Title (EN) SEALING DEVICE FOR AIRCRAFT TURBOJET ENGINE NACELLE
(FR) Dispositif d'étanchéité pour nacelle de turboréacteur d'aéronef
Abstract:
(EN) The invention relates to a sealing device (6) for an aircraft turbojet engine nacelle, comprising a seal (61) provided with a tubular part (611), a support element (62) accepting this seal (61) in a sealing position, and an attachment system (63). The attachment system (63) comprises a retainer (631) inside the tubular part (611) acting as an end stop for the seal (61) and a fastener (632) of the locking wire type securing the retainer (631) to the support element (62) in such a way as to keep the seal (61) in the sealing position. The sealing device (6) may comprise a plurality of end stops and of fasteners.
(FR) Dispositif d'étanchéité pour nacelle de turboréacteur d'aéronef L'invention se rapporte à un dispositif d'étanchéité(6) pour nacelle de turboréacteur d'aéronef comprenant un joint (61) doté d'une partie tubulaire (611), un élément de support (62) recevant ce joint (61) dans une position d'étanchéité, ainsi qu'un système d'attache (63).Le système d'attache (63) comporte une pièce de maintien (631) à l'intérieur de la partie tubulaire (611) formant une butée pour le joint (61) et une attache(632) de type fil-frein solidarisant la pièce de maintien (631) à l'élément de support (62) de manière à maintenir le joint (61) dans la position d'étanchéité. Le dispositif d'étanchéité (6) peut comprendre plusieurs butées et attaches.
