Abstract

TURBOREACTEUR DOUBLE FLUX COMPORTANT UNE PORTE DE BLOCAGE MISE EN MOUVEMENT PAR UNE BIELLE TRAVERSANT UNE VEINE SECONDAIRE L’invention concerne un turboréacteur double flux (100) comportant un capot moteur (103), une nacelle (106) délimitant avec le capot moteur (103), une veine secondaire (110), où la nacelle (106) comporte un capot mobile (114) mobile en translation entre une position avancée et une position reculée, une porte de blocage (116) mobile en rotation sur le capot mobile (114) entre une position escamotée et une position déployée, pour chaque porte de blocage (116), une bielle (118) arrangée pour déplacer la porte de blocage (116) de la position escamotée à la position déployée lorsque le capot mobile (114) passe de la position avancée à la position reculée, où la bielle (118) présente une première extrémité qui est articulée à la porte de blocage (116), et pour chaque bielle (118), une articulation (150) comportant un sabot (152) fixé à l’intérieur du capot moteur (103) et un levier (154) monté articulé par une première extrémité à une deuxième extrémité de la bielle (118) et par une deuxième extrémité au sabot (152), et où le capot moteur (103) présente une ouverture (156) pour le passage de la bielle (118) et du levier (154). Ainsi, en position escamotée, l’articulation ne fait plus obstacle au flux secondaire, réduisant d’autant les pertes aérodynamiques. Fig. 2The invention relates to a double-flow turbojet (100) comprising an engine cowling (103), a nacelle (106) delimiting with the engine cowling (103). , a secondary stream (110), where the nacelle (106) comprises a movable cowl (114) movable in translation between an advanced position and a retracted position, a locking door (116) movable in rotation on the movable cowl (114) between a retracted position and a deployed position, for each locking door (116), a connecting rod (118) arranged to move the locking door (116) from the retracted position to the deployed position when the movable cowl (114) passes from the advanced position to the retracted position, where the connecting rod (118) has a first end which is hinged to the locking door (116), and for each connecting rod (118), a hinge (150) having a shoe (152) attached inside the bonnet (103) e t a lever (154) mounted articulated by a first end to a second end of the connecting rod (118) and by a second end to the shoe (152), and where the engine cover (103) has an opening (156) for the passage of the connecting rod (118) and of the lever (154). Thus, in the retracted position, the articulation no longer obstructs the secondary flow, further reducing aerodynamic losses. Fig. 2
