Patent attributes
Tethered unmanned aerial vehicle (TUAV) includes at least one wing fixed to a fuselage. The wing is comprised of an airfoil shaped body capable of producing lift in response to a flow of air across a major wing surface, and can include at least one flight control surface, such as an aileron. One or more buoyancy cell is disposed within the fuselage for containing a lighter than air gas to provide positive buoyancy for the TUAV when the TUAV is disposed in air. A tether attachment structure facilitates attachment of the TUAV to a tether which is secured to an attachment point for securing the TUAV to the ground when aloft. A wind-powered generator is integrated with the TUAV and configured to generate electric power in response to the flow of air across the least one wing when the TUAV is aloft.
