    Abstract: A buoyant aerial vehicle includes a buoyant vehicle body in which gas having a specific gravity smaller than air is hermetically filled, a vertical propulsion propeller which provides vertical propulsive force, and a horizontal propulsion propeller which provides horizontal propulsive force The buoyant vehicle body is configured with flotation chambers and connecting portions. The flotation chambers are arranged at positions point-symmetric with respect to a center of the buoyant vehicle body. Central portions of the flotation chambers are bulged in a side view and the connecting portions connect the flotation chambers. The connecting portions are formed in a flat shape thinner than the central portions of the flotation chambers such that wind passages along which the air flows are formed on the connecting portions, and the wind passages are oriented in at least two directions in the plan view.

    Abstract: The purpose of this invention, which is referred to as a vacuustat, is to generate buoyancy in the atmosphere by means of an evacuated or partially evacuated container, rather than by using a lighter-than-air lifting gas such as hydrogen or helium. This particular vacuustat design comprises a flexible airtight membrane supported by a fractal tensegrity internal structure consisting of a relatively small mass of compressive members forced into higher-order buckling modes through use of tension members. The advantages of such a design over conventional aerostats include superior buoyancy control for ascent and descent, greatly increased flight endurance, and cost-effectiveness in operation. This particular vacuustat design has a much greater lifting efficiency than previous designs, and should also be easier and more cost-effective to manufacture.

    Abstract: Aspects of the disclosure relate to filling and lifting high altitude balloons. For instance, one example system for lifting and filling a balloon having a balloon envelope includes an apparatus for use with the balloon envelope. The apparatus includes a load line, a fill tube having a hollow portion nested within the load line and a termination member attached to the fill tube and load line. The load line is configured to lift the balloon envelope during inflation. The fill tube extends through the load line and is configured to allow lift gas to pass through the hollow portion. The termination member is configured to mate with an opening in the balloon envelope so that lift gas can pass through the hollow portion of the fill tube and into the opening in the balloon envelope.
