Parnall Parasol
The Parnall Parasol was an Experimental aircraft, experimental parasol winged aircraft design to measure the aerodynamic forces on wings in flight. Two were built and flown in the early 1930s in the UK. Design and development There have always been problems in getting an understanding of full-scale aircraft behavior from wind tunnel data. Most of these problems arise because small scale models in atmospheric pressure tunnels operate at much lower Reynolds numbers than real aircraft, making the data difficult to scale up. In the late 1920s there was only one tunnel big enough to take full size aircraft propellers, and one which by running at high pressure could reach realistic Reynolds numbers with aircraft models; both of these were recent and in the USA. It is therefore not surprising that some aircraft were designed specifically to undertake aerodynamic studies of particular components. In the UK, the Bristol Type 92, Bristol "Laboratory" was built to study the drag of dif ... [...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 Wikimedia project, 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.

Oleo (shock Absorber)
An oleo strut is a pneumatic air–oil hydraulic shock absorber used on the landing gear of most large aircraft and many smaller ones. This design cushions the impacts of landing and damps out vertical oscillations. It is undesirable for an airplane to bounce on landing as it could lead to a loss of control, and the landing gear should not add to this tendency. A steel coil spring stores impact energy from landing and then releases it, while an oleo strut instead absorbs this energy, reducing bounce. As the strut compresses, the spring rate increases dramatically because the air is being compressed. The viscosity of the oil dampens the rebound movement. History and applications The original design for the oleo-pneumatic shock-absorbing strut was patented by British manufacturing conglomerate Vickers Armstrong during 1915. It had been derived from the recuperative gear design of the Vickers gun, controlling recoil by forcing oil through precisely sized orifices. Vickers' oleo st ...

Parasol-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of 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 can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Parnall Aircraft
Parnall was a British aircraft manufacturer that evolved from a wood-working company before the First World War to a significant designer of military and civil aircraft into the 1940s. It was based in the west of England and was originally known as George Parnall & Co. Ltd. History In 1916, the Bristol based Parnall & Sons shopfitters started to manufacture aircraft at the Colliseum Works at Park Row in Bristol. During the First World War, the skilled staff were moved to sites around the city and in neighbouring South Gloucestershire producing planes to their own designs and, under contract, those of other companies. In 1919, the aircraft business was split from the parent company Parnall & Sons as George Parnall and Company. In the 1920s, aircraft manufacture was centralised at a factory in Yate close to an airfield used by the Royal Flying Corps. In the 1930s, gun turrets for bomber aircraft were produced. The site was a strategic target for Luftwaffe bombing and during 1941 ... [...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.

Avro
AVRO, short for Algemene Vereniging Radio Omroep ("General Association of Radio Broadcasting"), was a Dutch public broadcasting association operating within the framework of the Nederlandse Publieke Omroep system. It was the first public broadcaster in the Netherlands. In 2014 AVRO merged with fellow broadcaster TROS to form AVROTROS. History On 8 July 1923, Hilversumsche Draadlooze Omroep was launched by the Nederlandsche Seintoestellen Fabriek (in English: Dutch Transmitter Factory) under supervision of Willem Vogt. On 21 July 1923, it provided the very first regular radio broadcast in the Netherlands. In 1927 it changed its name into Algemeene Nederlandsche Radio Omroep (ANRO), followed soon by a merger with Nederlandsche Omroep Vereeniging (NOV). On 28 December 1927, the two merged broadcasters continued as Algemeene Vereeniging Radio Omroep (A.V.R.O., in English: "General Association of Radio Broadcasting"). In 1938, AVRO sponsored what was the strongest chess tourna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 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, 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 Aviation at Farnborough, Volume I: Balloons, Kites and Airships, Macdo ...

Parnall Elf
The Parnall Elf is a British two seat light touring aircraft of the 1920s. Built by Parnall, George Parnall & Co. the Elf was the last aircraft designed by Harold Bolas before he left the company to go to the United States. Design and development The Parnall Elf was designed by Harold Bolas, chief designer of the reformed George Parnall & Co. The type made its public debut at Olympia, London, Olympia in July 1929.Ogilvy, 1989. The Elf was a biplane of wood and fabric construction with staggered wings set well forward on the fuselage as a feature to assist crew escape in an emergency. The wings were unusually braced with 'vee' interplane struts which dispensed with any flying wires and could be folded for ease of hangarage. The main fuel tank was fitted in the fuselage, while a pump raised the fuel to a small tank in the wing centre section where it was then fed to the engine by gravity. An Elf placed fifth in the 1930 King's Cup Air Race out of a field of 88 entrants. The purch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
