Abstract

L'invention concerne un ensemble de propulsion (200) pour un aéronef, ledit ensemble de propulsion (200) comportant : - un mât réacteur (20), - une nacelle fixée au mât réacteur (20) et comportant au moins un capot (22) monté mobile au voisinage du mât réacteur (20), et - un joint (100) disposé entre le mât réacteur (20) et le capot (22), l'ensemble de propulsion (200) étant caractérisé en ce que le joint (100) présente successivement: - une première extrémité (104) qui est libre, prévue pour venir en appui sous le capot (22), et orientée à l'opposé du mât réacteur (20), - une partie rectiligne (110), - une partie rayonnée (108), et - une deuxième extrémité (102) orientée vers la première extrémité (104) et fixée au mât réacteur (20). Les contraintes induites dans le joint (100) sont réparties sur l'ensemble de la partie rayonnée (108) ce qui permet une plage de déplacement du joint (100) plus importante.The invention relates to a propulsion assembly (200) for an aircraft, said propulsion assembly (200) comprising: - an engine pylon (20), - a nacelle fixed to the engine pylon (20) and comprising at least one cowl (22) ) mounted movably in the vicinity of the reactor mast (20), and - a seal (100) disposed between the reactor mast (20) and the cowl (22), the propulsion assembly (200) being characterized in that the seal ( 100) successively presents: - a first end (104) which is free, intended to come to rest under the cover (22), and oriented opposite the engine mast (20), - a rectilinear part (110), - a radiated part (108), and - a second end (102) oriented towards the first end (104) and fixed to the reactor mast (20). The stresses induced in the seal (100) are distributed over the whole of the radiated part (108) which allows a greater range of movement of the seal (100).
