Aeroscraft takes to the air


One of my favorite airships in the ongoing hope to develop cargo aircraft, the Aeroscraft, is moving further along. It did a tethered flight, and will soon be doing an untethered one.

“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 hydrogen power.”
