    摘要: 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.

    摘要: 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 at least four, and more preferably at least six variable speed tilt rotors. In some embodiments one or more rotors cooperate to generate at least 50% of the lift, and more preferably at least 70% of the lift, during rotorborne flight (e.g., vertical takeoff, hover, etc). At least some of the blades of each of the at least four rotors are not feathered, retracted, or folded during forward flight. At least one of the variable speed tilt rotors is engineered to be optionally powered by multiple motors, and by multiple battery packs or other independently operating electric power sources. The vehicle preferably flies in an autopilot or pilotless mode and has a relatively small (e.g., less than 45′ diameter) footprint.

    摘要: A harmonic drive has an outer gear, an elliptical follower hub, and an outer chain coupled to the follower hub, and having teeth that mate with the outer gear. Preferred embodiments further include an inner chain disposed such that the follower hub is functionally interposed between the inner and outer chains.
