Embodiment Construction

[0028] Now that the objects of the present invention have been indicated, specific non-limiting embodiments are described below.

[0029] exist Figure 1A An embodiment of an aircraft is shown in , and is shown provided with FTAC ( Figure 1C ) of the position Figure 1B The left wing of the aircraft is shown in . exist Figure 1D , a cross-sectional view of the inner area of ​​the wing where the fuel tank 1 is provided is shown. In addition, in Figure 1D with Figure 1E In , the relative position of FTAC and fuel tank 1 is shown. The inner FTAC 3 is located in the fuel tank 1 and is sealed to the lower wing skin 16 by a fuel seal 17 . The outer FTAC 4 is secured to the lower wing skin 16 by means of a plurality of mounting holes distributed along the periphery. In an embodiment of the invention, the fixing means 18 or fasteners are bolts.

[0030] In an embodiment of the invention, the outer FTAC 4 comprises energy absorbing means which is at least one frangible wire...

Abstract

The present invention describes an outer fuel access tank cover (FTAC) of an aircraft, a wing comprising such outer FTAC of an aircraft and an aircraft. The invention belongs to the field of designing auxiliary pieces in the wings of aircraft to control the risk of impact against an inner FTAC when an impact occurs against the outer FTAC. This impact can be caused by a tire.

Description

technical field [0001] The present invention describes an aircraft outer fuel tank access cover (FTAC), an aircraft wing comprising such an outer FTAC, and an aircraft. The present invention belongs to the field of designing auxiliary components in the wings of aircraft to control the risk of impact on the inner FTAC in the event of an impact on the outer FTAC. This shock can be caused by the tire. Background technique [0002] Manholes in the aircraft provide access to the fuel tanks. The access hole consists of the inner fuel tank access cover (inner FTAC), the outer FTAC and the hollow area between the two covers. Fuel tank access covers (FTACs) are mechanically fastened with fasteners such as bolts and clamped against the aircraft wing skin to provide a seal to the fuel tank access opening. FTACs are designed to meet a wide range of needs, some of these needs are: no fuel leaks, fire protection, tire shock protection, resistance to damage caused by UERF (Uncontrolled ...
