The Aluminum Airship of the Future Has Finally FlownAndrew Tarantola9/13/13 1:00pmFiled to: Monster Machineszeppelinsdirigiblesaeroscraftaeros51438EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkThere was once a time when man looked to the skies and expected to see giant balloons rather than airplanes drifting above. The Hindenburg Disaster promptly put an end to those dreams. But nearly a century later, one company may have finally figured out how to build a dirigible suitable for the 21st century. Just don't call it a blimp. This fully rigid airship, dubbed the Aeroscraft, differs fundamentally from, say, the Goodyear blimp. Blimps, by definition, have no internal structure and maintain their shapes only through the pressure of the gas they contain; when the gas escapes, they deflate like the gigantic balloons they are. Rigid airships, like zeppelins before them, maintain their shape regardless of gas pressure thanks to an internal skeleton structure—the Hindenburg utilized highly flammable balsa wood, but the Aeroscraft's is made of aluminum and carbon fiber—and maintains its buoyancy with a series of gas-filled bladders. And unlike hybrid airships, the Aeroscraft doesn't require forward momentum to generate lift via a set of wings. It's all helium power.
