SINGLE ACTUATOR BLADE FOLD LINKAGE

摘要

An actuation assembly configured for use on a rotor blade having a first section and a second section, the second section being configured to rotate between an aligned position and a rotated position relative to the first section. The actuation assembly includes an actuator having a movable portion. A linkage assembly, coupled to the movable portion, includes a toggle link having a first end and a second end, a first group of links coupled to the first end, and a second group of links coupled to the second end. The first group of links is configured to move a locking pin between a locked position in which the second section cannot rotate and an unlocked position in which the second section can rotate. The second group of links is configured to rotate the second section of the rotor blade between the aligned position and the rotated position.

主权项

1. An actuation assembly configured for use on a rotor blade having a first section and a second section, the second section being configured to rotate about a blade fold axis between an aligned position and a rotated position relative to the first section, the actuation assembly comprising:
an actuator having a movable portion configured to move in a first direction and a second, opposite direction; a linkage assembly operably coupled to the movable portion of the actuator, the linkage assembly including:
a toggle link having a first end and a second end;a first group of links coupled to the first end and which moves a locking pin between a locked position in which the second section cannot rotate and an unlocked position in which the second section can rotate; anda second group of links coupled to the second end and which rotates the second section of the rotor blade between the aligned position and the rotated position while the locking pin is in the unlocked position.
