초록

A variable pitch fan blade assembly includes a hub, a pitch-adjusting assembly, a fan blade, and an actuator. The pitch-adjusting assembly includes a first element rotatable on a first axis and a second element rotatable on a second axis. The first element presents an elongated pitch pin. The second element defines an elongated pitch slot receiving the pitch pin. The fan blade is coupled to one of the elements for rotation therewith. The actuator is coupled to the other of the elements for rotation therewith. When the actuator rotates the element to whic...
