ABSTRACT:
A redundant front suspension system for a turboshaft engine mounted on a pylon of an aircraft comprises a primary suspension device forming the normal front suspension of the engine, and an emergency suspension device. The primary suspension device comprises a base member secured to the pylon and having a suspension shaft which co-operates with the intermediate casing of the engine, and thrust take-up rods connect the intermediate casing to the base member. The emergency suspension device comprises an additional member which is interposed between the pylon and the base member of the primary device and which has a second shaft at its forward end extending parallel to the longitudinal axis X of the engine, the second shaft being received with clearance in a bore provided in the intermediate casing and being equipped with means for enabling take-up of forces along the X, Y and Z axes in the event of failure of an element of the primary suspension device.
