Unlike aerodynamic aircraft such as fixed-wing aircraft and helicopters, which produce lift by moving a wing through the air, aerostatic aircraft, such as airships and hot air balloons, stay aloft by filling a large cavity with a lifting gas or hot air.<\/p>\n<p>The main types of airship are non-rigid (or blimps), semi-rigid and rigid. Blimps are small airships without internal skeletons. Semi-rigid airships are slightly larger and have some form of internal support such as a fixed keel. Rigid airships with full skeletons, such as the huge Zeppelin transoceanic models.<\/p>\n<p>Metal-clad airships were of two kinds: rigid and non-rigid. Each kind used a thin gastight metal envelope, rather than the usual rubber-coated fabric envelope. Only four metal-clad ships are known to have been built, and only two actually flew: <img decoding=\"async\" loading=\"lazy\" class=\"alignleft\" title=\"The first rigged airship by the Hungarian David Schwartz\" src=\"http:\/\/balloon.hu\/tortenet\/picttort\/schwarclh.jpg\" alt=\"The first rigged airship by the Hungarian David Schwartz\" width=\"300\" height=\"247\" \/>The Hungarian David Schwarz&#8217;s first aluminum rigid airship of 1893 collapsed, while his second flew; the non-rigid ZMC-2 flew 1929 to 1941; while the 1929 non-rigid Slate &#8220;City of Glendale&#8221; collapsed on its first flight attempt.\u00a0After Schwarz&#8217;s death, his wife, Melanie Schwarz, was paid 15,000 marks by Count Ferdinand von Zeppelin for information about the airship.<\/p><!--CusAds0-->\n<p>Several companies build hot-air airships. These combine the structures of both hot-air balloons and small airships. The envelope is the normal &#8216;cigar&#8217; shape, complete with tail fins, but is inflated with hot air (as in a balloon) to provide the lifting force, instead of helium. A small gondola, carrying the pilot and passengers, a small engine, and the burners to provide the hot air are suspended below the envelope, below an opening through which the burners protrude.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignright\" title=\"Hot Airship\" src=\"http:\/\/balloon.hu\/mainpicts\/201007142664.jpg\" alt=\"Hot Airship\" width=\"400\" height=\"300\" \/>Hot-air airships typically cost less to buy and maintain than modern helium-based blimps, and can be quickly deflated after flights. This makes them easy to carry in trailers or trucks and inexpensive to store. They are usually very slow moving, with a typical top speed of 25\u201330 km\/h (15\u201320 mph, 6.7\u20138.9 m\/s). They are mainly used for advertising, but at least one has been used in rainforests for wildlife observation, as they can be easily transported to remote areas.<\/p>\n<!--CusAds0-->\n<div style=\"font-size: 0px; height: 0px; line-height: 0px; margin: 0; padding: 0; clear: both;\"><\/div>","protected":false},"excerpt":{"rendered":"<p>An airship or dirigible is a type of aerostat or &#8220;lighter-than-air aircraft&#8221; that can be steered and propelled through the air using rudders and propellers or other thrust mechanisms.
