The elements of a casing portion are formed of consecutive shells (12, 13, 14) in line with grooves (19, 20) designed to house roots (23) of guide vane stages (21, 22) which are fixed in place by springs (26) and pins (29) for stopping rotation. The elements (12, 13 and 14) are arranged in a complete circle, and the assembly is made by axially separating them to insert the elements of the guide vane stages (21, 22) between these elements by a radial movement.
Les éléments d'une portion de carter se composent de viroles consécutives (12, 13, 14) se joignant à des rainures (19, 20) de réception de pieds (23) d'étages d'aubes de redresseurs (21, 22), qui sont calés par des ressorts (26) et des pions d'arrêt en rotation (29). Les éléments (12, 13 et 14) sont en cercle complet, et le montage s'effectue en les écartant axialement pour glisser les éléments des étages redresseurs (21, 22) entre eux d'un mouvement radial.
