Patent ID: 7500638

Claim:
A rigid lenticular shaped airship comprising: a. a first ( 45 ) and second ( 47 ) circular horizontal plane dividing the rigid lenticular shaped airship into an upper convex shaped half ( 44 ) and a lower convex shaped half; b. a first upper series of buoyant gas cells ( 42 ) in a horizontal configuration making up one upper quadrant of said upper convex shaped half ( 44 ) of said airship; c. additional second, third, and fourth series of upper buoyant gas cells in the three remaining upper quadrants of said upper convex shaped half ( 44 ); d. wherein said series of upper buoyant gas cells in each upper quadrant of said upper convex shaped half ( 44 ) of said airship are connected and in buoyant gas communication with matched upper cells in the adjoining upper quadrants, thereby being connected in upper groups of four, all in the upper convex shaped half ( 44 ) of said airship; e. and wherein the buoyant gas communication between each of the four upper buoyant gas cells of each of the upper groups of four is made by a self-contained heat exchanger and blower that provides temperature and buoyancy adjustment to each of the upper groups of four upper buoyant gas cells of said upper convex shaped half ( 44 ) of said airship f. a first lower series of lower buoyant gas cells in a horizontal configuration making up one lower quadrant of said lower convex shaped half of said airship; g. additional second, third, and fourth series of lower buoyant gas cells in the three remaining lower quadrants of said lower convex shaped half of said airship; h. wherein said series of lower buoyant gas cells in each quadrant of said lower convex shaped half of said airship are connected and in buoyant gas communication with matched cells in the adjoining lower quadrants, thereby connected in lower groups of four, all in the lower convex shaped half of said airship; i. and wherein the buoyant gas communication between each of the four lower buoyant gas cells of each of the lower groups of four is made by a self-contained heat exchanger and blower that provides temperature and buoyancy adjustment to each of the lower groups of four lower buoyant gas cells of said lower convex shaped half of said airship.
