The Zeppelin "LZ1" was the first truly successful experimental rigid airship, first flown from a floating hangar on Lake Constance, near Friedrichshafen in southern Germany, at 20:03editors at de.wikipedia.org, [http://de.wikipedia.org/wiki/Zeppelin#Der_erste_.E2.80.9EZeppelin.E2.80.9C] ] on 2 July 1900.Lueger, Otto: Lexikon der gesamten Technik und ihrer Hilfswissenschaften, Bd. 1 Stuttgart, Leipzig 1920., S. 404-412.

"LZ" stood for "Luftschiff Zeppelin", or "Airship Zeppelin".

Design and development

The LZ1 was convert|128|m|ft long, convert|11.7|m|ft in diameter and weighed 13 tons. It was constructed using a cylindrical framework covered with smooth surfaced cotton cloth. Inside was a row of 17 gas cells each covered in rubberized cloth. The hydrogen-gas capacity totaled convert|11300|m3|cuft.

The airship was steered by forward and aft rudders and propulsion was provided by two 15-hp Daimler internal-combustion engines, each rotating two propellers. The airship also employed a 130 kg weight suspended beneath the hull that could be slid forward or aft to control its attitude and about 300 kg ballast. Passengers and crew were carried in two 6.2 metre long aluminum gondolas suspended forward and aft.

Operational history

At its first trial the LZ1 carried five persons attaining an altitude of convert|400|m|ft and flew a distance of convert|6|km|mi in 18 minutes, but the wind then forced an emergency landing on the water. After repairs the ship flew two more times showing its potential, beating the speed record then held by the French Army airship, "La France", of convert|6|m/s|km/h by convert|3|m/s|km/h, but this could not convince the possible investors. Because funding was exhausted, Graf von Zeppelin had to dismantle the prototype, sell the scrap and tools and liquidate the company.
