Abstract

NACELLE D’UN TURBOREACTEUR COMPORTANT UN VOLET INVERSEUR ET UN SYSTEME DE DEPLOIEMENT A RETARDEMENT L’invention concerne une nacelle (102) comportant une structure fixe (201), un capot fixe (206) et un capot mobile (207) qui est mobile en translation entre une position de fermeture et une position d’ouverture dans laquelle une fenêtre s’ouvre entre une veine (202) et l’extérieur, un volet inverseur (104) mobile autour d’un axe de rotation (50) sur le capot mobile (207) entre une position escamotée et une position déployée, et un système de déploiement (150) comportant une première bielle (152) mobile en rotation sur la structure fixe (201), une deuxième bielle (154) mobile en rotation sur le capot mobile (207) et fixée mobile en rotation à la première bielle (152), une troisième bielle (160) mobile en rotation sur le capot mobile (207), une quatrième bielle (164) fixée mobile en rotation à la deuxième bielle (154) et à la troisième bielle (160), et une cinquième bielle (170) fixée mobile à la troisième bielle (160) et au volet inverseur (104). La présence de la troisième bielle permet un décalage entre la translation du capot mobile et la rotation du volet inverseur. Fig. 4The invention relates to a nacelle (102) comprising a fixed structure (201), a fixed cowl (206) and a movable cowl (207) which is movable in translation between a closed position and an open position in which a window opens between a duct (202) and the outside, a reversing flap (104) movable about an axis of rotation (50) on the cover movable (207) between a retracted position and a deployed position, and a deployment system (150) comprising a first link (152) movable in rotation on the fixed structure (201), a second link (154) movable in rotation on the movable cover (207) and fixed movably in rotation to the first link (152), a third link (160) movable in rotation on the movable cover (207), a fourth link (164) fixed movably in rotation to the second link ( 154) and to the third connecting rod (160), and a fifth connecting rod (170) fixed mobi le to the third connecting rod (160) and to the reversing flap (104). The presence of the third connecting rod allows an offset between the translation of the movable cowl and the rotation of the reversing flap. Fig. 4
