Abstract

processo de controle de folga no topo de pás de rotor de turbina processo de controle de uma folga entre, por um lado, topos de pás de um rotor de turbina de um motor de avião com turbina a gás e, por outro lado, um anel de turbina de um cáter que circula as pás, o processo consistindo em comandar uma vazão e/ou uma temperatura de ar dirigido para o cáter em função notadamente de uma estimativa (j) da dita folga, caracterizado pelo fato de que a dita estimativa (j) da dita folga é determinada, por ocasião da partida do motor de avião, em função de uma temperatura (t495(t)) medida por um sensor de temperatura que inclui um elemento sensível disposto em um espaço livre do motor de avião.
