Abstract

Turbomachine à jeu variable en bout de turbine pendant des conditions prédéterminées du fonctionnement. Elle comprend : a. un support de frette 37 relié à la frette 33 de telle manière qu'il provoque la dilatation et le retrait de la frette en relation avec sa variation de température. b. des moyens pour détecter une première condition indicatrice de la vitesse de la machine, et c. des moyens pour appliquer sélectivement un flux de réfrigérant à ce support de frette afin de provoquer son retrait et ainsi réduire le jeu entre la frette et le rotor. Application aux moteurs à turbine à gaz d'avions.Turbomachine with variable clearance at the end of the turbine during predetermined operating conditions. It includes: a. a hoop support 37 connected to the hoop 33 in such a way that it causes the expansion and the withdrawal of the hoop in relation to its temperature variation. b. means for detecting a first condition indicative of the speed of the machine, and c. means for selectively applying a flow of coolant to this hoop support in order to cause its withdrawal and thus reduce the play between the hoop and the rotor. Application to gas turbine engines for airplanes.
