Abstract
Official abstract text for this publication.
A turbomachine blade made of composite material including a fiber reinforcement obtained by three-dimensional weaving of yarns and densified by a matrix, includes a first portion constituting an airfoil and a blade root. The first portion constitutes a single part with at least one second portion constituting a blade inner platform, the blade then lacking a blade anti-tilting wall, or a blade anti-tilting wall, the blade then lacking a blade inner platform. The first portion also constitutes a single part with at least one third portion constituting a blade outer platform spoiler plate, the blade then lacking a blade outer platform wiper plate, or a blade outer platform wiper plate, the blade then lacking a blade outer platform spoiler plate.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for fabricating a turbomachine set of blades made of composite material including a fiber reinforcement densified by a matrix, the method including: fabrication by three-dimensional weaving of a first one-piece fiber blank, shaping of the first fiber blank to obtain a first one-piece fiber blade preform having: a first portion constituting a preform of an airfoil and a blade root, a second portion constituting a preform of a blade inner p…
