  • Folding propellers system
    Patent number: 10155585
    Abstract: Folding propeller system for safe packing and shipping, and easy deployment.
    Type: Grant
    Filed: March 13, 2014
    Date of Patent: December 18, 2018
    Assignee: AERYON LABS INC.
    Inventors: Glen Johannesson, David Kroetsch, Michael Peasgood, Stephen Marchetti
  • Hovering unmanned aerial vehicle
    Patent number: 9783294
    Abstract: In an aspect, an apparatus includes a hovering unmanned aerial vehicle (HUAV). The HUAV includes an arm assembly configured to support a propeller in such a way that propeller drag of the propeller is decoupled from yaw torque requirements associated with the hovering unmanned aerial vehicle. In another aspect, an apparatus includes an HUAV that has an arm assembly that is field-foldable relative to the HUAV between a flight-ready state and a folded state. In another aspect, an apparatus includes an HUAV having an arm assembly that is keyed in such a way as to facilitate field-assembly relative to the HUAV.

  • Hovering aerial vehicle with removable rotor arm assemblies
    Patent number: 8322648
    Abstract: The invention provides a hovering aerial vehicle with removable rotor arms and protective shrouds. Removing the shrouds reduces the weight of the vehicle and increases flight time. Removing the rotor arms makes the vehicle easier to transport. Removable rotor arms also simplify field repair or replacement of damaged parts.
