R31 (airship)
The ''R31'' class of British rigid airships was constructed in the closing months of World War I, and comprised two aircraft, His Majesty's Airship ''R31'' and ''R32''. They were designed by the Royal Corps of Naval Constructors – with assistance from a Herr Müller who had defected to Britain, and previously worked for the Schütte-Lanz airship company – and built by Short Brothers at the Cardington airship sheds. The airship frame was made from spruce plywood laminated into girder sections, weatherproofed with varnish, and also fireproofed. These enclosed 21 gas bags. Airship Heritage Trust R31 ''R31'' was the largest British airship to fly before the end of the war, and the class remains the largest mobile wooden structures ever built. As the airships were intended for fleet protection operations, they were to be fitted with defensive machine guns on top of the envelope, at the stern and in the gondolas. A 12-pounder gun was to be fitted in a special position centrally b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plywood
Plywood is a material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which include medium-density fibreboard (MDF), oriented strand board (OSB) and particle board (chipboard). All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. This alternation of the grain is called ''cross-graining'' and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1910s British Patrol Aircraft
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

R80 (airship)
The ''R.80'' was a British rigid airship, first flown on 19 July 1920, and was the first fully streamlined airship to be built in Britain. Originally a military project for the British Admiralty, it was completed for commercial passenger-carrying. ''R.80'' proved too small for this role and after being used briefly to train the United States Navy personnel who were to crew the ''ZR-2'' airship, ''R.80'' was retired and eventually scrapped in 1925. Development Construction was begun by Vickers in their airship shed at Walney Island, Barrow-in-Furness, in November 1917 to a design by Barnes Wallis and H. B. Pratt. Vickers had originally contracted to build '' R.37'', but due to a lack of vacant sheds and a war-time steel shortage preventing construction of a new larger one, the smaller shed at Walney was used instead. This had been used to build '' R.27'' and '' R.29'', and the size of the R.80 was limited by the small size of the shed. Work progressed slowly due to labour short ...

R38 (ZR-2)
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. 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 dead), the USS ''Shenandoah'' i ...

Royal Air Force
The Royal Air Force (RAF) is the United Kingdom's air and space force. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by regrouping the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security".

R33 Class Airship
The R.33 class of British rigid airships were built for the Royal Naval Air Service during the First World War, but were not completed until after the end of hostilities, by which time the RNAS had become part of the Royal Air Force. The lead ship, R.33, served successfully for ten years and survived one of the most alarming and heroic incidents in airship history when she was torn from her mooring mast in a gale. She was called a "Pulham Pig" by the locals, as the blimps based there had been, and is immortalised in the village sign for Pulham St Mary. The only other airship in the class, R.34, became the first aircraft to make an east to west transatlantic flight in July 1919 and, with the return flight, made the first two-way crossing. It was decommissioned two years later, after being damaged during a storm. The crew nicknamed her "Tiny". Design and development Substantially larger than the preceding R31 class, the R.33 class was in the design stage in 1916 when the German ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
R23X Class Airship
The British R.23X class of rigid airships were developed during World War I using the experiences gained from the 23 class, but only two of the planned four R.23X class were built: ''R.27'' and ''R.29''. Both were completed mid-1918, but just months after entering service ''R.27'' was destroyed by fire in a hangar; while ''R.29'' went on to become the most successful British wartime rigid airship, being the only one to meet enemy action, as well as the only one to sink a submarine.HMA 23X Airship Heritage Trust.

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 ...
