Abstract
Si descrive un perfezionato complesso di palette di rotore e di disco palettato. Nella realizzazione preferita, la paletta contiene una coda di rondine curva e ritorta disposta generalmente parallela ad un perimetro esterno inclinato di disco di rotore che consente alla coda di rondine di accogliere sollecitazione centrifuga della paletta mediante cave complementari a coda di rondine per ottenere migliori limiti di vita di fatica a ciclo leggero e di fatica a ciclo pesante e una paletta relativamente rigida per mantenere un margine di 2/REV. In una realizzazione esemplificativa, la coda di rondine comprende una sezione di un'elica e la coda di rondine è autoritenente nella cava a coda di rondine conto componenti assiali di sollecitazione centrifuga.
