Abstract

Ensemble dans lequel les aubes fixes sont supportées par un autre dispositif que des rotules et des moitiés appariées. Il comprend une aube fixe 20 possédant, à une extrémité un tourillon 24 d'un premier diamètre, un bandeau 18, introduit autour du tourillon pour délimiter un chemin d'écoulement 14 à travers la turbine; un bâti structural 136, distant radialement de l'extrémité du tourillon, ce bâti étant percé d'un trou 140 d'un second diamètre, de manière générale aligné avec le tourillon ; et un prolongement de tourillon 142, de manière générale cylindrique, dont le diamètre intérieur est sensiblement égal au premier diamètre et dans lequel est introduit le tourillon; ce prolongement possédant en outre un diamètre extérieur, sensiblement égal au second diamètre, et pivotant dans le trou du bâti structural, qui lui sert de palier; et un dispositif 154, 162 qui fixe ce prolongement sur le tourillon. Application aux moteurs à turbine à gaz.
