British Military Aircraft Designation Systems
British military aircraft designations are used to refer to aircraft types and variants operated by the armed forces of the United Kingdom. Since the end of the First World War, aircraft types in British military service have generally been known by a service name (e.g. "Spitfire"), with individual variants recognised by mark numbers often in combination with a letter to indicate the role. This is in contrast to identification systems used in countries such as the United States, where an aircraft type is primarily identified by an alphanumeric designation. The British military aircraft designations (e.g. "Spitfire Mark V" or "Hercules C3") should not be confused with the serial number used to identify individual aircraft (e.g. "XR220"), nor with U.S. aircraft designations (e.g. "C-5", "C-17", "MQ-9") or manufacturer's designations (e.g. "Sikorsky S-58", "Jaguar B", " WS-61", " AW139", " WAH-64"), though Mark numbers were used to indicate aircraft built for other nations e.g. ...

Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger h ...

Rolls-Royce Ltd
Rolls-Royce was a British luxury car and later an aero-engine manufacturing business established in 1904 in Manchester by the partnership of Charles Rolls and Henry Royce. Building on Royce's good reputation established with his cranes, they quickly developed a reputation for superior engineering by manufacturing the "best car in the world". The business was incorporated as Rolls-Royce Limited in 1906, and a new factory in Derby was opened in 1908. The First World War brought the company into manufacturing aero-engines. Joint development of jet engines began in 1940, and they entered production. Rolls-Royce has built an enduring reputation for development and manufacture of engines for defence and civil aircraft. In the late 1960s, Rolls-Royce was adversely affected by the mismanaged development of its advanced RB211 jet engine and consequent cost over-runs, though it ultimately proved a great success. In 1971, the owners were obliged to liquidate their business. The useful ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawker Aircraft
Hawker Aircraft Limited was a British aircraft manufacturer that was responsible for some of the most famous products in British aviation history. History Hawker had its roots in the aftermath of the First World War, which resulted in the bankruptcy of the Sopwith Aviation Company. Sopwith test pilot Harry Hawker and three others, including Thomas Sopwith, bought the assets of Sopwith and formed H.G. Hawker Engineering in 1920. In 1933, the company was renamed Hawker Aircraft Limited, and it took advantage of the Great Depression and a strong financial position to purchase the Gloster Aircraft Company in 1934. The next year, it merged with the engine and automotive company Armstrong Siddeley and its subsidiary, Armstrong Whitworth Aircraft, to form Hawker Siddeley Aircraft. This group also encompassed A. V. Roe and Company (Avro). The company continued to produce designs under the "Hawker" name as part of Hawker Siddeley Aircraft, which from 1955 was a division of Hawk ...

Geodesic Airframe
A geodetic airframe is a type of construction for the airframes of aircraft developed by British aeronautical engineer Barnes Wallis in the 1930s (who sometimes spelt it "geodesic"). Earlier, it was used by Prof. Schütte for the Schütte Lanz Airship SL 1 in 1909. It makes use of a space frame formed from a spirally crossing basket-weave of load-bearing members.Buttler, p.93 The principle is that two geodesic arcs can be drawn to intersect on a curving surface (the fuselage) in a manner that the torsional load on each cancels out that on the other.Buttler, p.94 Early examples The "diagonal rider" structural element was used by Joshua Humphreys in the first US Navy sail frigates in 1794. Diagonal riders are viewable in the interior hull structure of the preserved USS ''Constitution'' on display in Boston Harbor. The structure was a pioneering example of placing "non- orthogonal" structural components within an otherwise conventional structure for its time. The "diagona ...

Vickers-Armstrongs
Vickers-Armstrongs Limited was a British engineering conglomerate formed by the merger of the assets of Vickers Limited and Sir W G Armstrong Whitworth & Company in 1927. The majority of the company was nationalised in the 1960s and 1970s, with the remainder being divested as Vickers plc in 1977. History Vickers merged with the Tyneside-based engineering company Armstrong Whitworth, founded by William Armstrong, to become Vickers-Armstrongs. Armstrong Whitworth and Vickers had developed along similar lines, expanding into various military sectors and produced a whole suite of military products. Armstrong Whitworth were notable for their artillery manufacture at Elswick and shipbuilding at a yard at High Walker on the River Tyne. 1929 saw the merger of the acquired railway business with those of Cammell Laird to form Metropolitan Cammell Carriage and Wagon (MCCW); Metro Cammell. In 1935, before rearmament began, Vickers-Armstrongs was the third-largest manufacturing emp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alliteration
Alliteration is the conspicuous repetition of initial consonant sounds of nearby words in a phrase, often used as a literary device. A familiar example is "Peter Piper picked a peck of pickled peppers". Alliteration is used poetically in various languages around the world, including Arabic, Irish, German, Mongolian, Hungarian, American Sign Language, Somali, Finnish, Icelandic. Historical use The word ''alliteration'' comes from the Latin word ''littera'', meaning "letter of the alphabet". It was first coined in a Latin dialogue by the Italian humanist Giovanni Pontano in the 15th century. Alliteration is used in the alliterative verse of Old English, Old Norse, Old High German, Old Saxon, and Old Irish. It was an important ingredient of the Sanskrit shlokas. Alliteration was used in Old English given names. This is evidenced by the unbroken series of 9th century kings of Wessex named Æthelwulf, Æthelbald, Æthelberht, and Æthelred. These were followed in the 10th c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Admiralty (United Kingdom)
The Admiralty was a department of the Government of the United Kingdom responsible for the command of the Royal Navy until 1964, historically under its titular head, the Lord High Admiral – one of the Great Officers of State. For much of its history, from the early 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 in 1964, as part of the reforms that created the Ministry of Defence and its Navy Department (later Navy Command). Before the Acts of Union 1707, the Office of the Admiralty and Marine Affairs administered the Royal Navy of the Kingdom of England, which merged with the Royal Scots Navy and the absorbed the responsibilities of the Lord High Admiral of the Kingdom of Scotland with the unification of the Kingdom of Great Br ...

Air Ministry
The Air Ministry was a department of the Government of the United Kingdom with the responsibility of managing the affairs of the Royal Air Force, that existed from 1918 to 1964. It was under the political authority of the Secretary of State for Air. Organisations before the Air Ministry The Air Committee On 13 April 1912, less than two weeks after the creation of the Royal Flying Corps (which initially consisted of both a naval and a military wing), an Air Committee was established to act as an intermediary between the Admiralty and the War Office in matters relating to aviation. The new Air Committee was composed of representatives of the two war ministries, and although it could make recommendations, it lacked executive authority. The recommendations of the Air Committee had to be ratified by the Admiralty Board and the Imperial General Staff and, in consequence, the Committee was not particularly effective. The increasing separation of army and naval aviation from 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Sycamore
The Bristol Type 171 Sycamore was an early helicopter developed and built by the helicopter division of the Bristol Aeroplane Company. The name refers to the seeds of the sycamore tree, ''Acer pseudoplatanus'', which fall with a rotating motion. It has the distinction of being the first British helicopter to receive a certificate of airworthiness, as well as being the first British-designed helicopter to be introduced by and to serve with the Royal Air Force (RAF). Typically capable of seating up to three passengers, the type was often used as a transport for both passengers and cargo alike. In RAF service, the Sycamore was normally used in the search and rescue and casualty evacuation roles. The type proved the value of rotorcraft to easily traverse inhospitable or otherwise inaccessible terrain; the Sycamore made valuable contributions to British military activities during the Malayan Emergency, the Cyprus Emergency, and the Aden Emergency, in addition to other operations. ...

Battle Of Hastings
The Battle of Hastings nrf, Batâle dé Hastings was fought on 14 October 1066 between the Norman-French army of William, the Duke of Normandy, and an English army under the Anglo-Saxon King Harold Godwinson, beginning the Norman Conquest of England. It took place approximately northwest of Hastings, close to the present-day town of Battle, East Sussex, and was a decisive Norman victory. The background to the battle was the death of the childless King Edward the Confessor in January 1066, which set up a succession struggle between several claimants to his throne. Harold was crowned king shortly after Edward's death, but faced invasions by William, his own brother Tostig, and the Norwegian King Harald Hardrada (Harold III of Norway). Hardrada and Tostig defeated a hastily gathered army of Englishmen at the Battle of Fulford on 20 September 1066, and were in turn defeated by Harold at the Battle of Stamford Bridge five days later. The deaths of Tostig and Hardrada at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fairey Battle
The Fairey Battle is a British single-engine light bomber that was designed and manufactured by the Fairey Aviation Company. It was developed during the mid-1930s for the Royal Air Force (RAF) as a monoplane successor to the Hawker Hart and Hind biplanes. The Battle was powered by the same high-performance Rolls-Royce Merlin piston engine that powered various contemporary British fighters such as the Hawker Hurricane and Supermarine Spitfire. As the Battle, with its three-man crew and bomb load, was much heavier than the fighters, it was therefore much slower. Though a great improvement over the aircraft that preceded it, its relatively slow speed, limited range and inadequate defensive armament of only two .303 (7.7 mm) machine guns left it highly vulnerable to enemy fighters and anti-aircraft fire.Ethell 1995, p. 177. The Fairey Battle was used on operations early in the Second World War. During the " Phoney War" the type achieved the distinction of scoring the firs ...
