A non-rigid airship, commonly called a blimp , is an airship (dirigible) [1] without an internal structural framework or a keel. Unlike semi-rigid and rigid airships (e.g. Zeppelins ), blimps rely on the pressure of their lifting gas (usually helium , rather than flammable hydrogen ) and the strength of the envelope to maintain their shape.
The term blimp itself is defined as a non-rigid airship—without any internal structure, the pressure of lifting gas within the airship envelope maintains the vessel's shape. From the launch of the Pilgrim in 1925 to the retiring of the Spirit of Innovation in 2017, Goodyear generally owned and operated non-rigid airships in its global public ...
NAS blimp bases, (Navy Air Stations Blimps bases), were United States Navy blimp bases built to protect coastal waters during World War II. Navy Blimps could stay in the air and patrol coastal waters much longer than airplanes .
The airship was 403 ft (122.8 m) long and was almost 120 ft (36.6 m) high, containing some 1,500,000 cubic feet (42,450 cubic meters). [6] The endurance time of the airship could extend for days. This model of the N-class blimp was the largest non-rigid airship ever flown. The ZPG-3W Vigilance was the last of the airships built for the U.S ...
The K-class blimp was a class of blimps (non-rigid airship) built by the Goodyear Aircraft Company of Akron, Ohio, for the United States Navy.These blimps were powered by two Pratt & Whitney Wasp nine-cylinder radial air-cooled engines, each mounted on twin-strut outriggers, one per side of the control car that hung under the envelope.
The helium-filled blimps are fitted with solar panels and backup batteries to power their engines, have a flight time of up to 12 hours and a range of up to 400 kilometers (249 miles), flying at a ...
An airship, dirigible balloon or dirigible is a type of aerostat (lighter-than-air) aircraft that can navigate through the air flying under its own power. [1]
