Airships Of The United States
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air.A few airships after World War II used hydrogen. The first British airship to use helium was the ''Chitty Bang Bang'' of 1967. 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 accommodation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeppellin NT Amk
A Zeppelin is a type of rigid airship named after the German inventor Count 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 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 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 as bombers and as scouts, resulting in over 500 deaths in bombing raids in Britain. The defeat of Germany in 1918 temporarily slowed the airship business. Although DELAG establis ... [...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 ''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 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 long distance strategic bombers, launching numerous raids upon Belgium, France, and the United Kingdom. Following Count von Zeppelin's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Union
The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been described as a '' sui generis'' political entity (without precedent or comparison) combining the characteristics of both a federation and a confederation. Containing 5.8per cent of the world population in 2020, the EU generated a nominal gross domestic product (GDP) of around trillion in 2021, constituting approximately 18per cent of global nominal GDP. Additionally, all EU states but Bulgaria have a very high Human Development Index according to the United Nations Development Programme. Its cornerstone, the Customs Union, paved the way to establishing an internal single market based on standardised legal framework and legislation that applies in all member states in those matters, and only those matters, where the states have agreed to act ...

Moored Balloon
A tethered, moored or captive balloon is a balloon that is restrained by one or more tethers attached to the ground and so it cannot float freely. The base of the tether is wound around the drum of a winch, which may be fixed or mounted on a vehicle, and is used to raise and lower the balloon. A balloon is a form of aerostat, along with the powered free-flying airship, although the American GAO has used the term "aerostat" to describe a tethered balloon in contrast to the powered airship. Tethered balloons have been used for advertising, recreation, observation, and civil or military uses. Design principles Early balloons were simple round spheres, with a payload hung beneath. The round shape uses the minimum material to accommodate a given volume of lifting gas, making it the lightest construction. However, in any significant wind the round shape is aerodynamically unstable and will bob about, risking damage or the balloon breaking free. To avoid this problem, the kite ballo ...

Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Frederick Handley Page
Sir Frederick Handley Page, CBE, FRAeS (15 November 1885 – 21 April 1962) was an English industrialist who was a pioneer in the aircraft industry and became known as the father of the heavy bomber. His company Handley Page Limited was best known for its large aircraft such as the Handley Page 0/400 and Halifax bombers and the H.P.42 airliner. The latter was the flagship of the Imperial Airways fleet between the wars and remarkable at the time for having been involved in no passenger deaths. He is also known for his invention, with Gustav Lachmann, of the leading edge slot to improve the stall characteristics of aircraft wings. Frederick Handley Page was the uncle of World War II flying ace Geoffrey Page. Early life Handley Page was born in Cheltenham, the second son of Frederick Joseph Page, a furniture maker and member of the Plymouth Brethren. He was educated at Cheltenham Grammar School. In 1902, against his parents' wishes, he moved to London to study electrica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ezekiel Airship
The Ezekiel Airship was an early experimental aircraft conceived, designed, and built by the Baptist minister Burrell Cannon, an experienced sawmill operator born in 1848 in Coffeeville, Mississippi. Inspired by and named after the Book of Ezekiel, the craft's design featured four "wheel within a wheel" paddle wheels powered by a four-cylinder gasoline engine. There are unverified claims that it was flown in 1902 in Pittsburg, Texas, a year before the Wright Flyer flew at Kitty Hawk, North Carolina. On an unspecified Sunday in 1902, the aircraft is alleged to have flown approximately at a height of between and in the presence of only a handful of witnesses; there is, however, no physical evidence that such a flight ever took place. Historians have generally discounted claims that the airship ever flew, although some believe that it may have achieved uncontrolled flight. The original aircraft was destroyed in a storm near Texarkana, en route to St. Louis for the 1904 World's F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

LZ 129 Hindenburg
LZ 129 ''Hindenburg'' (; Registration: D-LZ 129) was a German commercial passenger-carrying rigid airship, the lead ship of the ''Hindenburg'' 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 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 from 1925 until his death in 1934. The airship flew from March 1936 until it was destroyed by fire 14 months later on May 6, 1937, while attempting to land at Lakehurst Naval Air Station in Manchester Township, New Jersey, at the end of the first North American transatlantic journey of its second season of service. This was the last of the great airship disasters; it was preceded by the crashes of the British R38, the US airship ''Roma ...

Hydrogen
Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula . It is colorless, odorless, tasteless, non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal matter.However, most of the universe's mass is not in the form of baryons or chemical elements. See dark matter and dark energy. Stars such as the Sun are mainly composed of hydrogen in the plasma state. Most of the hydrogen on Earth exists in molecular forms such as water and organic compounds. For the most common isotope of hydrogen (symbol 1H) each atom has one proton, one electron, and no neutrons. In the early universe, the formation of protons, the nuclei of hydrogen, occurred during the first second after the Big Bang. The emergence of neutral hydrogen atoms throughout the universe occurred about 370,000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Macon (ZRS-5)
USS ''Macon'' (ZRS-5) was a rigid airship built and operated by the United States Navy for scouting and served as a "flying aircraft carrier", designed to carry biplane parasite aircraft, five single-seat Curtiss F9C Sparrowhawk for scouting or two-seat Fleet N2Y-1 for training. In service for less than two years, in 1935 the ''Macon'' was damaged in a storm and lost off California's Big Sur coast, though most of the crew were saved. The wreckage is listed as the USS ''Macon'' Airship Remains on the U.S. National Register of Historic Places. Less than shorter than ''Hindenburg'', both ''Macon'' and her sister ship were among the largest flying objects in the world in terms of length and volume. Although both of the hydrogen-filled, Zeppelin-built ''Hindenburg'' and LZ 130 ''Graf Zeppelin II'' were longer, the two American-built sister naval airships still hold the world record for helium-filled rigid airships.
