The invention concerns a free lighter-than-air aerostat comprising a structure (1, 3, 4, 5) symmetrical relative to a main axis (2), at least one main sealed pressurized chamber (16), one or several particle emitting thrusters (8), adapted to drive the aerostat in rotation in one direction about the main axis (2), one or several moving flaps (9) adapted to be set either in an active state wherein they brake the aerostat rotation, or in an inoperative state wherein they offer no substantial resistance to the aerostat rotation, and on-board control means (...
1. A free aerostat, comprising:a strengthening structure (1, 3, 4, 5), which defines a shape which is symmetrical relative to a main axis (2); at least one main chamber (16) closed in a sealed manner, which is integral with the said structure, and is pressurised by a gas which is lighter than air, such as to permit flight of the aerostat; means (8, 9) for driving the aerostat comprising: one or a plurality of particle-emission propulsion units (8) supported by the said structure, which are regularly distributed around the main axis (2), and are designed ...
