Abstract
Système réduisant au maximum le jeu rotor/virole aussi bien en régime permanent qu'en régime transitoire. Il comprend : a. une premiere et une seconde source d'air, la température de cette seconde source d'air étant plus élevée que celle de cette première source; b. une première et une seconde vanne d'air 55, 60, destinées à régler l'écoulement d'air venant respectivement de la première et de la seconde source en arrivant dans un collecteur; c. un dispositif qui alimente le support en air venant du collecteur; et d. un servodistributeur 48, sensible à la vitesse du rotor et au temps écoulé après atteinte par le rotor de vitesses prédéterminées, qui fait fonctionner la première et la seconde vanne. Application aux moteurs d'avion.
