Abstract

La presente invención se refiere a aparato para doblar y asegurar una pala de rotor de inclinación ajustable, caracterizado porque comprende: un miembro de sujeción de pala para conectar la pala a un rotor de impulso, el cual pivota para ajustar el ángulo de inclinación de la pala; un elemento accionador giratorio localizado en el miembro de sujeción, para pivotar la pala entre las posiciones desplegada y doblada; y un elemento para asegurar la pala sobre el miembro de sujeción, conectado operativamente con el elemento accionador y movible por este para impedir un doblado inadvertido de pala cuando esta pala está en la posición desplegada y para impedir el cambio del ángulo de inclinación cuando se dobla la pala; en donde el elemento para asegurar la pala incluye un perno de seguro de pala alargado montado en el miembro de sujeción, para reciprocarse entre las posiciones asegurada y desasegurada; y un elemento de conversión de movimiento sobre el miembro de sujeción, conectado con el elemento activador giratorio y con el perno de seguro de la pala, para convertir el movimiento pivotal del elemento activador en movimiento lineal del perno de seguro de la pala.
