An airship comprises two substantially parallel, spaced apart and semirigid hulls (1, 2) adapted to contain a lifting gas, a gondola (3) is connected to the hulls (1, 2), and a drive means is provided to impart vertical lift to the airship. A drive means adapted to impart horizontal motion to the airship may also be provided. Each hull (1, 2) includes a framework comprising two semirigid circumferential bands which are interconnected by a plurality of longitudinal strips and a plurality of radially extending spokes. Support means (22, 23, 24) interconnect the circumferential bands of each hull (1, 2) to the gondola (3). Each hull (1, 2) consists of an outer covering enclosing a number of gas containing cells. The hulls (1, 2) are longer than their width and wider than their height and in cross-sections they have a shape approximate to that of an aerofoil. Ventrally as compared to dorsally the hulls (1, 2) are substantially flatter. Vertical fins (8), tail planes (6), forward stabilizers (7) are provided to assist in the overall manoeuvrability and stability of the airship. |
