Abstract
A turbjet engine includes various elements for adjustment of play of the stator by having the stator heated or cooled by a gas. The outer housing to which the ferrule bearing the fixed vane stages is secured may be formed of two skins between which the gas is injected. The ferrule may be composed of sectors extending over one circumference fraction and fixed via their center and simply guided at their extremity; finally, it is possible to provide sealing devices between the outer housing and the support bearing surfaces of the ribs of the ferrule elements. The volume between the ferrule and the housing is then sectioned and is able to receive separate gas feedings for play adjustment.
