ABSTRACT:
A rigid airship has a carrier frame with trianguar cross-ribs interconnected by longitudinal beams, one connectd to each corner of the triangle. Thus, prism-type frame sections are formed which are stiffened by diagonal tensioning members (D). The prism of each frame section (A) has two lateral sides and a base side. Each of the three sides is stiffened with two diagonal tensioning members. Junctions between neighboring frame sections are formed at the triangle corners. Carrier gas cells, the skin of which forms at least part of the airship skin, are secured in the frame sections. The base of each triangle cross-rib forms the base of the frame. One or more air chambers are formed in the belly of the airship below the base of the frame.
