HMA No. 9r
HMA ''No. 9r'' was a rigid airship designed and built by Vickers at Walney Island just off Barrow-in-Furness, Cumbria. It was ordered in 1913 but did not fly until 27 November 1916 when it became the first British rigid airship to do so. It was dismantled in June 1918 after being flown for around 165 hours, mainly for experimental purposes. Background Plans to build a second rigid airship to follow the unsuccessful HMA No. 1 (His Majesty's Airship No. 1) ''Mayfly'' were agreed by the Committee for Imperial Defence in early 1913, and that Vickers should be asked to design an improved class of ship incorporating all that was then known about the Zeppelins. Vickers' airship design department had been disbanded following the failure of the ''Mayfly'', consequently a new department was formed when the original design team was reassembled with H. B. Pratt recruited as chief designer. Pratt had been working at Vickers while the ''Mayfly'' was being constructed and had predicted that ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ...

Mooring Mast
A mooring mast, or mooring tower, is a structure designed to allow for the docking of an airship outside of an airship hangar or similar structure. More specifically, a mooring mast is a mast or tower that contains a fitting on its top that allows for the bow of the airship to attach its mooring line to the structure. When it is not necessary or convenient to put an airship into its hangar (or shed) between flights, airships can be moored on the surface of land or water, in the air to one or more wires, or to a mooring mast. After their development mooring masts became the standard approach to mooring airships as considerable manhandling was avoided.Williams, T, 2009 (Reissue), "Airship Pilot No. 28", Darcy Press, UK, Mast types Airship mooring masts can be broadly divided into fixed high masts and fixed or mobile low (or ‘stub’) masts. In the 1920s and 1930s masts were built in many countries. At least two were mounted on ships. Without doubt the tallest mooring mast ...

Norfolk
Norfolk () is a ceremonial and non-metropolitan county in East Anglia in England. It borders Lincolnshire to the north-west, Cambridgeshire to the west and south-west, and Suffolk to the south. Its northern and eastern boundaries are the North Sea, with The Wash to the north-west. The county town is the city of Norwich. With an area of and a population of 859,400, Norfolk is a largely rural county with a population density of 401 per square mile (155 per km2). Of the county's population, 40% live in four major built up areas: Norwich (213,000), Great Yarmouth (63,000), King's Lynn (46,000) and Thetford (25,000). The Broads is a network of rivers and lakes in the east of the county, extending south into Suffolk. The area is protected by the Broads Authority and has similar status to a national park. History The area that was to become Norfolk was settled in pre-Roman times, (there were Palaeolithic settlers as early as 950,000 years ago) with camps along the highe ...

RNAS Pulham
RNAS Pulham (later RAF Pulham) was a Royal Navy Air Service (RNAS) airship station, near Pulham St Mary south of Norwich, UK. Though land was purchased by the Admiralty in 1912 the site was not operational until 1915. From 1918 to 1958, the unit was a Royal Air Force establishment. The land today is in private ownership, and little remains above ground. However, the Pennoyer Centre in Pulham St Mary holds an extensive archive of photographs and memorabilia relating to the Air Station. History Pulham was one of the main British airship stations, with more than 3,000 men on the base at the end of the First World War. Initially it was used for airships that operated patrols over the North Sea (such as the Coastal and SS types) until their areas were taken over by seaplanes. The R34 landed at RNAS Pulham to complete the first two-way flown crossing of the Atlantic in July 1919. After the loss of the R101 in 1930 and the end of British airships the station was moved on to a ca ...

RNAS Howden
RNAS Howden (later RAF Howden) was an airship station near the town of Howden south-east of York, England. History It was opened in March 1916 to cover the East Coast ports shipping from attacks by German U-boats during the First World War, with its first airship, the Coastal-class non-rigid airship arriving on 26 June 1916. From 1916 to 1918 Howden was a Royal Naval Air Service establishment, with the base transferring to the Royal Air Force when it was established on 1 April 1918. While airships flew on patrols from Howden until the end of the war, Howden-based airships never engaged in direct combat with German submarines.Delve 2006, p. 295. The station remained operational after the end of the war, with operations continuing to support minesweeping operations over the North Sea.Delve 2006, pp. 295–296. A new hangar, at the time the largest in the world, was completed in 1919. The No.2 Double Rigid Shed measured in length and clearance height. In 1921, the rigid ai ...

RNAS
The Royal Naval Air Service (RNAS) was the air arm of the Royal Navy, under the direction of the Admiralty's Air Department, and existed formally from 1 July 1914 to 1 April 1918, when it was merged with the British Army's Royal Flying Corps to form the Royal Air Force (RAF), the world's first independent air force. It was replaced by the Fleet Air Arm, initially consisting of those RAF units that normally operated from ships, but emerging as a separate unit similar to the original RNAS by the time of World War 2. Background In 1908, the British Government recognised the military potential of aircraft. The Prime Minister, H. H. Asquith, approved the formation of an "Advisory Committee for Aeronautics" and an "Aerial Sub-Committee of the Committee of Imperial Defence". Both committees were composed of politicians, army officers and Royal Navy officers. On 21 July 1908 Captain Reginald Bacon, who was a member of the Aerial Navigation sub-committee, submitted to the First Sea L ...

Essex
Essex () is a county in the East of England. One of the home counties, it borders Suffolk and Cambridgeshire to the north, the North Sea to the east, Hertfordshire to the west, Kent across the estuary of the River Thames to the south, and Greater London to the south and south-west. There are three cities in Essex: Southend, Colchester and Chelmsford, in order of population. For the purposes of government statistics, Essex is placed in the East of England region. There are four definitions of the extent of Essex, the widest being the ancient county. Next, the largest is the former postal county, followed by the ceremonial county, with the smallest being the administrative county—the area administered by the County Council, which excludes the two unitary authorities of Thurrock and Southend-on-Sea. The ceremonial county occupies the eastern part of what was, during the Early Middle Ages, the Anglo-Saxon Kingdom of Essex. As well as rural areas and urban areas, it forms ...

Easter Rising
The Easter Rising ( ga, Éirí Amach na Cásca), also known as the Easter Rebellion, was an armed insurrection in Ireland during Easter Week in April 1916. The Rising was launched by Irish republicans against British rule in Ireland with the aim of establishing an independent Irish Republic while the United Kingdom was fighting the First World War. It was the most significant uprising in Ireland since the rebellion of 1798 and the first armed conflict of the Irish revolutionary period. Sixteen of the Rising's leaders were executed from May 1916. The nature of the executions, and subsequent political developments, ultimately contributed to an increase in popular support for Irish independence. Organised by a seven-man Military Council of the Irish Republican Brotherhood, the Rising began on Easter Monday, 24 April 1916 and lasted for six days. Members of the Irish Volunteers, led by schoolmaster and Irish language activist Patrick Pearse, joined by the smaller Irish Citizen Arm ...

Hemp
Hemp, or industrial hemp, is a botanical class of ''Cannabis sativa'' cultivars grown specifically for industrial or medicinal use. It can be used to make a wide range of products. Along with bamboo, hemp is among the fastest growing plants on Earth. It was also one of the first plants to be spun into usable fiber 50,000 years ago. It can be refined into a variety of commercial items, including paper, rope, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed. Although chemotype I cannabis and hemp (types II, III, IV, V) are both ''Cannabis sativa'' and contain the psychoactive component tetrahydrocannabinol (THC), they represent distinct cultivar groups, typically with unique phytochemical compositions and uses. Hemp typically has lower concentrations of total THC and may have higher concentrations of cannabidiol (CBD), which potentially mitigates the psychoactive effects of THC. The legality of hemp varies widely among countrie ...

Blimp
A blimp, or non-rigid airship, 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 the lifting gas (usually helium, rather than hydrogen) inside the envelope and the strength of the envelope itself to maintain their shape. 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 changes or to changes of altitude are compensated for by pumping air into internal ballonets (air bags) to maintain the overpressure. Without sufficient overpressur ...
