Abstract: An airship (1) comprising a flexible envelope (2), a wall (3) located inside the envelope, and a pumping device. The wall (3) extends longitudinally between the nose and the tail, thus separating the inside space of the envelope into a first space (E1) and a second space (E2), said second space being located on the periphery of the envelope between a first point (P1) and a second point (P2). The pumping device is adapted to inflate the second space so that the envelope assumes a second shape, and to deflate the second space so that the envelope assumes a first shape which is different from the second shape.

Abstract: The invention relates to an airship including a flexible envelope having no rigid inner structure containing a gas that is lighter than air, and a gondola. The balloon also includes three legs for setting the balloon on the surface and a landing structure. The landing structure is located on the outside of the envelope, and provides a connection between the legs, the gondola and the envelope while surrounding the envelope.
