Abstract

Procédé pour faire varier sélectivement le jeu en bout des aubes de turbine. Il comprend (A) la détermination du moment où la turbomachine se trouve dans une première gamme de fonctionnement prédéterminé, et (B) en réponse, le refroidissement de la frette pour en provoquer la contraction thermique afin de réduire le jeu fonctionnel entre la turbine et la frette. Application aux moteurs d'avions.
