OK, so it’s a variation of hot air balloon with steering capability. It isn’t a LSA. But, given my fascination with airships, I see Dan Nachbar’s and Mike Kuehlmuss’ Skyacht effort as a neat project. *** Named after the aviation pioneer, Alberto (Santos-Dumont) is not a pure hot air balloon as it uses aluminum tubes and a tension line to add rigidity. Twin burners create hot air as the lifting medium. Presently a gas engine drives and maneuvers Alberto, but a quieter electric motor is planned. Alberto first flew in October 2006 and has logged more than 10 hours. It can be folded something like an umbrella so the 102-foot long, 70-foot wide envelope plus its gondola fit in a 24-foot car trailer. Cost: somewhere between $100,000 and $200,000 which is tons less than the cheapest helium blimp at about $2 million. *** I thought this a light hearted topic with which to end 2006.
Personal Blimp Uses Hot Air & Electric Motor
Using no helium, Skyacht's "Personal Blimp" is "a lighter-than-air foldable airship" that can manuever in ways to make it a potential working aircraft. See it fly in a short video that demonstrates it's ability to turn tightly.
