Abstract

The present invention describes an outer fuel tank access cover (4) (FTAC) of an aircraft comprising an explosion gas relief means (8) adapted for letting the explosion gases escape to the atmosphere, a wing comprising such outer FTAC (4) of an aircraft and an aircraft. The invention belongs to the field of designing auxiliary pieces in the wing of aircraft to control the risk of gases from an explosion occurred in the FTAC entering the fuel tank.

Description

technical field [0001] The present invention describes an outer fuel access tank cover (FTAC) of an aircraft, a wing including the further FTAC of the aircraft, and the aircraft. The invention belongs to the field "Design of auxiliary components in the wing of an aircraft to control the risk of gas entering the fuel tank from a deflagration occurring in an FTAC". Background technique [0002] Manholes in the aircraft provide access to the fuel tanks. The manhole includes an inner fuel tank access cover (inner FTAC), an outer FTAC, and a void area between the two covers. A fuel tank access cover (FTAC) is mechanically fastened and clamped to the aircraft wing skin to provide a fuel tank access seal. FTACs are designed to meet a wide range of requirements, some of which are: no fuel leaks, fire protection, resistance to crashes caused by UERF (Uncontained Engine Rotor Failure Fault), EMH / lightning strike, seal friction, and airfoil bending. In addition to the "no fuel leak...
