Abstract

Stator de turbine à gaz. Ce stator comprend plusieurs pales ou ailettes de guidage et des organes pour monter lesdites pales dans un passage prévu pour l'écoulement des gaz, en aval du rotor de la turbine, le bord d'attaque de ces pales étant incliné de 20 à 60 degrés par rapport à un plan radial normal à l'axe du rotor. L'inclinaison peut être choisie de façon à ce que ce bord soit sensiblement rectiligne depuis l'extrémité interne jusqu'à l'autre extrémité ou bien peut presenter un profilé sensiblement en U. Application à la réalisation de pales de stator de turbine permettant de résister aux contraintes thermiques et aux vibrations et n'affectant pas l'écoulement du gaz.
