Abstract
L'invention concerne un dispositif de pilotage des jeux entre les sommets d'aubes mobiles (20) et une enveloppe annulaire (18) portant sur sa surface interne une couche annulaire de matière abradable (30) au contact de laquelle les sommets d'aubes (20) sont destinés à venir frotter, comprenant des moyens de refroidissement (36) de l'enveloppe annulaire (18) par impact d'air. Le dispositif comprend des moyens de détermination de l'épaisseur usée de la couche d'abradable au contact des sommets d'aubes, ces moyens étant reliés à des moyens de calcul et de commande (40) d'un débit d'air d'alimentation des moyens de refroidissement (36) en fonction de plusieurs paramètres dont l'un au moins concerne l'information fournie par les moyens de détermination de l'épaisseur usée de la couche d'abradable.
