Walter Gordon Wilson
Major Walter Gordon Wilson (21 April 1874 – 1 July 1957) was an Irish mechanical engineer, inventor and member of the British Royal Naval Air Service. He was credited by the 1919 Royal Commission on Awards to Inventors as the co-inventor of the tank, along with Sir William Tritton. Education Walter was born in Blackrock, County Dublin, on 21 April 1874. In 1888 he enlisted as a midshipman on HMS ''Britannia'', but resigned in 1892. In 1894 he entered King's College, Cambridge, where he studied the mechanical sciences tripos, graduating with a first class degree, B.A., in 1897. Wilson acted as 'mechanic' for the Hon C. S. Rolls on several occasions while they were undergraduates in Cambridge. Aero engine 1898 Interested in powered flight, he collaborated with Percy Sinclair Pilcher and the Hon Adrian Verney-Cave later Lord Braye to attempt to make an aero-engine from 1898. The engine was a flat-twin air cooled and weighed only 40 lb, but shortly before a demonstratio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Major (United Kingdom)
Major (Maj) is a military rank which is used by both the British Army and Royal Marines. The rank is superior to Captain (British Army and Royal Marines), captain and subordinate to Lieutenant colonel (United Kingdom), lieutenant colonel. The insignia for a major is a Crown (headgear), crown. The equivalent rank in the Royal Navy is Lieutenant commander (Royal Navy), lieutenant commander, and squadron leader in the Royal Air Force. History By the time of the Napoleonic Wars, Napoleonic wars, an infantry battalion usually had two majors, designated the "senior major" and the "junior major". The senior major effectively acted as second-in-command and the majors often commanded detachments of two or more company (military unit), companies split from the main body. The second-in-command of a battalion or regiment is still a major.

Crankshaft
A crankshaft is a mechanical component used in a reciprocating engine, piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating Shaft (mechanical engineering), shaft containing one or more crankpins, that are driven by the pistons via the connecting rods. The crankpins are also called ''rod bearing journals'', and they rotate within the "big end" of the connecting rods. Most modern crankshafts are located in the engine block. They are made from steel or cast iron, using either a forging, casting (metalworking), casting or machining process. Design The crankshaft is located within the engine block and held in place via main bearings which allow the crankshaft to rotate within the block. The up-down motion of each piston is transferred to the crankshaft via connecting rods. A flywheel is often attached to one end of the crankshaft, in order to smoothen the power delivery and reduce vibration. A crankshaft is subjected to enormou ...

Landship Committee
The Landship Committee was a small British committee formed during the First World War to develop armoured fighting vehicles for use on the Western Front. The eventual outcome was the creation of what is now called the tank. Established in February 1915 by First Lord of the Admiralty Winston Churchill, the Committee was composed mainly of naval officers, politicians and engineers. It was chaired by Eustace Tennyson-d'Eyncourt, Director of Naval Construction at the Admiralty. For secrecy, by December 1915 the name was changed to "the D.N.C.'s Committee" to disguise its purpose. Formation The committee was formed at Churchill's instruction in February 1915, in part from ideas by Colonel Ernest Swinton, who was then employed as a war correspondent for HM government, and by Maurice Hankey, Secretary of the Committee for Imperial Defence, who wrote Churchill a missive on 26 December 1914. Churchill on 5 January 1915 disclosed the Committee notion to Prime Minister H. H. Asquith ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Admiralty
The Admiralty was a Departments of the Government of the United Kingdom, department of the Government of the United Kingdom that was responsible for the command of the Royal Navy. Historically, its titular head was the Lord High Admiral of the United Kingdom, Lord High Admiral – one of the Great Officers of State. For much of its history, from the early Admiralty in the 18th century, 18th century until its abolition, the role of the Lord High Admiral was almost invariably put "in commission" and exercised by the Lords Commissioner of the Admiralty, who sat on the governing Board of Admiralty, rather than by a single person. The Admiralty was replaced by the Admiralty Board (United Kingdom), Admiralty Board in 1964, as part of the reforms that created the Ministry of Defence (United Kingdom), Ministry of Defence and its Navy Department (Ministry of Defence), Navy Department (later Navy Command (Ministry of Defence), Navy Command). Before the Acts of Union 1707, the Office of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Naval Air Service
The Royal Naval Air Service (RNAS) was the air arm of the Royal Navy, under the direction of the Admiralty (United Kingdom), 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 the Second World War. History Background On 21 July 1908 Captain Reginald Bacon, who was a member of the Aerial Navigation Sub-Committee, submitted to the First Sea Lord John Fisher, 1st Baron Fisher, Sir John Fisher that a rigid airship based on the Imperial Germany, German Zeppelin be designed and constructed by the firm of Vickers. After much discussion on the Committee of Imperial Defence the suggestion was approved on 7 May 1909. Though Bacon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oxford Dictionary Of National Biography
The ''Dictionary of National Biography'' (''DNB'') is a standard work of reference on notable figures from History of the British Isles, British history, published since 1885. The updated ''Oxford Dictionary of National Biography'' (''ODNB'') was published on 23 September 2004 in 60 volumes and online, with 50,113 biographical articles covering 54,922 lives. First series Hoping to emulate national biography, biographical collections published elsewhere in Europe, such as the (1875), in 1882 the publisher George Murray Smith, George Smith (1824–1901), of Smith, Elder & Co., planned a universal dictionary that would include biographical entries on individuals from world history. He approached Leslie Stephen, then editor of the ''Cornhill Magazine'', owned by Smith, to become the editor. Stephen persuaded Smith that the work should focus only on subjects from the United Kingdom and its present and former colonies. An early working title was the ''Biographia Britannica'', the na ...

Gears
A gear or gearwheel is a rotating machine element, machine part typically used to transmit rotation, rotational motion and/or torque by means of a series of teeth that engage with compatible teeth of another gear or other part. The teeth can be integral saliences or cavities machining, machined on the part, or separate pegs inserted into it. In the latter case, the gear is usually called a cogwheel. A cog may be one of those pegsDefinition of "cog" in the ''Oxford Learner's Dictionary'' online. Accessed on 2024-07-29.Definition of "cog" in the ''Merriam-Webster Dictionary'' online.

Epicyclic Gear
An epicyclic gear train (also known as a planetary gearset) is a gear reduction assembly consisting of two gears mounted so that the center of one gear (the "planet") revolves around the center of the other (the "sun"). A carrier connects the centers of the two gears and rotates, to carry the planet gear(s) around the sun gear. The planet and sun gears mesh so that their pitch circles roll without slip. If the sun gear is held fixed, then a point on the pitch circle of the planet gear traces an epicycloid curve. An epicyclic gear train can be assembled so the planet gear rolls on the inside of the pitch circle of an outer gear ring, or ring gear, sometimes called an ''annulus gear''. Such an assembly of a planet engaging both a sun gear and a ring gear is called a planetary gear train.J. J. Uicker, G. R. Pennock and J. E.

Flat-six Engine
A flat-six engine, also known as a horizontally opposed-six, is a six-cylinder piston engine with three cylinders on each side of a central crankshaft. The most common type of flat-six engine is the boxer-six engine, where each pair of opposed cylinders moves inwards and outwards at the same time. An alternative configuration for flat engines is a 180-degree V engine, where both cylinders move to the right then the left at the same time. The advantages of the flat-six layout are good engine balance (for reduced vibration), a low center of gravity, short length (compared with an inline-six engine) and being well suited to air-cooling. The disadvantages are a large width (which can limit the maximum steering angle when used in a front-engined car), a large intake manifold being required when a central carburetor is used, and duplication of the inlet and outlet connections for water-cooled engines. The first production flat-six engine was in the 1904 '' Wilson-Pilcher 18/24 HP'' c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
