Abstract:
1. A pressure-stabilized, non-rigid airship, lacking an internal rigid framework, comprising: a pressurized gas impervious envelope having an inner surface and an outer surface, said inner surface defined by a width orientation and a length orientation; at least one partition having a partition inner edge and a semi-circular partition outer edge, wherein said semi-circular partition outer edge is attached about a semi-circular portion of said inner surface of said pressurized gas impervious envelope, such that said partition spans a partial amount of said width orientation of said pressurized gas impervious envelope; and at least two diaphragms having opposed diaphragm outer edges connected to one another by opposed diaphragm inner edges, wherein said diaphragm outer edges are attached anywhere along said inner surface of said length orientation of said pressurized gas impervious envelope, and said diaphragm inner edges are attached to said partition inner edges, so as to form a plurality of lifting gas cells and an undivided air cell that spans the length orientation of said pressurized gas impervious envelope, and wherein said diaphragms are formed to traverse the distance defined by upper and lower extremities of said pressurized gas impervious envelope.
