lk banner2 Lost Knowledge: AirshipsThe weekly Lost Knowledge column explores the possible technology of the future in the forgotten ideas of the past (and those slightly off to the side). Each Tuesday, we look at retro-tech, “lost” technology, and the make-do, improvised “street tech” of village artisans and tradespeople from around the globe. “Lost Knowledge” is also the theme of the current issue of MAKE, Volume 17 (on newsstands now)

With a crew of drunken pilots, We’re the only Airship Pirates!
We’re full of hot air and we’re starting to rise
We’re the Terror of the skies, but a danger to ourselves now.

Airship Pirate, Abney Park

airship1 Lost Knowledge: Airships

Zeppelins. Airships. Dirigibles. These words have fired my imagination since I was a child and put together my first Zeppelin scale model. And as a headbanging teen, my devotion to a Led Zeppelin meant that I was always surrounded by icons of these floating horizontal skyscrapers. Every decade or so, there seems to be a resurgence of interest in airships, with new material availability, an energy crisis, or some other motivating factor. Today is no different. So here’s a sampling of some of the airships of the past, a few in the skies of the present, and some fantasies for the near-future.

So far, efforts to create a serious and sustained airship industry have fallen far short. It seems unlikely that airships will ever become common transportation, but it’d be nice to see them find some sustainable niche.

Wikipedia has a lot of great information and links related to airships. Here’s an excerpt from the main Airship page:

“The Golden Age”

The “Golden Age of Airships” began in July 1900 with the launch of the Luftschiff Zeppelin LZ1. This led to the most successful airships of all time: the Zeppelins. These were named after Count von Zeppelin who began experimenting with rigid airship designs in the 1890s leading to the badly flawed LZ1 (1900) and the more successful LZ2 (1906). At the beginning of World War I the Zeppelin airships had a framework composed of triangular lattice girders, covered with fabric and containing separate gas cells. Multi-plane, later cruciform, tail fins were used for control and stability, and two engine/crew cars hung beneath the hull driving propellers attached to the sides of the frame by means of long drive shafts. Additionally there was a passenger compartment (later a bomb bay) located halfway between the two cars. Other airship builders were also active before the war: German firm Schütte-Lanz built the SL series from 1911; another German firm Luft-Fahrzeug-Gesellschaft built the Parseval-Luftschiff (PL) series from 1909, and Italian Enrico Forlanini‘s firm had built and flown the first two Forlanini airships.

QUEST on KQED Here KQED’s Quest video documentary, Zeppelins Resurrected, about the crash of the USS Macon in the 30s and the return of airships to California:

The Hindenburg wasn’t the only air ship to end in a catastrophic crash. In 1935, the USS Macon went down in 1000 feet of water off the coast of Monterey, California. Now, as scientists study the recently-discovered wreckage, dirigibles are returning to the Bay Area and are poised to rule the skies once again. But these aren’t the same dirigibles – these are new and improved.

In Volume 17, MAKE goes really old school with the Lost Knowledge issue, featuring projects and articles covering the steampunk scene — makers creating their own alternative Victorian world through modified computers, phones, cars, costumes, and other fantastic creations. Projects include an elegant Wimshurst Influence Machine (an electrostatic generator built entirely from Home Depot parts), a Florence Siphon coffee brewer, and a teacup-powered Stirling engine. This special section also covers watchmaking, letterpress printing, the early multimedia art of William Blake, and other wondrous and lost (or fading) pre-20th-century technologies.

Zeppelin NT is a German company seeking to revive the airship industry. They currently have four ships and have flown over 60,000 passengers to date. Zeppelin NT made the Airship Ventures ship that now flies out of Moffett Field (see below).

A Belgian engineer, Lieven Standaert, wants to develop self-sustaining air yachts that generate their own power:

The Aeromodeller II floats not on helium but on hydrogen, which has a dual function as fuel for the engines. The hydrogen is generated on board, while the ship hovers in the air and drops anchor at a height of 50 to 100 metres. This happens by means of a cable, similar to that of a kite. The zeppelin inverts its propellers, which then serve as windmills. They deliver the necessary energy to split water (coming from the ballast tanks and replenished by rain) into hydrogen and oxygen. Six hours of wind energy accumulate enough fuel for one hour of flying.

The Aeromodeller site is not in English, but Low Technology magazine has a nice piece about the project (from which the above excerpt was taken)

Jean-Marie Massaud is a French designer who’s designed a 690-foot dirigible shaped like a whale and planned as a floating luxury hotel dubbed the Manned Cloud.

The Aerofeather is a one-person airship that you’re strapped to the bottom of and fly by flapping your wings. Oh, you don’t have wings? No problem. They’ll provide you with a carbon-fiber and nylon pair. See a video of the Aerofeather in action here.

The site Girders and Gears has an excellent piece, Airship-Dirigible Model Designs, which looks at airship models that have appeared in mechanical toy building systems over the years (Erector Set, Mechano, etc.).
