Abstract

La présente invention concerne une turbine à gaz comportant un dispositif thermoélectrique capable de changer un jeu d'extrémité dans un composant de turbomachine. Dans une forme non limitative, le composant de turbomachine est un compresseur. Le dispositif thermoélectrique peut être utilisé sous différentes formes pour récolter la puissance provenant de la chaleur perdue. Le système de commande de jeu d'extrémité peut comprendre un capteur servant à déterminer le jeu entre une extrémité et une paroi du composant de turbomachine.
