Abstract

ATTACHE MOTEUR POUR UN MOTEUR D’UN AERONEF COMPORTANT UNE BIELLE ET UN SYSTEME ANTI-BASCULEMENT DE LA BIELLE L’invention concerne une attache moteur (200) destinée à être fixée entre un mât et un moteur d’un aéronef, ladite attache moteur (200) comportant une poutre (152) destinée à être fixée au mât, une bielle (154) à deux articulations avec une première articulation disposée au niveau d’une première extrémité (154a) de la bielle (154) et assurant la fixation de la bielle (154) à la poutre (152) et avec une deuxième articulation disposée au niveau d’une deuxième extrémité (154b) de la bielle (154) et destinée à assurer la fixation de la bielle (154) au moteur, où la bielle (154) présente un premier flanc (160a) et un deuxième flanc (160b) opposé au premier flanc (160a), et un système anti-basculement (250) comportant deux palettes (252a-b) disposées de part et d’autre de la bielle (154) où chaque palette (252a-b) est fixée à la poutre (152) et présente une languette (254a-b) solidaire de la palette (252a-b), où la languette (254a) d’une palette (252a) est en regard du premier flanc (160a) et où la languette (254b) de l’autre palette (252b) est en regard du deuxième flanc (160b). Ainsi, les languettes disposées de part et d’autre de la bielle bloquent ladite bielle lorsqu’elle s’écarte d’une position normale de fonctionnement. Fig. 2The invention relates to an engine attachment (200) intended to be fixed between a mast and an engine of an aircraft, said engine attachment ( 200) comprising a beam (152) intended to be fixed to the mast, a connecting rod (154) with two articulations with a first articulation arranged at a first end (154a) of the connecting rod (154) and ensuring the fixing of the connecting rod (154) to the beam (152) and with a second articulation arranged at a second end (154b) of the connecting rod (154) and intended to ensure the attachment of the connecting rod (154) to the engine, where the connecting rod (154) has a first side (160a) and a second side (160b) opposite the first side (160a), and an anti-tilt system (250) comprising two vanes (252a-b) arranged on either side of the connecting rod (154) where each pallet (252a-b) is fixed to the beam (152) and has a tongue (254a-b) integral e of the pallet (252a-b), where the tongue (254a) of a pallet (252a) is opposite the first side (160a) and where the tongue (254b) of the other pallet (252b) is opposite of the second flank (160b). Thus, the tabs arranged on either side of the connecting rod block said connecting rod when it deviates from a normal operating position. Fig. 2
