Airship

摘要

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.

1. An airship, comprising:
a flexible envelope without a rigid internal structure imposing a shape on the envelope, said envelope delimiting an inside space intended to be at least partially filled with a lighter-than-air first gas, extending along a longitudinal axis between a nose located at the front of the airship and a tail located at the back of the airship, and comprising an upper portion located at the top and a lower portion located at the bottom, said lower portion being opposite the upper portion, a wall located inside the envelope, said wall being flexible, being gas-tight, extending longitudinally between the nose and the tail thus separating the inside space of the envelope into a first space intended to be filled with said first gas and a second space intended to be filled with a second gas, said second space being located on the periphery of the envelope between a first point and a second point of a perimeter within a plane perpendicular to the longitudinal axis, and a pumping device adapted for inflating the second space to a control pressure greater than a pressure of the first space so that the envelope assumes a second shape by bringing the first and second points closer together, and for deflating the second space to a control pressure substantially equal to the pressure of the first space so that the envelope assumes a first shape that is different from the second shape, and wherein: the second space is delimited between a portion of the envelope and the wall, and the wall has a curvilinear length less than or equal to a curvilinear length of the portion of the envelope, in the plane perpendicular to the longitudinal axis.
