An airship is a powered, free-flying aerostat that can be steered. Airships divide into rigid, semi-rigid and non-rigid types, with these last often known as blimps. A rigid airship has an outer framework or skin surrounding the lifting gas bags inside it, The outer envelope keeps its shape even if the gasbags are deflated.
The Aircruise would be a solar and hydrogen fuel cell-powered airship. [4] According to its design specifications, it would be 265 m (869 ft) tall containing 330,000 m 3 (12,000,000 cu ft) of air and would carry a payload of 396 t (390 long tons; 437 short tons).
The Giffard dirigible or Giffard airship was an airship built in France in 1852 by Henri Giffard, it was the first powered and steerable airship to fly. The craft featured an elongated hydrogen -filled envelope that tapered to a point at each end.
The amount of mass that can be lifted by hydrogen in air per unit volume at sea level, equal to the density difference between hydrogen and air, is: (1.292 - 0.090) kg/m 3 = 1.202 kg/m 3. and the buoyant force for one m 3 of hydrogen in air at sea level is: 1 m 3 × 1.202 kg/m 3 × 9.8 N/kg= 11.8 N
Euro Airship is planning an around-the-world, non-stop flight with Solar Airship One. It would be the first flight to make the trip without using fossil fuels.
A modern airship, Zeppelin NT D-LZZF in 2010 The LZ 129 Hindenburg was the largest airship ever built and was destroyed in 1937. Dirigible airships compared with related aerostats, from the Brockhaus and Efron Encyclopedic Dictionary, 1890–1907
During the 1930s, airships like the Hindenburg class were widely considered the future of air travel, [citation needed] and the lead ship of the class, LZ 129 Hindenburg, established a regular transatlantic service. The airship's destruction in a highly publicized accident was the end of these expectations.
