Abstract
An airship has a carrier frame with triangular cross-ribs arranged so that an apex faces upwardly and a base faces downwardly, whereby longitudinal beams at the corners of the triangles interconnect the cross-ribs. The carrier frame is enclosed by an envelope including at least three skin segments joined to each other along seams coinciding with the longitudinal frame beams. Each skin segment extends entirely from the bow to the stern and may include several strips. At least two steering air chambers are provided, one near the bow, the other near the stern for trimming purposes. The seams or at least one of the seams, is so constructed that it is readily openable and closable for providing access to the interior of the airship.
