Abstract
L'INVENTION CONCERNE UN DISPOSITIF DE MAINTIEN D'UN ETAT DE TENSION CONSTANT DANS LES ORGANES D'UNE TURBINE DE MOTEUR A TURBINE A GAZ TEL QU'UN TURBOREACTEUR. LE STATOR DE LA TURBINE COMPORTE UN ELEMENT PORTEUR 19 DONT LE MOYEU 20 PORTE DES PALIERS D'ARBRES 35, 36 ET DONT LA PERIPHERIE PORTE DES AUBES 25 FIXEES D'AUTRE PART AU CARTER 15 DE LA TURBINE. UNE CIRCULATION D'AIR REFRIGERANT PENETRANT PAR DES REGULATEURS DE DEBIT 50 BALAIE L'ELEMENT PORTEUR ET LES AUBES. UN SYSTEME ELECTRONIQUE PERCOIT LES VARIATIONS DE TEMPERATURE DE CES DERNIERS ET REGLE EN CONSEQUENCE LE DEBIT DES REGULATEURS 50 POUR MAINTENIR CES DEUX ELEMENTS EN ETAT DE TENSION PRATIQUEMENT CONSTANTE. CES ELEMENTS, N'AYANT AUCUNE CONTRAINTE A SUBIR PEUVENT AVOIR LES DIMENSIONS ET LA FORME STRICTEMENT NECESSAIRES A LEUR ROLE AERODYNAMIQUE.
