has an upper surface that is configured in such a manner that the first component lies flush with the inner contour of the control surface, andthe load introducing element is rigidly integrated into a structure of the control surface and fully surrounded by the control surface. 2. A method for producing a load introducing element for a control surface of an aircraft or a spacecraft, said method comprising: cutting to size preformed fibrous substructures out of a fibrous material;draping said fibrous substructures to mold at least one first component, at least one second component and at least one first flange in the form of a single semi-finished product;inserting the semi-finished product into a mold;injecting matrix material; andcuring said semi-finished product to form a finished product, wherein the at least one first flange connects to at least one rib of the control surface,at least one surface area of the first component is adapted to an inner contour of the control surface,the second component exhibits at least one eye for mounting the control surface, anda cross sectional profile of the first component has at least two substantially straight legs, which are connected together on their upper side via an upper edge, that is adapted to the contour of the control surface, wherein the at least one first component has an upper surface that is configured in such a manner that the at least one first component lies flush with the inner contour of the control surface, andthe load introducing element is rigidly integrated into a structure of the control surface and fully surrounded by the control surface. 3. The method as claimed in claim 2, further comprising arranging the first flange on at least one leg on an end of the first component that faces away from the upper edge. 4. The method as claimed in claim 2, further comprising forming the first flange and the first component by common layers of material. 5. The method as claimed in claim 2, further comprising enveloping the second component at least in certain areas by the first component. 6. The method as claimed in claim 2, wherein the second component has a greater wall thickness in an area comprising at least the one eye than in an area enveloped by the first component. 7. The method as claimed in claim 2, wherein the second component has a profile cross section that is substantially U shaped. 8. The method as claimed in claim 2, wherein the load introducing element further comprises at least one material layer which has a cross section that is L shaped, and which is applied simultaneously, at least in certain areas, on at least one element of the group consisting of the first component, the second component and the first flange. 9. The method as claimed in claim 2, further comprising integrating at least one wall plate into the at least one second component. 10. The method as claimed in claim 2, further comprising aligning at least one second flange substantially transversely to a direction of stretch of the load introducing element for attaching said load introducing element to load bearing structural components of the control surface. 11. The method as claimed in claim 2, wherein the first component has first and second flanges configured to be connected to a drive armature. 12. The method as claimed in claim 2, wherein the load introducing element is an integral component; and the first component, the second component, and at least the first flange comprise jointly impregnated and jointly cured pre-finished fibrous substructures. 13. The method as claimed in claim 2, further comprising driving the load introducing element with a drive armature, the drive armature including a drive armature rib configured to be connected to the load introducing element and a drive armature yoke configured to be connected to an actuator. 14. The method as claimed in claim 2, wherein when the control surface is viewed in cross-section, the control surface has an airfoil shape that includes an upper surface that is substantially non-linear and a lower surface that is substantially linear. 15. The method as claimed in claim 14, wherein the at least one surface area of the first component has a shape that is complimentary to the upper surface of the control surface. 16. The method as claimed in claim 15, wherein the cross sectional profile of the first component is substantially omega-shaped. 17. The method as claimed in claim 16, wherein a length of the at least one first flange is substantially equal to a length of the upper edge, andthe at least one first flange extends, from a side of the at least two substantially straight legs that is opposite to the upper side, in a direction that is substantially perpendicular to the at least two substantially straight legs.
