Before the Wright Brothers powered their way across the sands of Kitty Hawk or Otto Lilienthal soared from the hills of Germany, enveloping hot air in a balloon was the only way to fly. Concepts were refined as time went by, and culminated in the grand Zeppelins of the 1930’s. However since the tragic end of the Zeppelin era, lighter than air aircraft have often been viewed as a novelty in the aviation world.
Several companies have come forward in the last decade, pitching enormous lighter than air machines for hauling large amounts of cargo at reduced cost. These behemoths rely on a mixture of natural buoyancy and lifting body designs and are intended to augment ferries and short haul commercial aviation routes.
It was this landscape where Buoyant Aero founders [Ben] and [Joe] saw an underserved that they believe they can thrive in: Transporting 300-600 lbs between warehouses or airports. They aim to increase the safety, cargo capacity, and range of traditional quadcopter concepts, and halve the operating costs of a typical Cessna 182. They hope to help people such as those rural areas of Alaska where high transportation costs double the grocery bill.
Like larger designs, Buoyant Aero’s hybrid airship relies on aerodynamic lift to supply one third the needed lift. Such an arrangement eliminates the need for ballast when empty while retaining the handling and navigation characteristics needed for autonomous flight. The smaller scale prototype’s outstanding ability to maneuver sharply and hold station with a tailwind is displayed in the video below the break.
