R38
The ''R.38'' class (also known as the ''A'' class) of rigid airships was designed for Britain's Royal Navy during the final months of the First World War, intended for long-range patrol duties over the North Sea. Four similar airships were originally ordered by the Admiralty, but orders for three of these (''R.39'', ''R.40'' and ''R.41'') were cancelled after the armistice with Germany and ''R.38'', the lead ship of the class, was sold to the United States Navy in October 1919 before completion. On 24 August 1921, ''R.38'' (designated ZR-2 by the USN) was destroyed by a structural failure while in flight over the city of Hull. It crashed into the Humber Estuary, killing 44 out of the 49 crew aboard and one black cat named Snowball. At the time of its first flight it was the world's largest airship. Its destruction was the first of the great airship disasters, followed by the Italian-built US semi-rigid airship ''Roma'' in 1922 (34 dead), the French '' Dixmude'' in 1923 (52 de ...

Sunbeam Cossack
The Sunbeam Cossack was a British 12-cylinder aero engine that was first run in 1916. The Cossack spawned a family of engines from Sunbeam. Design and development As the First World War raged through 1914 and 1915, The Admiralty demanded engines with more power for its existing and future aircraft. The problem was exemplified by the Short Type 184 seaplanes of the RNAS, powered by Sunbeam Mohawk engines, which could barely lift the standard air-dropped torpedo with crew reduced to two and minimal fuel. An engine with a base rating of at least was demanded by the Admiralty. Responses came from Rolls-Royce with the Rolls-Royce Eagle and Sunbeam with the Sunbeam Cossack. Louis Coatalen designed the Cossack as a twin overhead camshaft 60° V-12, with four valves per cylinder, bore of and stroke of . Output from the Cossack was at 2,000rpm, with a running weight of , driving a large diameter propeller through a 2:1 reduction gear. Construction of the Cossack was largely of al ...

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.

Zeppelins
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] |
Humber
The Humber is a large tidal estuary on the east coast of Northern England. It is formed at Trent Falls, Faxfleet, by the confluence of the tidal rivers River Ouse, Yorkshire, Ouse and River Trent, Trent. From there to the North Sea, it forms part of the boundary between the East Riding of Yorkshire on the north bank and North Lincolnshire on the south bank. Also known as the River Humber, it is tidal its entire length. Below Trent Falls, the Humber passes the junction with the Market Weighton Canal on the north shore, the confluence of the River Ancholme on the south shore; between North Ferriby and South Ferriby and under the Humber Bridge; between Barton-upon-Humber on the south bank and Kingston upon Hull on the north bank (where the River Hull joins), then meets the North Sea between Cleethorpes on the Lincolnshire side and the long and thin headland of Spurn, Spurn Head to the north. Ports on the Humber include the Port of Hull, the Port of Grimsby and the Port of Immin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Airship
An airship, dirigible balloon or dirigible is a type of aerostat (lighter-than-air) aircraft that can navigate through the air flying powered aircraft, under its own power. Aerostats use buoyancy from a lifting gas that is less dense than the surrounding air to achieve the lift (physics), lift needed to stay airborne. In early dirigibles, the lifting gas used was hydrogen gas, 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 thermal airship, hot air. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dixmude (airship)
''Dixmude'' was a Zeppelin airship built for the Imperial German Navy as L 72 (c/n ''LZ 114'') and unfinished at the end of the First World War, when it was given to France as war reparations and recommissioned for service in the French Navy and renamed ''Dixmude''. The airship was lost when it exploded in mid-air on 21 December 1923 off the coast of Sicily, killing all 52 (42 crew and ten passengers) on board. This was one of the earliest of the great airship disasters, preceded by the crash of the British '' R38'' in 1921 (44 dead) and the US airship ''Roma'' in 1922 (34 dead), and followed by the destruction of the USS ''Shenandoah'' in 1925 (14 dead) the British ''R101'' in 1930 (48 dead), the USS ''Akron'' in 1933 (73 dead) and the German ''Hindenburg'' in 1937 (36 dead). Name The ship was named after the Belgian city of Diksmuide (French: ''Dixmude''), and specifically, in honour of the Fusiliers Marins at the battle of Diksmuide. It was the first of three ships na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short Brothers
Short Brothers plc, usually referred to as Shorts or Short, is an aerospace company based in Belfast, Northern Ireland. Shorts was founded in 1908 in London, and was the first company in the world to make production aeroplanes. It was particularly notable for its flying boat designs manufactured into the 1950s. In 1943, Shorts was Nationalization, nationalised and later denationalised, and in 1948 moved from its main base at Rochester, Kent to Belfast. In the 1960s, Shorts mainly produced turboprop airliners, major components for aerospace primary manufacturers, and missiles for the British Armed Forces. Shorts was primarily HM Government, government-owned until being bought by Bombardier Inc., Bombardier in 1989 and, in 2007, was the largest manufacturing concern in Northern Ireland. In November 2020, Bombardier sold its Belfast operations to Spirit AeroSystems. The company's products include aircraft components, engine nacelles and aircraft flight control systems for Bomba ...

USS Los Angeles (ZR-3)
USS ''Los Angeles'' was a rigid airship, designated ZR-3, which was built in 1923–1924 by the Luftschiffbau Zeppelin, Zeppelin company in Friedrichshafen, Germany, as war reparations. She was delivered to the United States Navy in October 1924 and after being used mainly for experimental work, particularly in the development of the American parasite fighter program, was decommissioned in 1932. Design The second of USS Los Angeles, four vessels to carry the name USS ''Los Angeles'', the airship was built for the United States Navy as a replacement for the Zeppelins that had been assigned to the United States as war reparations following World War I, and had been sabotaged by their crews in 1919. Under the terms of the Treaty of Versailles Luftschiffbau Zeppelin were not permitted to build military airships. In consequence ''Los Angeles'', which had the Zeppelin works number LZ 126, was built as a passenger airship, although the treaty limitation on the permissible volume ...

War Reparations
War reparations are compensation payments made after a war by one side to the other. They are intended to cover damage or injury inflicted during a war. War reparations can take the form of hard currency, precious metals, natural resources, industrial assets, or intellectual properties. Loss of territory in a peace settlement is usually considered to be distinct from war reparations. War reparations are often governed by treaties which belligerent parties negotiate as part of a peace settlement. Payment of reparations often occur as part of a condition to remove occupying troops or under the threat of re-occupation. The legal basis for war reparations in modern international law is Article 3 of the Hague Convention of 1907. Prominent examples of war reparations include Carthage's indemnity paid to Rome following the First Punic War, French reparations following the Napoleonic Wars, Haiti's reparations to France following the Haitian War of Independence (1791–1804), Fren ...

Scuttling Of The German Fleet At Scapa Flow
On 21 June 1919, shortly after the end of the First World War, the Imperial German Navy's High Seas Fleet was scuttled by its sailors while held off the harbour of the British Royal Navy base at Scapa Flow, in the Orkney Islands of Scotland. The fleet was interned there under the terms of the Armistice of 11 November 1918 while negotiations took place over its fate. Fearing that either the British would seize the ships unilaterally or the German government at the time might reject the Treaty of Versailles and resume the war effort (in which case the ships could be used against Germany), Admiral Ludwig von Reuter decided to scuttle the fleet. Intervening British guard ships were able to beach some of the ships, but 52 of the 74 interned vessels sank. Many of the wrecks were salvaged over the next two decades and were towed away for scrapping. Those that remain are popular diving sites and a source of low-background steel.
