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.

Variable speed rotor `or` Constant speed rotor with large chord & Stepniewski (concept)?

Sketch:

3-blade Rotors

4-blade Rotors

Blades' radius and chord are larger than shown.

Root chords of blades are less than shown.

For a comparative evaluation of 3 versus 4 blades per rotor see; DESIGN: UniCopter ~ Rotor ~ Blades per Rotor

Note that some of the linked pages are for the old lighter Unicopter and are being revised.
