Abstract
An inlet cone for an aircraft turbomachine, having at least one first portion made of a first material, referred to as rigid material, and at least one second portion made of a second material which has a hardness less than that of said first material and which is referred to as flexible material, these second portions being configured to deform elastically in the radial direction with respect to the axis when the cone is being driven to rotate.
Claims14
An inlet cone for an aircraft turbomachine, this inlet cone being configured so as to be driven in rotation about an axis and comprising a body of conical or elliptical shape and on which ice is capable of forming, said body having at least one first portion made of a first material referred to as rigid material, and at least one second portion made of a second material which has a hardness less than that of said first material and which is referred to as flexible material,
- wherein said first portion is monobloc and formed by a plurality of axial sections connected together by partitions extending in a longitudinal direction relative to the axis, said sections and said partitions defining between them housings, and in that said body comprises a plurality of second portions located in said housings, these second portions being configured to deform elastically in the radial direction with respect to the axis when the cone is driven in rotation.
