Abstract

L'invention concerne une attache moteur (154) pour un moteur (102) qui comporte une poutre (302) destinée à être fixée à un mât réacteur et à laquelle est fixée de part et d'autre d'un plan médian, une bielle (304a-b), où chaque bielle (304a-b ) est fixée de manière articulée par une de ses extrémités à la poutre (302) et est destinée à être fixée de manière articulée par l'autre de ses extrémités au moteur (102), où chaque bielle (304a-b) et la poutre (302) définissent en combinaison un chemin primaire d'efforts entre le moteur (102) et le mât réacteur pour supporter les charges du moteur. L'attache moteur (154) est caractérisée en ce qu'elle comporte également pour chaque bielle (304a-b), un point de fixation de sécurité en attente (314a-b) activé en cas de défaillance du chemin primaire d'efforts et qui crée un chemin auxiliaire d'efforts entre le moteur et le mât réacteur, et en ce que les deux points de fixation de sécurité en attente (314a-b) sont disposés de part et d'autre du plan médian (XZ). Une telle attache moteur permet ainsi un déport latéral des points de fixation de sécurité en attente, facilitant ainsi leur accès par un technicien.The invention relates to an engine attachment (154) for an engine (102) which comprises a beam (302) intended to be fixed to an engine mast and to which is attached on either side of a median plane, a connecting rod (304a-b), where each connecting rod (304a-b) is hingedly attached at one end to the beam (302) and is intended to be hingedly attached at the other end to the engine (102 ), where each connecting rod (304a-b) and the beam (302) define in combination a primary path of forces between the engine (102) and the engine mast to support the loads of the engine. The engine attachment (154) is characterized in that it also comprises for each connecting rod (304a-b), a standby safety attachment point (314a-b) activated in the event of failure of the primary force path and which creates an auxiliary stress path between the engine and the engine mast, and in that the two standby safety fixing points (314a-b) are arranged on either side of the median plane (XZ). Such an engine attachment thus allows lateral displacement of the standby safety attachment points, thus facilitating their access by a technician.
