Abstract
The present invention relates to a platform for a fan assembly, comprising a flow passage wall extending in an axial direction having an upstream end and a downstream end, and comprising two axial stiffeners. The platform comprises radial retention means positioned at the upstream end and at the downstream end of the flow passage wall, the radial retention means being designed to each define a sliding connection with a corresponding shroud of the fan assembly and in that it comprises tangential retention means designed to define a sliding pivot connection between the platform and a disc of the fan assembly.

A platform for a bladed wheel,
- the platform comprising a flow passage wall extending in an axial direction,
- the flow passage wall having an upstream end and a downstream end and comprising two axial stiffeners,
- the platform comprising radial retention means positioned at the upstream end and at the downstream end of the flow passage wall, the radial retention means being configured to each define a sliding connection with a corresponding shroud of the bladed wheel,
- the platform comprising tangential retention means configured to define a slide connection between the platform and a disc of the bladed wheel,
- the slide connection having an axis of rotation parallel to the axial direction, and
- wherein the platform is in sliding connection along the axial direction relative to the disc of the bladed wheel.
