Abstract:
1. An arrangement of bearing supports for a rotating shaft in an aircraft engine, said rotating shaft having a front portion carrying an equipment and extending in a rear direction from said front portion, said rotating shaft being mounted successively, in said rear direction from said front portion, on a front bearing linked to an engine stator structure by a first of said bearing supports and on a rear bearing linked to said engine stator structure by a second of said bearing supports, wherein the second bearing support comprises N>1 elastic elements which act substantially in parallel to simultaneously form a connection of said rear bearing to said engine stator structure, N−1 of said N elastic elements forming said connection through fusible components, wherein said second bearing support having N>1 elements further comprises radial end-stop components to restrict the radial displacement of the rotating shaft when the fusible components are broken, and wherein said second bearing support having N>1 elements further comprises damping components associated with said radial end-stop components.
