Do the airships comeback?
The first driven, controlled flight in history is credited to the airship. September 24, 1852, Henri Giffard, Frenchman, 27 km (16.7 miles) from Paris to Trappes in his steam -powered airship. More than 50 years before the historic Wright Brothers flight, Giffard's flight is remembered less often due to the slow speed of airships due to the aircraft. This continued until 1937, when Hindenburg - the largest aircraft ever built at 250 meters (820 feet) - invaded the flames and accompanied great dramatic media attention, brought a decline in public faith in airship. Although the airship, which was intended to bear civilians, were not produced after the catastrophe in Hindenburg, the United States army built several hundred airship in the 20th century, which is used for training and convoy E and convoy E.Scort.
In 1997, the airship became a slight return with the start of Zeppelin nt . The new airship was created by Zeppelin Luftschiffftechnik GmbH (ZLG) based in Friedrichshafen, Germany. ZLG was founded in 1993 as a spinoff from the original Golden Age champions, Zeppelin Company. Since then, three Zeppelin NT have been produced, so far used only for Joyrides and advertising space. One was sold by Japanese companies.
Zeppelin NT, postavený na základu 60 let dodatečného technologického pokroku, je výrazně lepší než jeho předchůdci z hlediska bezpečnosti i nákladů. Instead of a strict entire aluminum frame, the NT uses a position -matching frame made primarily of carbon fibers, with aluminum beams. 75 meters long (246 feet) and only 1000 kilograms (2200 pounds), NT is filled with non -flammable, unreactive gas, helium. S maximálním užitečným zatížením a plnou palivovou nádrží není NT zcela lehčí než vzduch, což má za následek síť se dolů asi 600 kg (1 323 liber), která je negována nakloněním vrtulí mírně dolů během úrovně letu.
the air ship has a top speed of 125 km/h (77 km/h), with 70 km/h (44 mph) is a more typical speed flight. It is able to travel about 900 km (560 miles) without replenishing and stay at the top of almost 24 hours. Commercial flights offer DZR, a subsidiary ZLG. For several decades a year it operates around Lake Constance, which is adjacent to the city of Friedrichshafen. Flights range from half an hour to two hours, at a price of approximately 150 euros per hour.
Zeppelin NT can only be the beginning of the new golden age airships. Engineers and researchers around the world have begun to turn their attention back to the airship since the successful flight of 1997. Progress in fabrics, solar/fuel cells and batteries will soon make an airship on attractive platforms for observation and telecommunications. Only a few times slower than aircraft can be re -employed one day as a cheap means of transporting goods and passengers around the world. You could speculate that hundreds of new airships budou made before receiving the year 2020.
