UniCopter ~ Rotor
Overview:
The three blades per rotor or four blades per rotor, the two hubs and the static masts are rigidly mounted to each other. The pre-cone angle is 3 degrees, no flapping hinges, and no lead-lag hinges. The only movable components are those related to feathering. The direction of rotation is outside moving forward.
The
NACA 00xx blade is currently being developed to try to achieve Active Blade Twist w/ Independent Root & Tip Control
