An airship (1) comprising a flexible envelope (2) , a wall (3) located inside the envelope , and a pumping means. The wall (3) extends longitudinally between the nose and the tail , separating the space inside the envelope into a first space (E1) and a second space (E2) , said second space being located at the periphery of the envelope between a first point (P1) and a second point (P2). The pumping means is capable of inflating the second space in order for the envelope to assume a second shape , and of deflating the second space in order for the envelope to assume a first shape different from the second shape. |
