Abstract: The design and refinement of a tethered hovering platform into a feasible working system is presented. To determine a starting point for the design, a detailed historical search was conducted to find the history and the current state of such technology. Real world current needs are analyzed to produce a mission specification and to drive the preliminary vehicle design. Analysis of environmental conditions and decisions about an initial payload package are made in conjunction with motor and propeller sizing. Initial concept testing to discover feasibility and operational issues was performed; from this, instability issues were discovered. Analyzing these instability issues using known rotorcraft and momentum effects, in conjunction with flight testing, yields possible solutions to the problem. The use of constrained layer dampers as a means of passive stabilization is addressed and suggested as the preferred solution. Testing of passive constrained layer damping verifies the stability of the solution. The system components and manufacturing cost is presented in comparison to current systems using active stabilization

Abstract: An aerial robot is disclosed. The aerial robot may include at least one pair of counter-rotating blades or propellers, which may be contained within a circumferential shroud or a duct. In one embodiment, the aerial robot may have the ability to hover and move indefinitely. Electric power to the robot may be provided by a tether or an on-board power supply. In tethered embodiments, a solid-state, electronic voltage transformer may be used to reduce a high voltage, low current source to lower voltage, higher current source. In one embodiment, secure data communication between a ground unit and the aerial robot is facilitated by impressing high bandwidth serial data onto the high voltage tether wires or a thin optical fiber which is co-aligned with the tether wires. In one embodiment, precise navigational and position controls, even under extreme wind loads, are facilitated by an on-board GPS unit and optical digital signal processors. In one embodiment, if the tether detaches, precision free-flight is possible with on-board batteries.

Abstract: A method and an apparatus for capturing a flying object (5) are revealed. The apparatus includes a generally linear fixture (2), such as a length of rope; a means for suspending (1) the fixture (2) across the path of the flying object (5); and one or more hooks (19) on the flying object (5). The method involves suspending the fixture (2) such that its orientation includes a component normal to the flying object's line of approach; striking the fixture (2) with the flying object (5), which causes the flying object (5) to rotate and decelerate, while the fixture (2) slides along a surface of the flying object (5) into a hook (19); capturing the fixture (2) in the hook (19); and retrieving the flying object (5) from the fixture (2).

Abstract: A method and apparatus for retrieving an aircraft in a confined space involves hanging a cable, for example from a kite or mast, across the aircraft's flight path. The aircraft approaches the cable in steady forward flight, and may strike the cable at any point on the wing, fuselage, or other leading surface. The cable then slides along the airframe as the aircraft moves forward, until it is intercepted by a hook attached to the wing tip or other convenient location. The hook captures the cable, and prevents further sliding; the cable then pulls the aircraft to a stop. Compliance of the cable, optionally combined with compliance of the cable suspension, provides acceptably gradual deceleration. The aircraft is left suspended in mid-air, and is then winched or slid to the base of the cable or other convenient retrieval point. The cable suspension and other fixed objects can be kept well clear of the flight path, so that the aircraft can continue safely in the event that it misses the cable, and make another approach.
