The invention claimed is: 1. Reinforced cover for gaps in an aerodynamic contour of a vehicle, particularly for an aircraft, comprising: a first section for securing the cover to an external panel of a structural element of the vehicle by attachment means, the external panel having an inner surface
The invention claimed is: 1. Reinforced cover for gaps in an aerodynamic contour of a vehicle, particularly for an aircraft, comprising: a first section for securing the cover to an external panel of a structural element of the vehicle by attachment means, the external panel having an inner surface and an outer surface, a flexible second section being tongue-shaped and having an extension that at least partially covers a gap between the external panel and a moving part of the vehicle and with a free end which ends on said moving part, the second section having an inner surface and an outer surface, reinforcement means, and a low-friction layer which at least partially covers the inner surface of said second section, the first section being secured on the inner surface of the external panel and the outer surface of the second section flushing with the outer surface of the external panel as a continuation of the outer surface of the external panel; the reinforcement means comprising a reinforcement member with at least one fiberglass layer in epoxy resin having a thickness and formed at the outer surface of the first section and at least in one adjacent area to said first section of the outer surface of said second section; said reinforcement member in the first section having an under surface and extending substantially in a first axial plane and in the second section extending substantially in a second axial plane, said first axial plane being different from said second axial plane; and an elastic member connected to the under surface of the reinforcement member on at least the adjacent area of the second section. 2. Reinforced cover according to claim 1, wherein the fiberglass layer comprises a plurality of piled-up and glued-together fiberglass cloths, the thickness of the fiberglass layer being determined by the number of piled-up fiberglass cloths. 3. Reinforced cover according to claim 2, wherein the fiberglass layer comprises a larger number of piled-up glass cloths in areas of said first and said second section which are exposed to greater stresses, than in areas subjected to lesser stresses. 4. Reinforced cover according to claim 2, wherein the fiberglass layer comprises a larger number of piled-up fiberglass cloths in said first section and in said adjacent area of the second section that in other sections of the cover. 5. Reinforced cover according to claim 2, wherein the number of piled-up fiberglass cloths in the second section decreases in the direction towards the free end of said second section. 6. Reinforced cover according to claim 2, wherein the number of piled-up fiberglass cloths in said adjacent area decreases progressively up to the free end of the second section. 7. Reinforced cover according to claim 1, wherein the thickness of the fiberglass layer is greater at areas of said first and said second section which are exposed to greater stresses, than in areas subjected to lesser stresses. 8. Reinforced cover according to claim 1, wherein the thickness of the fiberglass layer in said first section and in said adjacent area of the second section is greater than the thickness of the fiberglass layer in other sections of the cover. 9. Reinforced cover according to claim 1, wherein the thickness of the fiberglass layer on the second section decreases in the direction towards the free end of said second section. 10. Reinforced cover according to claim 1, wherein the thickness of the fiberglass layer on said adjacent area decreases progressively towards the free end of the second section. 11. Reinforced cover according to claim 1, wherein a transition section extends along a slanted longitudinal axis which extends from said first axial plane to said second axial plane. 12. Reinforced cover according to claim 11, wherein in said adjacent area, the elastic member is of a thickness which progressively increases in said transition section and decreases in the direction towards free end of said second section. 13. Reinforced cover according to claim 1, wherein the free end of the second section has, at least partially, a lower protruding edge which contacts with the outer surface of said moving part of the vehicle. 14. Reinforced cover according to claim 13, wherein the lower protruding edge has a convexly curved cross-section. 15. Reinforced cover according to claim 1, wherein the material of the elastic member is silicone rubber. 16. Reinforced cover according to claim 1, wherein the low-friction layer is made of polyester fabric. 17. Reinforced cover according to claim 1, wherein said first section is shaped in the form of an attachment tab. 18. Reinforced cover according to claim 1, wherein at least the outer surface of said second section is coated with paint. 19. Reinforced cover according to claim 1, wherein the outer surface of the cover is coated with paint. 20. Reinforced cover according to claim 1, wherein the first attachment section comprises at least one through hole for receiving the attachment means. 21. Reinforced cover according to claim 20, wherein the attachment means are selected from rivets, nut-bolt assemblies and bolt-rivetable nut assemblies. 22. Reinforced cover according to claim 1, wherein said adjacent area of the second section comprises a flexible transition section between said first section and said second section, the outer surface of the second section flushes with the outer surface of the external panel of the vehicle and extends towards the free end as a continuation of of the external panel said outer surface.
