METHOD FOR PRODUCING A SEALED FRONT END OF AN AIRCRAFT FUSELAGE AND FUSELAGE EQUIPPED WITH SUCH A SEALED END

摘要

The invention aims to produce a sealed end comprising a limited number of parts while producing an optimised compromise between energy absorption and rigidity in such a way as to be able to resist violent shocks caused by the impact of foreign bodies, in particular birds. A sealed end (1) according to the invention comprises a stiffener panel (11) configured according to a double orientation and assembled by embedding in and rigid attachment to a shield of porous material (12), at least partially slotted in the thickness of same, according to a complementary configuration. The thus combined assembly is arranged between a closing wall (13) at one end (A) and a peripheral framework (15) for attachment to the fuselage (2) of the aircraft at the other end (B), the closing wall (13) being rigidly attached to the porous shield (12) and the stiffener panel (11) being rigidly attached to the peripheral attachment framework (15) via a sealing gasket (14).
