ABSTRACT:
An airship has a gas-containing annulus contained by the circular base portion of framework the central portion of which extends above the annulus. The capacity of the annulus in accordance with one embodiment is such as to render buoyant a weight equal at least to the major portion of the light ship weight of the airship and in another embodiment, the annulus capacity is such as to render the airship buoyant with a maximum load. The central portion of the framework supports the load lifting propulsion system while the forward propulsion and the guidance systems ride on and are supported by tracks carried by the framework adjacent but above the annulus to travel 90.degree. in either direction from a predetermined straight-ahead position.
