Title
(EN) IMPROVED AIR-SEALING DEVICE INTENDED TO BE INSERTED BETWEEN AN AIRCRAFT DUAL-FLOW TURBINE ENGINE CASING ELEMENT AND A NACELLE ELEMENT
(FR) DISPOSITIF AMELIORE D'ETANCHEITE A L'AIR DESTINE A ETRE INTERPOSE ENTRE UN ELEMENT DE CARTER DE TURBOMACHINE D'AERONEF A DOUBLE FLUX, ET UN ELEMENT DE NACELLE
Abstract
(EN)
The invention concerns an air-sealing device (40) intended to be inserted between an aircraft dual-flow turbine engine casing element (16) and a nacelle element (30), the sealing device comprising an attachment tab (42) at the end of which is located a sealing portion (44) having an outer surface intended to be contacted by the casing element and the nacelle element, and an inner surface defining a cavity. The inner surface defines at least one protuberance extending inside the cavity.
(FR)
L'invention concerne un dispositif d'étanchéité à l'air (40) destiné à être interposé entre un élément de carter (16) de turbomachine d'aéronef à double flux et un élément de nacelle (30), le dispositif d'étanchéité comprenant une languette de fixation (42) à l'extrémité de laquelle se trouve une portion d'étanchéité (44) présentant une surface extérieure destinée à être contactée par l'élément de carter et l'élément de nacelle, et une surface intérieure délimitant un creux. La surface intérieure définit au moins une protubérance s'étendant à l'intérieur du creux.
