The Zeppelin NT (''"Neue Technologie"'', German for ''new technology'') is a class of helium-filled airships being manufactured since the 1990s by the German company Zeppelin Luftschifftechnik GmbH (ZLT) in Friedrichshafen.〔 The initial model is the NT07. The company considers itself the successor of the companies founded by Ferdinand von Zeppelin which constructed and operated the very successful Zeppelin airships in the first third of the 20th century. There are, however, a number of notable differences between the Zeppelin NT and the airships of those days, as well as between the Zeppelin NT and usual non-rigid airships known as blimps. The Zeppelin NT is classified as a semi-rigid airship.〔(FAQs - Zeppelin vs. blimp ''(retrieved 13 January 2011)'' )〕 == Development == The modern development and construction was financed from an endowment, initially funded with money left over from the earlier Zeppelin company, that had been under the trusteeship of the Mayor of Friedrichshafen. A stipulation on the endowment limited use of its funds to the field of airships. Over the many years, the investment value of the endowment grew to a point where the time seemed right to use it for the design, development, and construction of a new Zeppelin. The initial design study was prepared in 1989. The ZLT was founded as a spin-off of the Zeppelin company in September 1993. It began to construct a prototype in 1995. The prototype first took to the air in September 1997. On July 2, 2000, the centennial of the first Zeppelin flight, the prototype ''SN 01'' was christened ''D-LZFN Friedrichshafen.'' Subsequently, it traveled some 3,600 km in test flights. In 2001 the company began manufacturing the Zeppelin NT in series and began to exploit the airships commercially. The second ship ''SN 02'' was christened ''D-LZZR Bodensee'' on August 10, 2001 and started to give joyrides five days later. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Zeppelin NT」の詳細全文を読む スポンサード リンク
