The invention concerns a steered aerostatic balloon and in particular the creation of balloons of large volumes, which are free (airships, space balloons) or captive (material loading or unloading balloons). This balloon has an outer envelope (1) containing air, an interpolar connector (11) connecting the lower pole (2) and the upper pole (3) of this envelope, a grid of longitudinal reinforcements (8) connected to the poles (2) and (3), a grid of circumferential reinforcements (8) connected to the poles (2) and (3), a grid of circumferential reinforcements (7), at least one inside envelope (12) within the first envelope and containing helium, this latter envelope during inflation coming to rest against the outer envelope and being provided with poles fixed on the interpolar connector (11), and lastly air intake means and air evacuation means to and from the outer envelope. |
