Abstract
Official abstract text for this publication.
A turbine nozzle comprises a plurality of composite material vanes, each vane comprising an inner platform, an outer platform with attachment tabs on the outside, and at least one airfoil extending between the inner and outer platforms and secured thereto. The attachment tabs of the vanes are engaged on a metal assembly ring supporting all of the vanes, extending continuously along the outer platforms of adjacent vanes, and forming a distinct assembly part between the vanes and a turbine casing.
First claim
Opening claim text (preview).
The invention claimed is: 1. A turbine engine stator wheel, comprising: a plurality of vanes each comprising an inner platform, an outer platform presenting attachment tabs on the outside, and at least one airfoil extending between the inner and outer platforms, the vane and the outer platform together with the attachment tab forming a single piece of ceramic matrix composite material or of organic matrix composite material; and a metal assembly ring in which the attachment tabs…
