A removable plate and a flange that occupies a hole in a panel. The flange has the particular feature of taking up compressive force to which the panel is subjected in its plane, perpendicularly to the hole. The weight of the device used to equip the hole is reduced, and the mechanical behavior of the panel at the position of the hole is improved.

What is claimed is: 1. A device for reinforcing a panel of an aircraft structure, wherein the panel presents a panel plane, the panel further presenting a panel first face, an opposed panel second face, a panel thickness extending between the panel first face and the panel second face, and structure defining a panel hole and a panel hole edge extending the panel thickness transverse to the panel plane, the device being removably engageable with the panel at the panel hole, the device comprising: a plate including a plate section and a plate fin; and a flange removably coupled to the plate, the flange including a flange section having a flange section thickness being less than said panel thickness, and receivable within the panel hole and engageable with the panel hole edge, a flange fin oriented radially outwardly from the flange section, and a peripheral reinforcement portion intermediate the flange section and the flange fin, wherein the peripheral reinforcement portion is positioned substantially flush against the panel hole edge, the peripheral reinforcement portion being adapted to absorb a compressive force from the panel hole edge, the peripheral reinforcement portion presenting a peripheral reinforcement portion thickness being greater than said flange section thickness, wherein the plate fin is oriented relative to the plate section and the flange fin is oriented relative to the flange section such that the plate fin abuts the panel first face, and the flange fin abuts the opposed panel second face such that the flange fin and plate fin clampingly engage the panel when the device is removable engaged with the panel at the panel hole. 2. The device according to claim 1, wherein the flange of the device occupies the hole of the panel with a minimum clearance that is filled by the deformation of the panel when it is subjected to compression, such as when the aircraft is in flight. 3. The device according to claim 1, wherein the panel hole comprises an oval shape and the compressive force is collinear with a major axis of the panel hole. 4. The device according to claim 3, wherein the ratio of the major axis of the hole to a minor axis of the hole is two. 5. The device according to claim 1, wherein the flange section further defines a hole. 6. An aircraft panel reinforced with the device according to claim 1. 7. The aircraft panel according to claim 6, wherein the panel is synthetic resin. 8. The aircraft panel according to claim 6, wherein the panel is formed by composite materials. 9. The aircraft panel according to claim 6, wherein the panel is formed by a sheet of carbon fibers. 10. The aircraft panel according to claim 6, wherein the panel is formed by a sheet of stratified materials. 11. The device according to claim 1, wherein the flange section is adapted to take up force, and wherein the flange section weaker than the panel, and is placed in the middle of the two faces of the panel. 12. The device according to claim 1, wherein at least one of the plate fin and the flange fin includes a seal. 13. The device according to claim 1, wherein the plate fin is coupled to the plate by a fillet joint. 14. The device according to claim 1, wherein the flange fin is coupled to the peripheral reinforcement portion of the flange by a fillet joint. 15. The device according to claim 1, wherein the flange section is adapted to take up force, and wherein flange section is weaker than the panel and is offset towards one of two faces of the panel. 16. The device according to claim 1, wherein the removable plate and the flange of the device are made of aluminum, titanium, or composite material. 17. The device according to claim 1, wherein the flange of the device is operably coupled to the removable plate by screwing or bonding. 18. The device according to claim 1, wherein the panel comprises a rabbet at the position where at least one of the removable plate and the flange are mounted thereto. 19. The device according to claim 1, wherein the peripheral reinforcement portion comprises structure defining perforations having attachment screws engaged therein, thereby removably coupling the flange to the plate. 20. A system for reinforcing a panel of an aircraft structure, the system comprising: a panel presenting a panel plane, the panel further presenting a panel first face, an opposed panel second face, a panel thickness extending between the panel first face and the panel second face, and structure defining a panel hole and a panel hole edge extending the panel thickness transverse to the panel plane; a plate including a plate section and a plate fin, the plate fin being operably coupled to the first face of the panel at the panel hole edge; and a flange removably coupled to the plate, the flange including a flange section having a flange section thickness being less than said panel thickness, and received within the panel hole and removably engaged with the panel hole edge, a flange fin oriented radially outwardly from the flange section and operably coupled to the opposed panel second face, and a peripheral reinforcement portion intermediate the flange section and the flange fin, wherein the peripheral reinforcement portion is positioned substantially flush against the panel hole edge, the peripheral reinforcement portion being adapted to absorb a compressive force from the panel hole edge, the peripheral reinforcement portion presenting a peripheral reinforcement portion thickness being greater than said flange section thickness wherein the plate fin is oriented relative to the plate section, and the flange fin is oriented relative to the flange section such that the plate fin abuts the panel first face, and the flange fin abuts the opposed panel second face such that the flange fin and plate fin clampingly engage the panel when the device is removably engaged with the panel at the panel hole. 21. The system according to claim 20, wherein the peripheral reinforcement portion comprises structure defining perforations having attachment screws engaged therein, thereby removably coupling the flange to the plate.
