Abstract

Un turbomotore a gas avente un rotore anulare esterno di turbina che è controruotante rispetto ad un rotore anulare interno di turbina, contiene una struttura di fissaggio per fissare palette di turbina in file circonferenziali al rotore interno. La struttura di fissaggio contiene primi e secondi elementi maschi distanziati assialmente lungo e sporgenti circonferenzialmente attorno al rotore, i primi e secondi solchi distanziati assialmente lungo e sporgenti circonferenzialmente attorno al rotore essendo definiti da flange fissate al rotore. Ciascuno elemento maschio ha una prima porzione attaccata ad un estremo di una paletta di turbina e sporgente dalla medesima in direzione radiale. Il primo elemento maschio ha una seconda porzione attaccata alla sua prima porzione ed estendentesi dalla medesima in una direzione assiale per definire il primo elemento maschio con una configurazione complessiva in sezione a gancio. Il primo solco è sagomato in sezione per ricevere in relazione accoppiata la seconda porzione del primo elemento maschio. Il secondo solco è sagomato in sezione per ricevere in relazione accoppiata nel secondo solco un elemento di bloccaggio del complesso di bloccaggio e la prima porzione del secondo elemento maschio per bloccare gli elementi maschi nei rispettivi solchi e bloccare perciò la paletta di turbina contro movimenti radiali e assiali rispetto al rotore.
