Rigid Airship
A rigid airship is a type of airship (or dirigible) in which the 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 Germany's strategic bombing campaign. Numerous rigid airships were produced and employed with relative commercial success between the 1900s and the late 1930s. The ...

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] |
Lake Constance
Lake Constance (german: Bodensee, ) refers to three Body of water, bodies of water on the Rhine at the northern foot of the Alps: Upper Lake Constance (''Obersee''), Lower Lake Constance (''Untersee''), and a connecting stretch of the Rhine, called the Seerhein, Lake Rhine (''Seerhein''). These waterbodies lie within the Lake Constance Basin () in the Alpine Foreland through which the Rhine flows. The lake is situated where Germany, Switzerland, and Austria meet. Its shorelines lie in the German states of Baden-Württemberg and Bavaria, the Swiss cantons of Canton of St. Gallen, St. Gallen, Canton of Thurgau, Thurgau, and Canton of Schaffhausen, Schaffhausen, and the Austrian state of Vorarlberg. The actual location of the border Lake_Constance#International_borders, is disputed. The Alpine Rhine forms in its original course the Austro-Swiss border and flows into the lake from the south. The High Rhine flows westbound out of the lake and forms (with the exception of the Canton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zeppelin LZ1
The Zeppelin ''LZ 1'' was the first successful experimental rigid airship. It was first flown from a floating hangar on Lake Constance, near Friedrichshafen in southern Germany, on 2 July 1900.Lueger, Otto: Lexikon der gesamten Technik und ihrer Hilfswissenschaften, Bd. 1 Stuttgart, Leipzig 1920., S. 404–412Luftschiff/ref> "LZ" stood for ''Luftschiff Zeppelin'', or "Airship Zeppelin". Design and development Count Zeppelin had been devoting his energies to the design of large rigid-framed airships since his retirement from the army in 1890. In 1898 he established the Gesellschaft zur Förderung der Luftschifffahrt. The company had a subscribed capital of 800,000 Deutschmarks, of which Zeppelin contributed 300,000 Deutschmarks: the remainder was provided by various industrialists, including 100,000 Deutschmarks contributed by Carl Berg, whose company provided the aluminium framework of the airship. The company first constructed a large floating shed to contain the airship. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Berg (airship Builder)
Carl Berg (4 February 1851, Lüdenscheid – 26 May 1906, Bonn) was a German entrepreneur and airship builder. Berg came from a commercial iron-works family. His great grandfather founded a button-making factory on 1786 in Lüdenscheid. In the following generations the factory developed into an important metal-working company. Among others it incorporated a brass works and an iron works in Eveking (today Werdohl). After his father's death Carl Berg, at the age of 20, took over the firm and expanded it further. Early on he recognised the opportunities in the electrical industries and delivered special wire for the Post to use for telegraph and telephone. Other non-ferrous metals were developed. Berg founded as subsidiaries the copperworks "Deutschland" in Berlin and "Österreich" in Außig (part of Cavertitz, in Bohemia). Above all he realised the advantages of aluminium as a light building material and his Lüdenscheid firm became a pioneer of the aluminium industry. In 18 ...

David Schwarz (aviation Inventor)
David Schwarz ( hu, Schwarz Dávid; hr, David Švarc, ;''David'' in isolation: . 20 December 1850 – 13 January 1897)Ernst Heinrich Hirschel, Horst Prem, Gero Madelung, ''Aeronautical Research in Germany: From Lilienthal until Today'', "The Controllable Airship - The Dirigible", pp. 24-25. Springer-Verlag Berlin Heidelberg, 2004, (eBook ) was a Hungarian aviation pioneer. He is known for creating an airship with a rigid envelope made entirely of metal. Schwarz died only months before the airship was flown. Some sources have claimed that Count Ferdinand Graf von Zeppelin purchased Schwarz's airship patent from his widow, a claim which has been disputed. He was the father of the opera and operetta soprano Vera Schwarz (1888–1964). Birth date and nationality Sources for his date of birth vary. The OCLC cites Rotem, Ẓ. giving it as 7 December 1850, while Brockhaus gives it as 20 December 1850 The OCLC, as well as Brockhaus, show Schwarz's place of birth as Zalaegerszeg, Hunga ...

Joseph Spiess (engineer)
Joseph Spiess (10 September 1838 – 31 March 1917) was a French engineer who filed a patent for a rigid airship in 1873, the year before Ferdinand von Zeppelin first outlined his own design. However, Spiess's machine was not actually constructed until 1913, and was the first and only French rigid airship. Biography Spiess was the son of a printer, in Mulhouse, Haut-Rhin département, in the Alsace region of France. He served as a warrant officer in the Franco-Prussian War from 1870 to 1871, and when Alsace-Lorraine was annexed by the German Empire, Spiess opted to retain his French nationality. Shortly before World War I, there was public pressure for France to emulate Germany's airship fleet, and construction of Spiess's airship, with state assistance, was started by Société Zodiac at the Aérodrome de Saint-Cyr-l'École. It had a framework of hollow wooden spars braced with wire, and was given the name ''Zodiac XII'' but had the name ''"SPIESS"'' painted along the s ...

Elevator (aircraft)
Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer. They may be the only pitch control surface present, and are sometimes located at the front of the aircraft (early airplanes) or integrated into a rear "all-moving tailplane", also called a slab elevator or stabilator. Elevator control effectiveness The elevator is a usable up and down system that controls the plane, horizontal stabilizer usually creates a ''downward'' force which balances the nose down moment created by the wing lift force, which typically applies at a point (the wing center of lift) situated aft of the airplane's center of gravity. The effects of drag and changing the engine thrust may also result in pitch moments that need to be compensated with the horizontal stabilizer. Both the horizontal stabilizer and ...

Lift (force)
A fluid flowing around an object exerts a force on it. 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 can act in any direction at right angles to the flow. 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, sailboats, and water-skis. Overview A fluid flowing arou ...
