Abstract: A rotor assembly has a composite driveshaft extending between a transmission and a yoke for providing torque from the transmission to the yoke to cause rotation of the yoke and a plurality of rotor blade assemblies attached thereto. The rotor hub also has a composite static mast coupled to the yoke and a frame. The static mast being configured to carry the lift and thrust forces from the yoke to the frame.

CPC classification number: B64C29/0033 , B60L50/61 , B60L50/90 , B60L53/12 , B60L2200/10 , B64C11/001
Abstract: Systems and methods include providing an aircraft with a flight control system, a hybrid electrical or hybrid hydraulic propulsion system, and three ducted fan configuration. Each of two ducted fore fans include a single rotor system having multiple rotor blades, and a single ducted aft fan includes dual, coaxial, counter-rotating rotor systems each having multiple rotor blades. The aircraft is a vertical takeoff and landing (VTOL) aircraft that is capable of operation in an airplane mode and a helicopter mode and designed to provide an urban air-taxi that would relieve ground traffic congestion, reduce carbon emissions, and increase productivity, thereby providing a faster, more efficient means of transportation.

IPC: B64C39/02
Abstract: An Unmanned Aerial Vehicle (UAV) has a fuselage, a rotor system, and a wing configured for selective positioning during flight of the UAV to a deployed position, a stowed position, and to positions between the deployed position and the stowed position. The UAV has a flexible wing skin at least partially carried by a leading arm and the leading arm is rotatable relative to the fuselage.
