AIRSHIP DESIGN Russian patent published in 2008 - IPC B64B1/08 

FIELD: flight vehicles.

SUBSTANCE: carcass incorporates stringers and outer covering passed on between the stringers along the negative Gaussian curvature. Inside the carcass, a lower pressure is maintained relative to outside atmospheric pressure. The carcass has a disk-like shape and radial arrangement of stringers forming in pairs the upper and lower belts of the girder combined by a rod lattice. The outer belts ends are connected in pairs and combined by a circular prestressed lattice. The inner ends of the girder upper and lower belts rest against the upper and lower support rings. The carcass accommodates a capacity for a lift gas and air ballonets communicating with atmospheric air via air valves and fans. The girder belts can be combined by membranes. Solar batteries can be supported as a cantilever all along the carcass perimeter.

EFFECT: extended functionality.
