The invention relates to an aircraft wing, a fastening arrangement, and an intermediate support. A support structure of a wing (1) comprises transverse wing ribs (7a, 7b), between which an intermediate support (10) is arranged for providing a fastening point for a motor (9). The intermediate support comprises a vertical first side part (15a) and a vertical second side part (15b) which are at a distance from one another and connected to one another at their lower part by means of a horizontal bottom part (16) at least at a fastening lug (11). The lug is supported on the bottom part of the intermediate support.

What is claimed is: 1. An aircraft wing comprising: at least one front spar in the region of the front edge of the wing, at least one rear spar in the region of the trailing edge of the wing, a plurality of wing ribs between the front spar and the rear spar, top skin plates and bottom skin plates,
What is claimed is: 1. An aircraft wing comprising: at least one front spar in the region of the front edge of the wing, at least one rear spar in the region of the trailing edge of the wing, a plurality of wing ribs between the front spar and the rear spar, top skin plates and bottom skin plates, a plurality of stringers between the skin plates and the wing ribs, at least one intermediate support arranged between two adjacent wing ribs, at least one fastening lug for fastening a motor, the fastening lug being supported on the intermediate support and located on the side of the lower surface of the wing, and wherein the cross section of the intermediate support comprises a vertical first side part and a vertical second side part at a distance from one another, and wherein at least at the fastening lug there is a bottom part, which is attached to the lower parts of the side parts and is transverse to the side parts, and the fastening lug is fastened to the bottom part of the intermediate support. 2. A wing as claimed in claim 1, wherein in the section between the side parts the fastening lug is fastened to the bottom part of the intermediate support by means of a plurality of fastening bolts. 3. A wing as claimed in claim 1, wherein the upper edges of the first side part and those of the second side part curve towards the bottom part, when viewed from the side, whereby in the centre section the intermediate support extends a shorter distance upwards than at the wing ribs, and in the wing there is between the wing ribs a crawl space, which is defined in the height direction by the intermediate support and the top skin plate. 4. A wing as claimed in claim 1, wherein the fastening lug supported on the intermediate support is arranged to support the rear part of the motor of the aircraft. 5. A fastening arrangement in an aircraft, the fastening arrangement comprising: in an aircraft wing, a first support piece and a second support piece at a distance from the first support piece, at least one intermediate support, which is a longitudinal piece, the first end of which is fastened to the first support piece and the second end of which is fastened to the second support piece, at least one fastening point in the section between the first end and second end of the intermediate support, to which fastening point a fastening lug is fastened to direct a transverse load to the intermediate support, the intermediate support being arranged to transmit the load further to the support pieces of the wing, and wherein the cross section of the intermediate support comprises a vertical first side part and a vertical second side part at a distance from one another, and wherein at least at the fastening lug there is a bottom part, which is attached to the lower parts of the side parts and is transverse to the side parts, and the fastening lug is fastened to the bottom part of the intermediate support. 6. A fastening arrangement as claimed in claim 5, wherein at the fastening lug at least one reinforcing plate is arranged against the upper surface of the bottom part between the side parts, the fastening lug is fastened to the intermediate support by means of a plurality of fastening bolts, and the fastening bolts extend to the side of the upper surface of the reinforcing plate. 7. A fastening arrangement as claimed in claim 5, wherein the support pieces are wing ribs, and at its first end the intermediate support is fastened by means of fastening elements to the flank surface of the first wing rib and at its second end to the flank surface of the second wing rib. 8. A fastening arrangement as claimed in claim 5, wherein the upper edges of the first side part and those of the second side part curve towards the bottom part, when viewed from the side, whereby in the centre section the intermediate support extends a shorter distance upwards than at the support pieces. 9. A fastening arrangement as claimed in claim 5, wherein the intermediate support comprises two separate side components, namely the first side component and the second side component, each side component comprises a substantially vertical side part and a substantially horizontal bottom part, and the side components are connected to one another at least at their bottom parts. 10. A fastening arrangement as claimed in claim 5, wherein the intermediate support comprises two separate side components, namely the first side component and the second side component, each side component comprises a substantially vertical side part and a substantially horizontal bottom part, the side components are connected to one another at least at their bottom parts, the side components are made of a composite and manufactured with a similar mould, and the first side component is turned 180° with respect to the second side component before they are joined together. 11. A fastening arrangement as claimed in claim 5, wherein the upper edges of the first side part and second side part of the intermediate support comprise transverse broadening sections. 12. A fastening arrangement as claimed in claim 5, wherein at the fastening lug the free upper edges of the first side part and second side part of the intermediate support are supported on one another by means of at least one cover part, whereby the intermediate support has a closed, tube-like cross section at the fastening lug. 13. A fastening arrangement as claimed in claim 5, wherein the intermediate support is fastened to the support pieces by means of a plurality of separate fastening elements. 14. A fastening arrangement as claimed in claim 5, wherein the intermediate support is fastened to the support pieces by means of the fastening elements, which are integrated as parts of the side parts. 15. A fastening arrangement as claimed in claim 5, wherein at least the bottom part and side parts of the intermediate support are made of a composite material comprising at least one reinforcing fiber and at least one polymeric binder. 16. A fastening arrangement as claimed in claim 5, wherein the fastening arrangement is arranged to support the motor of the aircraft on the side of the lower surface of the wing. 17. An intermediate support for an aircraft wing, the intermediate support being a longitudinal piece and comprising: fastening elements at the first end and second end of the intermediate support, a fastening point in the section between the first end and the second end for fastening a fastening lug, and wherein the cross section of the intermediate support comprises a vertical first side part and a vertical second side part at a distance from one another, and wherein at least at the fastening point there is a bottom part, which is attached to the lower parts of the side parts and is transverse to the side parts, whereby the fastening lug may be fastened to the bottom part of the intermediate support, and wherein the upper edges of the first side part and those of the second side part curve towards the bottom part, when viewed from the side, whereby in the centre section the intermediate support extends a shorter distance upwards than at the ends.
