Abstract

Embodiments of the present disclosure provide systems and methods for a hub. The system provides a hub comprising at least two blades, a motor mechanically connected to the at least two blades to rotate the at least two blades, wherein the motor is attached to an frame; and a hub configured to transmit loads from the at least two blades to the frame, wherein each blade is coupled to an inboard elastomeric bearing attached to the hub, and wherein each blade is coupled to an outboard elastomeric bearing attached to the hub. The hub may comprise a pitch horn configured to couple one of the at least two rotor blades at an attachment to the inboard elastomeric bearing.

• B64C 27/35 - Rotors having elastomeric joints
• B64C 27/48 - Root attachment to rotor head
• B64C 27/78 - Mechanisms for controlling blade adjustment or movement relative to rotor head, e.g. lag-lead movement in association with pitch adjustment of blades of anti-torque rotor
• B64C 11/06 - Blade mountings for variable-pitch blades
