Miles Hawcon
The Miles M.6 Hawcon was a 1930s British experimental monoplane designed by Miles Aircraft Limited. The ''Hawcon'' name comes from a combination of ''Hawk'' and ''Falcon''. Design and development The M.6 Hawcon was a one-off experimental monoplane designed for thick-wing research by the Royal Aircraft Establishment. The Hawcon combined parts from both the Hawk and Falcon and was powered by a 200 hp (149 kW) de Havilland Gipsy Six piston engine. Operational history The aircraft, serial number ''K5925'', was used for thick-wing research by the Royal Aircraft Establishment. It had four interchangeable wings of different thickness. The aim was to investigate the performance penalties of thicker wings, which had structural advantages (lower weight for the same strength) and provided space for fuel etc. The four wings, labelled A to D had root thickness to chord ratios of 0.15, 0.20, 0.25 and 0.30. The trials showed that the thickness had little effect on maximum speed: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Frederick George Miles
Frederick George Miles (22 March 1903 – 15 August 1976) was a British aircraft designer and manufacturer who designed numerous light civil and military aircraft and a range of prototypes. The name "Miles" is associated with two distinct companies that Miles was involved in and is also attached to many non-aviation products such as the Biro pen, photocopiers and book binding machinery. Throughout his life, he was known as "Miles" and never by his first name, even to his own family, although Don Brown refers to him as "F.G.", presumably to distinguish him from his brother George. Early life Miles was born on 22 March 1903 in Worthing Sussex, the oldest of four sons of Frederick Gaston Miles, a laundry proprietor (Star Model Laundry, Portslade), and his wife Esther. Miles's father is noted in the 1901 census as being a 25-year-old laundry warehouseman but by the time of the next census in 1911, he is described as being the proprietor of the laundry, a business which continued into ...

Royal Aircraft Establishment
The Royal Aircraft Establishment (RAE) was a British research establishment, known by several different names during its history, that eventually came under the aegis of the Ministry of Defence (United Kingdom), UK Ministry of Defence (MoD), before finally losing its identity in mergers with other institutions. The first site was at Farnborough Airfield ("RAE Farnborough") in Hampshire to which was added a second site RAE Bedford (Bedfordshire) in 1946. In 1988 it was renamed the Royal Aerospace Establishment (RAE) before merging with other research entities to become part of the new Defence Research Agency in 1991. History In 1904–1906 the Army Balloon Factory, which was part of the Army School of Ballooning, under the command of Colonel James Templer (balloon aviator), James Templer, relocated from Aldershot to the edge of Farnborough Common in order to have enough space to inflate the new "dirigible balloon" or airship which was then under construction.Walker, P; Early Avi ...

United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which included Wales, annexed in 1542) and the Kingdom of Scotland in 170 ...

Miles Hawk
The Miles M.2 Hawk was a twin-seat light monoplane designed and produced by the British aircraft manufacturer Miles Aircraft Limited during the 1930s. It is the first of the company's aircraft to attain quantity production. The Hawk's development started in 1932 following a conversation between designer F.G. Miles and Charles Powys, the latter offering Miles hangar space at Woodley Aerodrome to build his proposed affordable twin-seat monoplane. The aircraft was designed by Miles and his wife, while construction of the prototype was mostly performed by the carpenter Harry Hull. On 29 March 1933, the prototype performed its maiden flight. The aircraft quickly proving its performance to be roughly 50 percent greater than biplane contemporaries. Within 15 months, 47 Hawks had been sold to various domestic customers. An advanced derivative, the Miles Hawk Major, was also quickly developed, alongside several specialised versions of the original aircraft. Amongst other uses, the Ha ...

Miles Falcon
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Havilland Gipsy Six
The de Havilland Gipsy Six is a British six-cylinder, air-cooled, inverted inline piston engine developed by the de Havilland Engine Company for aircraft use in the 1930s. It was based on the cylinders of the four-cylinder Gipsy Major and went on to spawn a whole series of similar aero engines that were still in common use until the 1980s. The engines were of particular note for their exceptionally low cross-sectional area, a drag-reducing feature which made them ideal for the many racing aircraft of that period. In 1934, the basic bronze-headed Gipsy Six, rated at 185 horsepower (138 kW) at 2,100 rpm was modified for use in the DH.88 Comet air racer as the Gipsy Six "R" which produced 223 horsepower (166 kW) at 2,400 rpm for takeoff. Many Gipsy Six engines remain in service powering vintage aircraft types today. Design and development The De Havilland Engine Company company had hoped to produce a version of the basic engine capable of utilising a hydraulicall ...

Mach Number
Mach number (M or Ma) (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Moravian physicist and philosopher Ernst Mach. : \mathrm = \frac, where: : is the local Mach number, : is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and : is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number. The local spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1930s British Experimental Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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.
