LTA aircraft with propulsive compressed gas stored in the tubing of the frame.

"Elongated buoyant vessel, constructed of metal sheets, in separate compartments: motive power, compressed gas, which also is used as ballast." (Aeronautical Journal, Vol. 1, No. 1, January 1897, p. 14.)

The gas, "ammonia gas or carbonic dioxide or any other similar gas having great expansive powers," is stored in thin metal tubes which form part of the framework. This gas is released from a nozzle to move the propeller directly.

The buoyant vessel (containing hydrogen gas or similar) is divided into compartments.
