Abstract
Official abstract text for this publication.
A composite material turbine nozzle blade including an airfoil adapted to have a cooling fluid flow through it and extending between a shroud and a root is provided. The shroud is shaped to be attached to one or more turbine casings of a turbomachine and the root is shaped to provide a junction with a turbine internal casing. The root is produced with a loosened texture and includes an external upstream side loosened texture lug and an external downstream side loosened texture lug, the ends of the two external side lugs extending axially relative to the rotation axis of the turbomachine to form a device for supporting and centering the internal casing.
First claim
Opening claim text (preview).
The invention claimed is: 1. An assembly comprising: a turbine nozzle including an assembly of composite material blades and a metallic turbine internal casing, said blades including an airfoil extending between a shroud at an upper radial end thereof and a root at a lower radial end thereof, wherein an upstream end of the shroud and a downstream end of the shroud present an internal upper upstream lug and an external upper upstream lug at the upstream end of the shroud, and an…
