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.
