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] |

Hydrogen
Hydrogen is a chemical element; it has chemical symbol, symbol H and atomic number 1. It is the lightest and abundance of the chemical elements, most abundant chemical element in the universe, constituting about 75% of all baryon, normal matter. Under standard conditions, hydrogen is a gas of diatomic molecules with the chemical formula, formula , called dihydrogen, or sometimes hydrogen gas, molecular hydrogen, or simply hydrogen. Dihydrogen is colorless, odorless, non-toxic, and highly combustible. Stars, including the Sun, mainly consist of hydrogen in a plasma state, while on Earth, hydrogen is found as the gas (dihydrogen) and in molecular forms, such as in water and organic compounds. The most common isotope of hydrogen (H) consists of one proton, one electron, and no neutrons. Hydrogen gas was first produced artificially in the 17th century by the reaction of acids with metals. Henry Cavendish, in 1766–1781, identified hydrogen gas as a distinct substance and discovere ... [...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 Ferdinand von Zeppelin, Zeppelin". Design and development Ferdinand von Zeppelin, 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 (airship builder), Carl Berg, whose company provided the aluminium framework of the airship.

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 (; , ;''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). Personal life Schwarz was born in Keszthely, Kingdom of Hungary, then part of the Austrian Empire He was a timber merchant raised in Županja, but he spent most of his life in Zagreb, Kingdom of Croatia-Slavonia. He was Jewish. Sources for his date of birth vary. The OCLC cites Rot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Zodiac Aerospace, 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"'' pai ...

United States Department Of War
The United States Department of War, also called the War Department (and occasionally War Office in the early years), was the United States Cabinet department originally responsible for the operation and maintenance of the United States Army, also bearing responsibility for naval affairs until the establishment of the United States Department of the Navy, Navy Department in 1798, and for most land-based air forces until the creation of the United States Department of the Air Force, Department of the Air Force on September 18, 1947. The United States Secretary of War, secretary of war, a civilian with such responsibilities as finance and purchases and a minor role in directing military affairs, headed the War Department throughout its existence. The War Department existed for 158 years, from August 7, 1789, to September 18, 1947, when it split into the United States Department of the Army, Department of the Army and the United States Department of the Air Force, Department of the ...

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 and canards) 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 ...

Lift (force)
When a fluid flows around an object, the fluid exerts a force on the object. Lift is the Euclidean_vector#Decomposition_or_resolution, component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag (physics), 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 Fluid dynamics, hydrodynamic force. Dynamic lift is distinguished from other kinds of lift in fluids. Aerostatics, 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 (boat), Planing lift, in which only the lower po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
