U_Hub_CVJ+HS

Unicopter ~ Rotor - Hub - CVJ+HS

(Concentric Double Universal Joint & Hub Spring)

Picture of Preliminary Mockup:

Drawing:
Could look at having a drawing here like. UNICOPTER CVJ+HS WITH STATIC MAST.DC

Objective:

To provide more control authority.

To significantly reduce the cyclical Corollas effect, which is the primary reason for lead-lag hinges?

To reduce vibration

Overview of Hub Concept:

Temporary Working Notes:

Increase the diameter of the mast?
