  • Patent number: 9004397
    Abstract: An autonomous stratospheric unmanned airship with an operating altitude from 5-22 km and with a multi-month operational cycle. Spheroid rigid geodesic frame of constant volume formed by a multitude of struts, with an outer envelope enclosing the frame defining the eigenfrequency spectrum of the airship above 20 Hz, with vibrational amplitudes between 0.1 and 1 cm. Independently controllable electrical propulsion units, attached to the frame in the horizontal plane passing through the center of mass, can change the direction and value of the thrust vector. Buoyancy is controlled with a system integrated inside the geodesic frame including buoyant fluid pressurized tanks, valves for the release of the buoyant fluid through the buoyant fluid conduit into the buoyant gas cell which fills the geodesic frame. Valves at the subsystem support platform enable ambient atmosphere to fill the internal volume of the frame not occupied by the buoyant gas cell.
