  • Patent number: 10894591
    Abstract: A hybrid VTOL vehicle having an envelope configured to provide hydrostatic buoyancy, a fuselage attached to the envelope and having at least one pair of wings extending from opposing sides thereof to produce dynamic lift through movement, and a thrust generation device on each wing and configured to rotate with each wing about an axis that is lateral to a longitudinal axis of the envelope to provide vertical takeoff or landing capabilities. Ideally, the envelope provides negative hydrostatic lift to enhance low-speed and on-the-ground stability. A vehicle comprising a first lift device capable of providing hydrostatic lift; a second lift device capable of providing dynamic lift through movement; and a system structured to generate thrust coupled to the second lift device, the second lift device and the thrust generation system capable of rotating together about an axis that is lateral to a longitudinal axis of the vehicle at angles at least in the range of 90 degrees to and including 180 degrees.
