  • Patent number: 7887011
    Abstract: An airborne cargo-carrying apparatus includes support and lower structural frames; a retaining mechanism securing a cargo carrier to the support frame; collapsible nose and tail cones coupled to the frames; flexible side panels coupled to the cones and frames; and a cargo door mounted on the lower structural frame. The support frame includes a top panel. The cones and panels are arranged—with the cones collapsed, side panels folded, and cargo door open—to enable the support frame and the cargo carrier to be secured together with the retaining mechanism engaged. The cones, panels, and cargo door are arranged—with the cones expanded, side panels unfolded, and cargo door closed—to substantially envelop the cargo carrier secured to the support frame within an aerodynamic enclosure.

  • Patent number: 7070145
    Abstract: A disclosed flying craft includes a suspension structure having a first end and a second end, a lift unit, and a payload unit. The lift unit includes a nacelle and a tailboom, and pivotally couples to the first end of the suspension structure, and a payload unit couples to the structure's second end. Thus the tailboom can pivotally couple with respect to the payload unit, which advantageously permits the tailboom to assume an orientation desirable for a particular mode of flight. During vertical flight or hover, the tailboom can hang from the lift unit in an orientation that is substantially parallel to the suspension structure and that minimizes resistance to downwash from the lift unit. During horizontal flight, the tailboom can be orthogonal to the suspension structure, extending rearward in an orientation where it can develop pitching and yawing moments to control and stabilize horizontal flight. Advantageous variations and methods are also disclosed.

  • Patent number: 7059562
    Abstract: A disclosed vertical lift flying craft includes a lift unit that, during operation, develops a force including an upward component. A payload unit suspends from the lift unit. The payload unit suspends from the lift unit in such a way as to impart lateral stability while remaining capable of horizontal flight, without incurring the adverse effects of a downward pitching moment. In addition to a lift unit and a payload unit, the vertical lift flying craft includes a pair of bearings and a suspension structure, which cooperate to suspend the payload unit from the lift unit. Other systems and methods are also disclosed.
