Miles M.71 Merchantman
The Miles Merchantman was a scaled-up and four-engined development of the Miles Aerovan light freighter. It flew in 1947 but the design was abandoned when Miles Aircraft was taken over by Handley Page in 1948. Design and development The Miles M.71 Merchantman was intended to follow the successful Aerovan freighter as a larger aircraft built along similar lines. Miles aimed to provide a simple, sturdy high-wing monoplane with an easily accessible and configurable cargo or passenger space. This was achieved, as in the Aerovan by mounting the tail unit on a boom from the fuselage top, making access via the rear of the fuselage straightforward. Intended for greater loads the Merchantman was bigger, heavier and more powerful than its predecessor: its span was larger by a factor of 1.33, all up weight by 2.2 and power by 3.2. Unlike the Aerovan the Merchantman was intended to be a largely all-metal-framed aircraft, though the first prototype and only example built had wooden ta ...

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 ...

Society Of British Aerospace Companies
The Society of British Aerospace Companies, formerly Society of British Aircraft Constructors, known as SBAC, was the UK's national trade association representing companies supplying civil air transport, aerospace defence, homeland security and space. As of October 2009 SBAC merged with the Defence Manufacturers Association and the Association of Police and Public Security Suppliers to form the ADS Group. The SBAC organises the Farnborough Airshow. Representation With its regional partners, SBAC represents over 2,600 companies, assisting them in developing new business globally, facilitating innovation and competitiveness and providing regulatory services in technical standards and accreditation. Inside the organisation is the British Aviation Group and the UK Space Agency. History Formation On 29 March 1915 a number of British aircraft manufacturers and industrialists met to arrange a standards body and production pooling system known as the Society of British Aircraft Con ...

High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External Bracing (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

1940s British Cargo Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 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. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

Miles Aircraft
Miles was the name used between 1943 and 1947 to market the aircraft of British engineer Frederick George Miles, who, with his wife – aviator and draughtswoman Maxine "Blossom" Miles (née Forbes-Robertson) – and his brother George Herbert Miles, designed numerous light civil and military aircraft and a range of curious prototypes. History Phillips and Powis A company was founded in 1928 by Charles Powis and Jack Phillips as Phillips & Powis Aircraft (Reading) Ltd. In 1929 they opened Woodley Aerodrome, near the town of Reading, Berkshire. In 1936, Rolls-Royce bought into the company. Although aircraft were produced under the Miles name, it was not until 1943 that the firm became Miles Aircraft Limited when Rolls-Royce's interests were bought out. The company needed to increase production of the Miles Messenger and to do so it took over a former linen mill in Banbridge, County Down, Northern Ireland for the production of components of the aircraft.

Miles M
The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a British imperial unit and United States customary unit of distance; both are based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. The statute mile was standardised between the British Commonwealth and the United States by an international agreement in 1959, when it was formally redefined with respect to SI units as exactly . With qualifiers, ''mile'' is also used to describe or translate a wide range of units derived from or roughly equivalent to the Roman mile, such as the nautical mile (now exactly), the Italian mile (roughly ), and the Chinese mile (now exactly). The Romans divided their mile into 5,000 Roman feet but the greater importance of furlongs in Elizabethan-era England meant that the statute mile was made equivalent to or in 1593. This form of the mile then spread across the British Empire, some successor states of which conti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radlett
Radlett is a village in Hertfordshire, England, between Elstree and St Albans on Watling Street, with a population of 8,042. It is in the council district of Hertsmere in the south of the county, and is covered by two wards; Aldenham East and Aldenham West. It is located inside the M25 motorway. Locality Radlett lies in the valley of Tykes Water, a stream that runs north from Aldenham Reservoir to the River Colne. Now entirely surrounded by the Metropolitan Green Belt, it is subject to significant 'infill' development and there is pressure to relax the Green Belt restrictions. Radlett is located 14 miles (22.5 km) north west of the centre of London. It is one of the wealthiest places in Britain and the second most expensive town to buy a house outside London. The town contains many substantial detached houses with large gardens. In the older centre there are also a few streets with Victorian semi detached and terraced houses.

Adverse Yaw
Adverse yaw is the natural and undesirable tendency for an aircraft to yaw in the opposite direction of a roll. It is caused by the difference in lift and drag of each wing. The effect can be greatly minimized with ailerons deliberately designed to create drag when deflected upward and/or mechanisms which automatically apply some amount of coordinated rudder. As the major causes of adverse yaw vary with lift, any fixed-ratio mechanism will fail to fully solve the problem across all flight conditions and thus any manually operated aircraft will require some amount of rudder input from the pilot in order to maintain coordinated flight. History Adverse yaw was first experienced by the Wright brothers when they were unable to perform controlled turns in their 1901 glider which had no vertical control surface. Orville Wright later described the glider's lack of directional control. Causes Adverse yaw is a secondary effect of the inclination of the lift vectors on the wing due to its ...
