TURBOSHAFT ENGINE ATTACHED TO A PYLON OF THE FUSELAGE OF AN AIRCRAFT BY A FAILSAFE SUSPENSION SYSTEM

摘要

The invention relates to a suspension system including a front suspension plane located at an intermediate turboshaft engine casing and connecting same to the pylon, a rear suspension plane located at the exhaust casing of the turboshaft engine and connecting same to the pylon, and a failsafe intermediate suspension plane located between the front and rear planes and comprising at least one connecting rod (10) for connecting the turboshaft engine having a structural outer casing to the pylon, said connecting rod being mounted on the turboshaft engine with a predetermined clearance that renders the connecting rod inoperable while the suspension system of the rear plane is operating. The connecting rod (10) of the intermediate suspension plane is advantageously arranged between the outer casing and the pylon, and an element (18) made of a flexible material is combined with said connecting rod (10) so as to create said predetermined clearance by means of the elastically deformable nature thereof.
