Patent number: 11964755Abstract: 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.Type: GrantFiled: May 11, 2020Date of Patent: April 23, 2024Assignee: Overair, Inc.Inventors: William Martin Waide, Abraham Karem

Patent number: 11738862Abstract: In one aspect, described herein is an aircraft capable of carrying at least 400 pounds of payload. An embodiment has four rotors systems, each of the rotor systems being independently driven by an electric motor or other torque-producing source. Each of the rotor systems provide sufficient thrust such that the aircraft is capable of controlled vertical takeoff and landing, even if one of the variable pitch rotor systems is inoperable. An electronic control system is configured to control the rotational speed and pitch of at least one of the rotor systems.Type: GrantFiled: November 24, 2020Date of Patent: August 29, 2023Assignee: Overair, Inc.Inventors: Abraham Karem, Ryan Doss, William Martin Waide, Benjamin Tigner

Each of the rotor systems provide sufficient thrust such that the aircraft is capable of controlled vertical takeoff and landing, even if one of the variable pitch rotor is inoperable. An electronic control system is configured to control the rotational speed and pitch of at least one of the rotor systems in each of the first and second rotor pairs. The rotors may be arranged in coaxial stacks or maybe otherwise configured.Type: GrantFiled: September 6, 2022Date of Patent: March 21, 2023Assignee: Overair, Inc.Inventors: Abraham Karem, Ryan Doss, William Martin Waide, Benjamin Tigner

Patent number: 10974826Abstract: 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.Type: GrantFiled: March 13, 2019Date of Patent: April 13, 2021Assignee: Overair, Inc.Inventors: Abe Karem, William Martin Waide
