Abstract
An airship for lifting and transporting loads, particularly heavy loads. The lifting ability of the airship is given by lighter than air gas contained in bags located between two parallel horizontal platforms constructed in lightweight geodesic fashion, the platform and bag assembly being raised and lowered by means of respectively injecting and exhausting the gas into and from the bags, the whole, together with the lifted object, being moved and steered through the atmosphere by the combined means of conventional powered propeller units and a curtain circumferential to and rotated about the platforms thus using the Magnus Effect.

12. An airship for lifting, transporting and depositing loads comprising:
-
a lower substantially horizontal platform of two-dimensional geodesic structure having parallel upper and lower planar surfaces and a periphery;
an upper substantially horizontal platform of two-dimensional geodesic structure, substantially similar in size and shape to the lower horizontal platform, and having parallel upper and lower planar surfaces and a periphery;
a plurality of vertical struts attached to and within the geodesic structure of the lower platform and of the upper platform;
a plurality of cables for connecting the upper and lower platforms and maintaining the platforms parallel and the platforms'"'"' peripheries parallel, the cables each having two ends, one end attached to one of the struts attached within the lower platform and the other end to one of the struts attached within the upper platform, said cables and struts being of such a number and so respectively attached and disposed as to form a plurality of hexagonal horizontal cross-section enclosures each bounded by six of the cables;
located between the platforms, a plurality of gasbags, each of hexagon horizontal cross-section, each having a horizontal top and bottom both having parallel planar upper and lower exterior and interior surfaces, and each gasbag also having vertical sides having exterior and interior surfaces, a means of inflation by a gas of lower-than-air density for the gasbags to lift the connected platforms, and a means of deflation for the gasbags correspondingly to lower the connected platforms, the interior surfaces of the sides and the lower interior surfaces of the gasbags having a reflexive index near 1.0 and the tops being made of material resistant to normal operating temperatures, but of such a melting point that a fire in a bag would cause the top of said bag rapidly to melt, and each gasbag when inflated having a height equal to the maximum distance between the upper and lower platforms, the plurality of gasbags being so disposed and each gasbag of such a size that each, when inflated, fully occupies one of the hexagonal enclosures formed by six of the cables and is supported and located by the cables, and that when all gasbags are inflated the upper surfaces thereof are in contact with and occupy substantially all of the lower surface of the upper platform;
a plurality of powered propeller units, each mounted on one of the platforms and capable of being rotated under control so as to deliver propulsion in any substantially horizontal direction, for propelling and steering the lifted platforms;
