  • Unmanned flying wing aircraft having foldable and stackable wings
    Patent number: 11613343
    Abstract: A foldable aerial vehicle may take the form of a flying wing. The flying wing includes port and starboard wings having port and starboard root and tip portions. The port and starboard root and tip portions are hinged one to another so that the span axes of all of the root and tip portions are parallel in the stowed condition and so that the tip portions are separated by the root portions in the deployed condition to define the flying wing. The wings are not symmetrical about the longitudinal axis of the vehicle, with the span axes of the root and tip portions being stepped from one wing tip to the other. Folding winglets are disposed on opposing wing tips, with the higher winglet extending in an upward direction and the lower winglet extending in the downward direction.
