Abstract

PROCEDE ET UNITE DE COMMANDE POUR LE PILOTAGE DU JEU D’UNE TURBINE HAUTE PRESSION POUR LA REDUCTION DE L’EFFET DE DEPASSEMENT EGT Procédé de pilotage d’un jeu entre des sommets d’aubes d’un rotor d’une turbine de moteur d’avion et un anneau de turbine, comprenant l’estimation du jeu à piloter et la commande d’une vanne délivrant un flux d’air dirigé vers l’anneau de turbine en fonction du jeu ainsi estimé, ce procédé comprenant : la détection (100) d’une phase transitoire d’accélération à partir d’au moins un paramètre représentatif du moteur ; la réception (102) d’une donnée relative à l’altitude de l’avion ; la détermination (104) de données représentatives de la température du rotor pendant la phase transitoire d’accélération et en régime stabilisé et le calcul d’un écart relatif de températures ; si la phase transitoire d’accélération est détectée et si l’écart relatif de températures est supérieur à un écart de température minimal prédéterminé, la définition d’un niveau d’ouverture et d’un temps d’ouverture de la vanne par une table de correspondance altitude/écart relatif de températures prédéfinie ; et la commande (114) de l’ouverture de la vanne pour délivrer le flux d’air à l’anneau de turbine. Figure pour l’abrégé : Fig. 3.
