Abstract
Una paletta di turbina è progettata per evitare di dover lavorare a macchina una parte dell'ultima paletta montata in una fila per effettuarne l'adattamento. La posizione del centro di rotazione della radice è stata scelta con cura in modo che sia disposta in prossimità verticale del bordo anteriore della parte di base.
