Abstract
Est concerné un dispositif de contrôle de jeu entre des sommets d'aubes rotatives d’une turbomachine d’aéronef et un carter (31). Un chemin de circulation d’air (35) permet de souffler de l’air sur le carter (31), afin d'en modifier une température. Sont en outre prévus des moyens de chauffage (43) agissant sur l’air en circulation pour le chauffer. Figure à publier avec l’abrégé : Figure 3.
