<p>The invention discloses a device for providing greater stability to the movement of closed meteorological balloons made of dilatable material. It concerns a device to increase both the vortex of the balloon boundary layer and its aerodynamic profile. It consists, besides the main balloon (1) whose stability is to be improved, of a second balloon (5) also closed and made of a dilatable material which is fixed semirigidly on the main balloon upper pole, the two balloons increasing in volume in the same proportion. The balloons are mutually fixed by an anchoring piece (3) which ensures the linking rigidity by using the resilient tension of the main balloon envelope.</p> |
