AIRCRAFT TURBOMACHINE ENTRY CONE

Abstract

The present invention relates to an inlet cone (20) for an aircraft turbomachine (1), said inlet cone (20) being configured to be driven in rotation about an axis (X) and comprising a frustoconical body (22) and a tip (21) made of elastically deformable material fixed to a smaller diameter end (221) of said body (22), the body (22) having through-holes (222) distributed about the axis (X) and parts (23) made of elastically deformable material located in said through-holes (222), wherein each of the parts (23) made of elastically deformable material comprises at least one peripheral rim (230) for retaining said part (23) in the corresponding through-hole (222), said at least one peripheral rim (230) bearing against an internal surface (22a) of said body (22).
