Abstract: A large heavy lift airship of lenticular shape divided into upper and lower convex shaped halves and configured with horizontal configurations in each half made up of four quadrants of inter-connected buoyant gas cells in which the interconnections consist of inline heat exchangers and blowers that control temperatures and buoyancy, giving a high degree of buoyancy, attitude and trim control. The flat lenticular design and large lifting capacity allows for a very large passenger or cargo deck positioned in the center of the airship, dividing it into its upper and lower convex shaped halves.

Abstract: A large heavy lift airship of lenticular shape is described making use of multiple temperature controlled buoyant cells for smooth control of buoyancy and trim.
