Bristol Wayfarer
The Bristol Type 170 Freighter is a British twin-engine aircraft designed and built by the Bristol Aeroplane Company as both a freighter and airliner. Its best known use was as an air ferry to carry cars and their passengers over relatively short distances. A passenger-only version was also produced, known as the Wayfarer. The Freighter was developed during the Second World War, having attracted official attention from the British Air Ministry, which sought the development of a rugged vehicle capable of carrying various cargoes, including a 3-ton truck. Various changes to the design were made to accommodate their requirements, but being completed too late to participate in the conflict, the majority of sales of the Freighter were to commercial operators. In response to customer demand, an enlarged version to maximise vehicle-carrying capacity, known as the Bristol Superfreighter, was developed. Development The Bristol Type 170 was designed as a stop-gap project to provide w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Bristol Bombay
The Bristol Bombay was a British troop transport aircraft adaptable for use as a medium bomber flown by the Royal Air Force (RAF) during the Second World War. Design and development The Bristol Bombay was built to Air Ministry Specification C.26/31 which called for a monoplane bomber-transport aircraft to replace the Vickers Valentia biplane in use in the Middle East and India. The aircraft was required to be capable of carrying 24 troops or an equivalent load of cargo as a transport, while carrying bombs and defensive guns for use as a bomber. This dual-purpose design concept was common to British pre-war designs. Other entries for the specification were the Armstrong Whitworth A.W.23 and the Handley Page HP.52.Lewis 1980, pp. 256–259. Bristol's design, the Type 130, was a high-wing cantilever monoplane of all-metal construction. Bristol's previous monoplane design, the 1927 Bagshot, had suffered from lack of torsional rigidity in the wings leading to aileron reversal.Ba ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Centre Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the balance point) is the unique point where the weighted relative position of the distributed mass sums to zero. This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for hollow or open-shaped objects, such as a horseshoe. In the case of a distri ...

Trim Tab
Trim tabs are small surfaces connected to the trailing edge of a larger control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aerodynamic forces and stabilise the boat or aircraft in a particular desired attitude without the need for the operator to constantly apply a control force. This is done by adjusting the angle of the tab relative to the larger surface. Changing the setting of a trim tab adjusts the neutral or resting position of a control surface (such as an elevator or rudder). As the desired position of a control surface changes (corresponding mainly to different speeds), an adjustable trim tab will allow the operator to reduce the manual force required to maintain that position—to zero, if used correctly. Thus the trim tab acts as a servo tab. Because the center of pressure of the trim tab is farther away from the axis of rotation of the control surface than the center of pressure of the control surface, the ...

Bristol Hercules
The Bristol Hercules is a 14-cylinder two-row radial aircraft engine designed by Sir Roy Fedden and produced by the Bristol Engine Company starting in 1939. It was the most numerous of their single sleeve valve ( Burt-McCollum, or Argyll, type) designs, powering many aircraft in the mid-World War II timeframe. The Hercules powered a number of aircraft types, including Bristol's own Beaufighter heavy fighter design, although it was more commonly used on bombers. The Hercules also saw use in civilian designs, culminating in the 735 and 737 engines for such as the Handley Page Hastings C1 and C3 and Bristol Freighter. The design was also licensed for production in France by SNECMA. Design and development Shortly after the end of World War I, the Shell company, Asiatic Petroleum, commissioned Harry Ricardo to investigate problems of fuel and engines. His book was published in 1923 as “The Internal Combustion Engine”. Ricardo postulated that the days of the poppet valve were ...

British Far East Command
The Far East Command was a British military command which had 2 distinct periods. These were firstly, 18 November 1940 – 7 January 1942 succeeded by the American-British-Dutch-Australian Command ( ABDACOM), and secondly, 1963–1971 succeeded by Australia, New Zealand, and United Kingdom Force ( ANZUK Force) 1940–1942 The British had two commands with responsibilities for possessions in the Far East. GHQ India under General Sir Archibald Wavell the Commander-in-Chief, India and the Far East Command under Air Marshal Robert Brooke-Popham and from 23 December 1941 by Lieutenant-General Sir Henry Royds Pownall. The C-in-C Far East Command was responsible directly to the Chiefs of Staff for the operational control and general direction of training of all British land and air forces in Malaya, Burma, and Hong Kong, and for the co-ordination of plans for the defence of those territories. But the CinC exercised no command or control over any naval forces. It was intended that C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South-East Asian Theatre Of World War II
The South-East Asian Theatre of World War II consisted of the campaigns of the Pacific War in the Philippines, Thailand, Indonesia, Indochina, Burma, India, Malaya and Singapore between 1941 to 1945. Japan attacked British and American territories with near-simultaneous offensives against Southeast Asia and the Central Pacific on 7/8 December 1941. Action in this theatre ended when Japan announced an intent to surrender on 15 August 1945. The formal surrender of Japan ceremony took place on 2 September 1945. Outbreak of hostilities Conflict in this theatre began when the Empire of Japan invaded French Indochina in September 1940 and rose to a new level following the Attack on Pearl Harbor, and simultaneous attacks on Hong Kong, the Philippines, Thailand, Singapore and Malaya on 7 and 8 December 1941. The main landing at Singora (now Songkhla) on the east side of the Isthmus of Kra preceded the bombing of Pearl Harbor by several hours. Although Japan declared war on th ...
