Miles M.25 Martinet
The Miles M.25 Martinet was a target tug aircraft of the Royal Air Force (RAF) and Fleet Air Arm (FAA) that was in service during the Second World War. It was the first British aircraft to be designed specifically for target towing. Work on the Martinet was started in response to the RAF's shortage of obsolete frontline aircraft for target towing duties. It was intentionally designed with as much commonality as was feasible to existing production aircraft, being a derivative of Miles' prolific Master trainer. The first prototype Martinet conducted its maiden flight on 24 April 1942, with quantity production commencing immediately thereafter. A total of 1,724 Martinets were produced, of which the majority were operated either by the RAF or FAA, although a minority were also used by overseas and civilian operators. The Martinet was also developed into a relatively secretive aircraft in response to Specification Q.10/43, which called for a radio-controlled target drone. ...

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".

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 191 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miles Master II
The Miles M.9 Master was a British two-seat monoplane advanced trainer designed and built by aviation company Miles Aircraft Ltd. It was inducted in large numbers into both the Royal Air Force (RAF) and Fleet Air Arm (FAA) during the Second World War. The Master can trace its origins back to the earlier M.9 Kestrel demonstrator aircraft. Following the failure of the rival de Havilland Don as a satisfactory trainer aircraft, the RAF ordered 500 ''M9A Master'' advanced trainers to meet its needs. Once in service, it provided a fast, strong and fully aerobatic aircraft that functioned as an excellent introduction to the high performance British fighter aircraft of the day: the Spitfire and Hurricane. Throughout its production life, thousands of aircraft and various variants of the Master were produced, the latter being largely influenced by engine availability. Numerous Masters were modified to enable their use as glider tows. The Master also served as the basis for the Mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glider (aircraft)
A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude (normally a sailplane relies on rising air to maintain altitude) with some being powerful enough to take off by self-launch. There are a wide variety of types differing in the construction of their wings, aerodynamic efficiency, location of the pilot, controls and intended purpose. Most exploit meteorological phenomena to maintain or gain height. Gliders are principally used for the air sports of gliding, hang gliding and paragliding. However some spacecraft have been designed to descend as gliders and in the past military gliders have been used in warfare. Some simple and familiar types of glider are toys such as paper planes and balsa wood gliders. Etym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boulton Paul Balliol
The Boulton Paul Balliol and Sea Balliol are monoplane advanced trainer aircraft designed and produced by the British aircraft manufacturer Boulton Paul Aircraft. On 17 May 1948, it became the world's first single-engined turboprop aircraft to fly. The Balliol was operated primarily by both the Royal Air Force (RAF) and the Royal Navy Fleet Air Arm (FAA). Developed during the late 1940s, the Balliol was designed to fulfil Air Ministry Specification T.7/45, replacing the wartime North American Harvard trainer. Unlike previous trainer aircraft, which were powered by piston engines, it was specified for the aircraft to use newly developed turboprop propulsion instead. On 30 May 1947, the Balliol performed its maiden flight; the first preproduction aircraft would fly during the following year. Production examples were powered by the Rolls-Royce Merlin engine, while various prototypes and pre-production aircraft featured alternative powerplants such as the Rolls-Royce Dart and Armst ...

Avro Athena
The Avro 701 Athena is a British advanced trainer aircraft built by Avro in the late 1940s. It was designed to replace the North American Harvard in the Royal Air Force, but was bought only in small numbers, the competing Boulton Paul Balliol being preferred. Design and development The Athena was designed to meet the requirements of Air Ministry Specification T.7/45 for a three-seat advanced trainer powered by a turboprop engine for the RAF. The Athena was an all-metal low-winged monoplane, with a side-by-side cockpit. The Air Ministry rethought its requirements in 1947 and replaced the original specification with Specification T.14/47, which specified the use of a Rolls-Royce Merlin 35 piston engine, large stocks of which were held in store. Despite the change in specification, the first three prototypes were of the turboprop-powered Athena T.1, the first of which, powered by an Armstrong Siddeley Mamba engine, flew on 12 June 1948 at Woodford Aerodrome. The Merlin-powere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turboprop
A turboprop is a turbine engine that drives an aircraft propeller. A turboprop consists of an intake, reduction gearbox, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel is then added to the compressed air in the combustor, where the fuel-air mixture then combusts. The hot combustion gases expand through the turbine stages, generating power at the point of exhaust. Some of the power generated by the turbine is used to drive the compressor and electric generator. The gases are then exhausted from the turbine. In contrast to a turbojet or turbofan, the engine's exhaust gases do not provide enough energy to create significant thrust, since almost all of the engine's power is used to drive the propeller. Technological aspects Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtained by extracting additional power (beyond that necessary to drive the compressor) from turbine ex ...

Farnborough Airshow
The Farnborough Airshow, officially the Farnborough International Airshow, is a trade exhibition for the aerospace and defence industries, where civilian and military aircraft are demonstrated to potential customers and investors. Since its first show in 1948, Farnborough has seen the debut of many famous planes, including the Vickers VC10, Concorde, the Eurofighter, the Airbus A380, and the Lockheed Martin F-35 Lightning II. At the 1958 show, the RAF's Black Arrows executed a 22-plane formation loop, setting a world record. The international trade show is put together every two years by FIL Farnborough International Ltd. and runs for five days. Until 2020, the show ran for a full week with trade visitors attending on the first five days and the weekend reserved for the general public. Programming takes place at the Farnborough Airport, which lies roughly 50 kilometres south-west of London. Status The Farnborough International Airshow is the second-largest show of its kind afte ...

Official Secrets Act 1911
The Official Secrets Act 1911 (1 & 2 Geo 5 c 28) is an Act of the Parliament of the United Kingdom. It replaces the Official Secrets Act 1889. The Act was introduced in response to public alarm at reports of wide-scale espionage, some of them fomented by popular novels and plays that dramatized the threat, supposedly from Germany, at a time of a rapid naval expansion. Its provisions were extensive, with heavy penalties for any reporting or sketching of military, naval or air defence installations, or the harbouring of people suspected of gathering such intelligence. It has been amended several times; most importantly the "catch-all" provisions contained in section 2 of the Act were repealed and replaced by the Official Secrets Act 1989. The Act applies in the United Kingdom, the Isle of Man, the Channel Islands, and in overseas crown territories and colonies. It also applies to British subjects anywhere else in the world. In the Republic of Ireland, the Act was repealed by sect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classified Information
Classified information is material that a government body deems to be sensitive information that must be protected. Access is restricted by law or regulation to particular groups of people with the necessary security clearance and need to know, and mishandling of the material can incur criminal penalties. A formal security clearance is required to view or handle classified material. The clearance process requires a satisfactory background investigation. Documents and other information must be properly marked "by the author" with one of several (hierarchical) levels of sensitivity—e.g. restricted, confidential, secret, and top secret. The choice of level is based on an impact assessment; governments have their own criteria, including how to determine the classification of an information asset and rules on how to protect information classified at each level. This process often includes security clearances for personnel handling the information. Some corporations and non-governm ...

Thomas Rose (RAF Officer)
Thomas Rose (27 January 1895 – 20 June 1968) was a British flying ace in World War I, credited with 11 victories. Better known as "Tommy" Rose, he also won the King's Cup Air Race in 1935 and from 1939 to 1945 was Chief Test Pilot with Phillips & Powis Aircraft Ltd. – renamed Miles Aircraft Ltd. in 1943. World War I Rose joined the Royal Flying Corps in 1917 and was posted to No. 64 Squadron later that year, flying DH.5s. The squadron was involved in the Battle of Cambrai in a ground-strafing role. It subsequently re-equipped with SE5as, which led to greater involvement in aerial combat. He was awarded the DFC in November 1918, having become a deputy flight commander. Later military service Following the end of the war, Rose became a flight commander with No. 43 Squadron, RAF, serving from 1925 to 1927. Civil aviation career After leaving the RAF with the rank of flight lieutenant, Rose worked in aviation first taking a job at Brooklands in charge of Britain's fi ...

Flight Lieutenant
Flight lieutenant is a junior commissioned rank in air forces that use the Royal Air Force (RAF) system of ranks, especially in Commonwealth countries. It has a NATO rank code of OF-2. Flight lieutenant is abbreviated as Flt Lt in the Indian Air Force (IAF) and RAF, and as FLTLT in the Pakistan Air Force (PAF), Royal Australian Air Force (RAAF) and Royal New Zealand Air Force (RNZAF) and has sometimes also been abbreviated as F/L in many services; it has never been correctly abbreviated as "lieutenant". A flight lieutenant ranks above flying officer and below a squadron leader and is sometimes used as an English language translation of a similar rank in non-English-speaking countries. The rank originated in the Royal Naval Air Service (RNAS) in 1914. It fell into abeyance when the RNAS merged with the Royal Flying Corps during the First World War but was revived in 1919 in the post-war RAF. An RAF flight lieutenant is the equivalent of a lieutenant in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
