Abstract

Perfeccionamientos en sistemas de control en mecanismos de accionamientos del plato basculantes para el control del paso de las palas del rotor, del tipo que se disponen en un helicóptero que tiene un mástil de accionamiento del rotor que, a su vez, se mueve por una transmisión y en el cual un plato oscilante de control del paso de las palas de rotor se enlaza individualmente a horquillas de paso en cada pala del rotor, por lo menos con cuatro accionadores acoplados al plato oscilante, tres de los cuales controlan normalmente la postura y posición del plato oscilante, caracterizados porque comprenden: a) Una unidad de fuerza separada por cada accionador, moviendose independientemente cada unidad de fuerza desde la transmisión; y b) medios para cambiar el control del plato oscilante desde uno de los tres accionadores a un cuarto accionador al quedar el primero desactivado.
