Abstract:
Apparatus, systems, and methods are contemplated for electric powered vertical takeoff and landing (eVTOL) aircraft. Such are craft are engineered to carry safely carry at least 500 pounds (approx. 227 kg) using a few (e.g., 2-4) rotors, generally variable speed rigid (non-articulated) rotors. It is contemplated that one or more rotors generate a significant amount of lift (e.g., 70%) during rotorborne flight (e.g., vertical takeoff, hover, etc), and tilt to provide forward propulsion during wingborne flight. The rotors preferably employ individual blade control, and are battery powered. The vehicle preferably flies in an autopilot or pilotless mode and has a relatively small (e.g., less than 45′ diameter) footprint.

Claim (Index 25):
The aircraft of  claim 1 , wherein the first primary rotor has a rotor hub and at least two blades radially coupled to the hub, each blade having a root proximal the hub and a tip distal to the hub, wherein each blade weight in lbs. does not exceed the product of 0.004 times the diameter of the rotor in feet cubed.
