Like all modern airships, helium is the lifting gas. [2] The AS700 has an ellipsoid hull, with a rigid tail configuration done in an "X" positioning rather than the traditional "+" positioning. [2] The design is considered as a light and cost-effective capsule-shaped airship. [3] The tail has flight control surfaces to allow in ease in steering.
The cost included the design, development, and testing of the airship system within an 18-month time period, followed by transport to Afghanistan for military assessment. [10] Throughout development, technological challenges and multiple delays were encountered.
In 1995, the Luftfahrt-Bundesamt, Germany's civil aviation authority, officially recognized ZLT as a design organisation, and approved new construction regulations for airships. In November 1995, final assembly of the first airship prototype commenced, it was promoted as being the first rigid airship to be produced by the firm since the Second ...
LOTTE airship model. LOTTE airship is the world's first autonomous solar-powered airship and has been certified under the registration number D-UISD, which was developed in close cooperation with the Federal Aviation Authority in Braunschweig, Germany, as there were no guidelines for the certification of solar-powered airships at the time of its construction.
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.
The P-791 was designed as part of the U.S. Army's Long Endurance Multi-intelligence Vehicle (LEMV) program, but lost the program's competition to Northrop Grumman's HAV-3 design. The P-791 was modified to be a civil cargo aircraft under the name SkyTug, with a lift capability of 20 short tons (18,000 kg) and plans to scale larger.
A hybrid airship is a powered aircraft that obtains some of its lift as a lighter-than-air (LTA) airship and some from aerodynamic lift as a heavier-than-air aerodyne. A dynastat is a hybrid airship with fixed wings and/or a lifting body and is typically intended for long-endurance flights. It requires forward flight to create the aerodynamic ...
A non-rigid airship relies entirely on internal gas pressure to retain its shape during flight. Unlike the rigid design, the non-rigid airship's gas envelope has no compartments. However, it still typically has smaller internal bags containing air . As altitude is increased, the lifting gas expands and air from the ballonets is expelled through ...
