Abstract:
In one example, a free-flying tethered airship system includes an upper airship adapted to tailor its lift and drag, a lower airship adapted to tailor its lift and drag, and a tether connecting the upper airship to the lower airship such that the upper airship is at least one kilometer above the lower airship. The upper airship is configured to be equiliberally buoyant, while carrying the tether, in a first altitude range. The lower airship is configured to be equiliberally buoyant in a second altitude range, the first altitude range being higher than the second altitude range. A method for stationkeeping of a free-flying tethered airship system is also provided.
Abstract:
A system and method for internally supporting a flexible envelope such as an airship is described, comprising a truss structure and supporting struts attached to a central support member. The internal structure may be foldable so as to allow the envelope to be collapsed when not in use.

Abstract:
An aerodynamic fairing system for an airship having a substantially spherical balloon portion includes an inflatable fairing that is attachable to the balloon portion, and a fairing actuation mechanism that selectively inflates and deploys the fairing after lift-off, and deflates and retracts the fairing before landing. The actuation mechanism includes an inflation/deflation mechanism and a deployment/retraction mechanism that cooperate to deploy and inflate the fairing, and to deflate and retract the fairing. The fairing includes a substantially conical, inflatable tail section tapering from a wide forward end to a narrow aft end, and a collapsible annular collar connecting the forward end of the tail section to the balloon portion. The inflation/deflation mechanism includes a fan system in the tail section, and the deployment/retraction mechanism includes a plurality of cables attached between the tail section and a plurality of winches mounted on the balloon portion.
Abstract:
Method for transporting containers in which a group of containers includes a subset M assigned to the transportation of goods and a subset V assigned to the transportation of a dismountable vehicle, wherein before it is shipped, the disassembled vehicle is loaded into the containers of subset V, between the originating handling facility and an intermediate handling facility, the group of containers which includes sub-groups M and V is transported by a first means of transportation, between the intermediate handling facility and the final handling facility, the container sub-group M is transported by the dismountable vehicle, and the dismountable vehicle being a modular multi-lift airship formed by modules that can be accommodated within the containers of group V.
Abstract:
The present invention provides a solar-powered transformable airship, on which solar cell panels are installed all over to maximize the amount of solar energy collected. Moreover, the airship according to the present invention has a main body of variable volume, suitable for any altitude, ranging from the ground to 30 kilometers high, providing very good economic potential.
Abstract:
An airship in the form of a self-powered, elongated dirigible which comprises at least three sections connected together by joints. The sections including a front section with propulsion devices and control surfaces, at least one intermediate section designed to carry a payload and a rear section with control surfaces. The joints allow limited articulation between sections under gust conditions and tend to return the sections to aligned condition in calm air. A cover may provide a streamline exterior shape for the airship; alternatively the sections may have rims which mate together when there is no articulation to provide a smooth exterior shape.
Abstract:
The invention relates to an airship comprising a flexible envelope having at least one adjustment region provided with two longitudinal adjustment elements mounted in opposition and mobile in relation to each other between a maximum distancing position and a minimum distancing position, the two longitudinal adjustment elements being connected to each other by a group comprising a plurality of cables crossing the inner space of the envelope, each of the cables cooperating with a plurality or tightening points provided along each longitudinal element. The cables are connected to at least one tightening module that can exert a tightening or loosening action on the cables and thereby bring the longitudinal adjustment elements closer together or move them further away.
Abstract:
A self-righting aerostat (10) is described comprising at least one blimp-shaped body (12), supported by gas and in which a bow and a stern are defined, a plurality of tailplanes (13) having a stabilizing function, a self-righting system provided with a ballast, consisting of liquid, able to be moved through a pump (22) from the bow to the stern of the blimp-shaped body (12) and vice-versa, a system for controlling the trim based upon the actuation of mobile parts (27) of the tailplanes (13) and on propellers driven by motors (28; 29), and a takeoff and recovery system (34) comprising a winch device (35) on which a cable is wound (19) to anchor the aerostat to the ground (10). The self-righting aerostat (10) also comprises, inside the blimp-shaped body (12), at least one connection cable (25) between the stern and the bow of the blimp-shaped body (12) itself, in order to improve the rigidity of shape of the aerostat (10) when it is pulled about in strong winds, which tend to stretch the relative blimp-shaped body (12).
