Rotor blade stowing system for stowing rotor blades that conserves storage space without adding significant weight or cost to the aircraft. The system includes a rotary actuator disposed on a blade grip member. A rotor blade is pivotally connected to the blade grip member. The rotary actuator is operably coupled to a blade pivoting cam and a locking cam. The system includes a cam follower linkage which has a first end which includes a blade pivoting cam follower and a locking cam follower and a second end. The blade pivoting cam follower follows the blad...


[ We claim:] [1.] A rotor blade stowing system for stowing a rotor blade comprising:a rotary actuator for pivoting a rotor blade between folded and deployed positions, said blade being pivotally connected to a blade grip member, said rotary actuator being disposed on said blade, said rotary actuator being operably coupled to a blade pivoting cam and a locking cam, said blade pivoting cam having a shoulder portion, said locking cam having a detent;a cam follower linkage having a first end and a second end, said first end of said cam follower linkage havin...
