In one aspect, a hybrid airship including an outer shell, a plurality of helium filled gas envelopes, and an all-electric propulsion system can have a high-aspect ratio wing shape. In some embodiments, the hybrid airship may be launched using buoyancy lift alone and aerodynamic lift may be provided by the all-electric propulsion system. In one aspect, a photovoltaic array and a high energy density power storage system may be combined to power the propulsion system making the propulsion system regenerative. The high-aspect ratio wing shape provides low dr...
We claim: 1. A high-aspect ratio hybrid airship, comprising: a single outer shell having a high-aspect ratio wing shape and a thick airfoil cross-section, wherein said outer shell has a constant wingspan that is at least eight times longer than the mean chord of said outer shell; a plurality of independent gas envelopes within said outer shell, wherein said gas envelopes store helium and provide buoyancy lift to said hybrid airship; wherein said gas envelopes are the only structural shell support elements contained within said outer shell; and an all-el...
