Abstract
The invention seeks to provide a dirigible balloon with an internal enclosure (V2) having a flexible wall (4) contained in an outer rigid enclosure (15) which is of aerodynamic shape. The internal enclosure (V2) contains helium and is provided with means (5, 6, 7, 8) enabling its volume to be modified. Thus, depending on the volume given to the internal enclosure (V2) of the dirigible balloon, landing, take-off, and altitude variation are easy to perform. The means for modifying the volume of the internal enclosure (V2) comprise a cable (8) connected to the internal enclosure (V2) by means of a set of pulleys (5, 6), and a winch (7) for reducing the length of the cable (8).
Claims17
A variable-lift device comprising:
- a structure;
- and
- an internal enclosure having a flexible wall and containing a gas that is lighter than air carrying said structure,
- the internal enclosure being provided near its bottom with a first plurality of beams, each one of the first plurality of beams being provided with a first set of pulleys, and near its top with a second plurality of beams, each one of the second plurality of beams being provided with a second set of pulleys, so as to co-operate with a cable connected to a winch to constitute a block-and-tackle.
The device according to claim 7, characterized in that the ballast tank comprises two symmetrical tanks.
