Dirigible
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. Aerostats use buoyancy from a lifting gas that is less dense than the surrounding air to achieve the lift needed to stay airborne. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability, but the inherent flammability led to several fatal accidents that rendered hydrogen airships obsolete. The alternative lifting gas, helium gas is not flammable, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airship usage in North America. Most airships built since the 1960s have used helium, though some have used hot air. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has engines, crew, and optionally also payload ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeppelin
A Zeppelin is a type of rigid airship named after the German inventor Ferdinand von Zeppelin () who pioneered rigid airship development at the beginning of the 20th century. Zeppelin's notions were first formulated in 1874Eckener 1938, pp. 155–157. and developed in detail in 1893.Dooley 2004, p. A.187. They were patented in German Empire, Germany in 1895 and in the United States in 1899. After the outstanding success of the Zeppelin design, the word ''zeppelin'' came to be commonly used to refer to all forms of rigid airships. Zeppelins were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights. During World War I, the German military made extensive use of Zeppelins German strategic bombing during World War I, as bombers and aerial reconnaissance in World War I, as scouts. Numerous bombing raids on United Kingdom of Great Brita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luftschiffbau Zeppelin
Luftschiffbau Zeppelin GmbH is a German aircraft manufacturing company. It is perhaps best known for its leading role in the design and manufacture of rigid airships, commonly referred to as ''Zeppelin, Zeppelins'' due to the company's prominence. The name 'Luftschiffbau' is a German word meaning ''building of airships''. The company was founded by Count Ferdinand von Zeppelin in 1908 as a formal entity to continue advancing his pioneering research into rigid airships. ''Luftschiffbau Zeppelin'' became the leading manufacturer in the field of large lighter-than-air vehicles; its products were used in both military and civilian capacities. The firm founded DELAG, the List of airlines by foundation, world's first airline to use an aircraft in revenue service, in 1909 on the back of public interest and using its own airships. During the First World War, Zeppelins were employed as the first German strategic bombing during World War I, long distance strategic bombers, launching numerou ...

R101
R101 was one of a pair of British rigid airships completed in 1929 as part of the Imperial Airship Scheme, a British government programme to develop civil airships capable of service on long-distance routes within the British Empire. It was designed and built by an Air Ministry–appointed team and was effectively in competition with the government-funded but privately designed and built R100. When built, it was the world's largest flying craft at in length, and it was not surpassed by another hydrogen-filled rigid airship until the LZ 129 ''Hindenburg'' was launched seven years later. After trial flights and subsequent modifications to increase lifting capacity, which included lengthening the ship by to add another gasbag,"R101". Airship Heritage Trust via Airshipsonline.com.

Semi-rigid Airship
A semi-rigid airship is an airship which has a stiff keel or truss supporting the main envelope along its length. The keel may be partially flexible or articulated and may be located inside or outside the main envelope. The outer shape of the airship is maintained by gas pressure, as with the non-rigid "blimp". Semi-rigid dirigibles were built in significant quantity from the late 19th century but in the late 1930s they fell out of favour along with rigid airships. No more were constructed until the semi-rigid design was revived by the Zeppelin NT in 1997. Semi-rigid construction is lighter-weight than the outer framework of a rigid airship, while it allows greater loading than a non-rigid type. Principle More or less integrally attached to the hull are the gondola, engines and sometimes the empennage (tail). The framework has the task of distributing the suspension loads of these attachments and the lifting gas loads evenly throughout the whole hull's surface and may als ...

Rigid Airship
A rigid airship is a type of airship (or dirigible) in which the Aerostat, envelope is supported by an internal framework rather than by being kept in shape by the pressure of the lifting gas within the envelope, as in blimps (also called pressure airships) and semi-rigid airships. Rigid airships are often commonly called Zeppelins, though this technically refers only to airships built by the Luftschiffbau Zeppelin company. In 1900, Count Ferdinand von Zeppelin successfully performed the maiden flight of his first airship; further models quickly followed. Prior to the First World War, Germany was a world leader in the field, largely attributable to the work of von Zeppelin and his Luftschiffbau Zeppelin company. During the conflict, rigid airships were tasked with various military duties, which included their participation in German strategic bombing during World War I, Germany's strategic bombing campaign. Numerous rigid airships were produced and employed with relative commer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferdinand Von Zeppelin
Graf, Count Ferdinand von Zeppelin (; 8 July 1838 – 8 March 1917) was a General (Germany), German general and later inventor of the Zeppelin rigid airships. His name became synonymous with airships and dominated long-distance flight until the 1930s. He founded the company Luftschiffbau Zeppelin. Family and personal life Ferdinand was the scion of a . Zepelin, the family's eponymous hometown, is a small community outside the town of Bützow, in Mecklenburg. Ferdinand was the son of Württemberg Minister and Hofmarschall Friedrich Jerôme Wilhelm Karl Graf von Zeppelin (1807–1886) and his wife Amélie Françoise Pauline (born Macaire d'Hogguer) (1816–1852). Ferdinand spent his childhood with his sister and brother at their Girsberg manor near Konstanz, where he was educated by private tutors. Ferdinand married Isabella Freiin von Wolff in Berlin. She was from the house of Alt-Schwanenburg (located in the present-day town of Gulbene in Latvia, then part of Governorate of Li ...

Non-rigid Airship
A non-rigid airship, commonly called a blimp ( /blɪmp/), is an airship (dirigible) 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. Blimps are known for their use in advertising, surveillance, and observation due to their maneuverability, slow speeds and steady flight capabilities. Principle Since blimps keep their shape with internal overpressure, typically the only solid parts are the passenger car (gondola) and the tail fins. A non-rigid airship that uses heated air instead of a light gas (such as helium) as a lifting medium is called a hot-air airship (sometimes there are battens near the bow, which assist with higher forces there from a mooring attachment or from the greater aerodynamic pressures there). Volume changes of the lifting gas due to temperature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerostat
An aerostat (, via French) or lighter-than-air aircraft is an aircraft that relies on buoyancy to maintain flight. Aerostats include unpowered balloons (free-flying or tethered) and powered airships. The relative density of an aerostat as a whole is lower than that of the surrounding atmospheric air (hence the name "lighter-than-air"). Its main component is one or more gas capsules made of lightweight skins, containing a lifting gas (hot air, or any gas with lower density than air, typically hydrogen or helium) that displaces a large volume of air to generate enough buoyancy to overcome its own weight. Payload (passengers and cargo) can then be carried on attached components such as a basket, a gondola, a cabin or various hardpoints. With airships, which need to be able to fly against wind, the lifting gas capsules are often protected by a more rigid outer envelope or an airframe, with other gasbags such as ballonets to help modulate buoyancy. Aerostats are so named ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lift (physics)
When a fluid flows around an object, the fluid exerts a force on the object. Lift is the component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is the component of the force parallel to the flow direction. Lift conventionally acts in an upward direction in order to counter the force of gravity, but it is defined to act perpendicular to the flow and therefore can act in any direction. If the surrounding fluid is air, the force is called an aerodynamic force. In water or any other liquid, it is called a hydrodynamic force. Dynamic lift is distinguished from other kinds of lift in fluids. Aerostatic lift or buoyancy, in which an internal fluid is lighter than the surrounding fluid, does not require movement and is used by balloons, blimps, dirigibles, boats, and submarines. Planing lift, in which only the lower portion of the body is immersed in a liquid flow, is used by motorboats, surfboards, windsurfers, sailboa ...

Aircraft
An aircraft ( aircraft) is a vehicle that is able to flight, fly by gaining support from the Atmosphere of Earth, air. It counters the force of gravity by using either Buoyancy, static lift or the Lift (force), dynamic lift of an airfoil, or, in a few cases, direct Powered lift, downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), Glider (aircraft), gliders, Powered paragliding, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Aircrew, Crewed aircraft are flown by an onboard Aircraft pilot, pilot, whereas unmanned aerial vehicles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LZ 129 Hindenburg
LZ 129 ''Hindenburg'' (; Aircraft registration, Registration: D-LZ 129) was a German commercial passenger-carrying rigid airship, the lead ship of Hindenburg class airship, its class, the longest class of flying machine and the largest airship by envelope volume. It was designed and built by the Zeppelin Company (Luftschiffbau Zeppelin, ''Luftschiffbau Zeppelin GmbH'') on the shores of Lake Constance in Friedrichshafen, Germany, and was operated by the German Zeppelin Airline Company (''Deutsche Zeppelin-Reederei''). It was named after Field Marshal Paul von Hindenburg, who was President of Germany (1919–1945), President of Germany from 1925 until his death in 1934. The airship first flew from March 1936 as a #Die_Deutschlandfahrt, Nazi propaganda vessel until it Hindenburg disaster, burst into flames 14 months later on May 6, 1937, while attempting to land at Naval Air Engineering Station Lakehurst, Lakehurst Naval Air Station in Manchester Township, New Jersey, at the end ...
