Parnall 382
The Parnall 382 was a 1930s British single-engined monoplane trainer aircraft with two open cockpits, designed and developed by Parnall Aircraft Ltd. Design and development The Parnall 382 was designed to meet UK Air Ministry Specification T.1/37 for an 'ab initio' trainer, and was also known as the Parnall Heck III. Its competitors were the Heston T.1/37 and the Miles M.15. The Airspeed AS.36, General Aircraft GAL.32 and Percival P.20 were also proposed against specification T.1/37, but not accepted or built. None of the designs was selected for production orders; it has been suggested that the required performance could not be achieved within the constraints of the Specification. Construction was primarily wooden, with plywood-skinned spruce frames. The cantilever oleo-pneumatic fixed main undercarriage legs were faired with spats. The undercarriage, tail unit and outer wing panels were adapted from the Parnall Heck 2C. The propeller was a de Havilland fixed-pitch type. ...

Monoplane
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 wings. 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 slowe ...

General Aircraft
General Aircraft Limited was a British aircraft manufacturer from its formation in 1931 to amalgamation with Blackburn Aircraft in 1949 to become Blackburn and General. Its main products were military gliders and light transport aircraft. History On 27 February 1931, General Aircraft Limited (GAL) was formed to undertake production of aircraft using the 'monospar' wing designs of the Monospar Wing Company Ltd. Both firms were headed by Helmut J. Stieger, the Swiss inventor of the technique. GAL produced about 28 examples of the Monospar series of twin-engined light transport aircraft at Croydon Aerodrome between 1932 and 1934. In October 1934, both companies were re-capitalised by investment group British Pacific Trust, and were re-formed in a new company also named General Aircraft Limited. Also included in the new company were the assets of National Flying Services Ltd, the owner of London Air Park in Hanworth near Feltham, plus adjoining industrial premises built in 1917 ...

Air Training Corps
The Air Training Corps (ATC) is a British Youth organisations in the United Kingdom, volunteer youth organisation; aligned to, and fostering the knowledge and learning of military values, primarily focusing on military aviation. Part of the Royal Air Force Air Cadets (RAFAC), the ATC is sponsored by the Royal Air Force (RAF) and the wider Ministry of Defence (United Kingdom), Ministry of Defence (MoD). The majority of Air Training Corps staff are volunteers, though some staff are paid for full-time work; including Commandant Air Cadets, who is a RAF officer ranks, Royal Air Force officer as part of a Reservist, Full Term Reserve Service commitment. Members of the Air Training Corps are known as Air Cadets, which is often interchanged with the term 'ATC cadets'. Although many ATC cadets subsequently go on to join the Royal Air Force, or the other branches of the British Armed Forces (or have the desire to do so), the ATC is not a recruiting organisation for its parent service ...

Martlesham Heath
Martlesham Heath is a village in Suffolk, England. It is east of Ipswich, This was an ancient area of heathland and latterly the site of Martlesham Heath Airfield. A "new village" was established there in the mid-1970s and this has developed into a modern community, based on a traditional village pattern. The population is still included in that of Martlesham. The village is also part of the wider Ipswich Built-up area. History There is evidence of settlement in this area since the Bronze Age, with a number of round barrows surviving to the present. The main community of Martlesham grew up to the north-east, initially on the highest ground, where Martlesham Church is still located, then, later, centring on the point where the main London-to-Yarmouth road crosses the River Finn, a tributary to the Deben. White's 1844 directory of Suffolk describes Martlesham as "a neat village near the confluence of a rivulet with the Deben" but mentions that the parish includes "a large, s ...

Aeroplane & Armament Experimental Establishment
The Aeroplane and Armament Experimental Establishment (A&AEE) was a research facility for British military aviation from 1918 to 1992. Established at Martlesham Heath, Suffolk, the unit moved in 1939 to Boscombe Down, Wiltshire, where its work continues following privatisation as part of the Qinetiq company. History In 1917, the Experimental Aircraft Flight of the Central Flying School was transferred from Upavon, Wiltshire to a site on the heathland at Martlesham, Suffolk, and on 16 January 1917 Martlesham Heath Airfield was officially opened, as an experimental airfield. The unit was renamed the Aeroplane Experimental Unit, Royal Flying Corps. After the end of World War I the site continued to be used and was, once again, renamed as the Aeroplane and Armament Experimental Establishment of the Royal Air Force. At the outbreak of the Second World War, on 9 September, the A&AEE was removed to RAF Boscombe Down, Wiltshire, owing to the proximity of Martlesham Heath to the ...

Yate
Yate is a town and civil parish in South Gloucestershire, England. It lies just to the southwest of the Cotswolds, Cotswold Hills and is northeast of Bristol and from Bath, Somerset, Bath. Developing from a small village into a town from the 1950s onwards, the 2021 UK census, census listed Yate's parish population as 23,703. The market town of Chipping Sodbury (population 5,045) is contiguous with Yate to the east. In addition, a large southern section of the built-up area spills over into the parish of Dodington, Gloucestershire, Dodington (population 8,206), and as a result, the total population of Yate's urban area is estimated at 35,000. Location Yate is located to the northeast of Bristol, which is away by road. Yate is surrounded by a vast amount of countryside and is situated to the south-west of the Cotswolds. The A432 road, A432 is the main road through Yate and runs through the centre of the town. History The first mention of Yate is the existence of a religiou ...

De Havilland
The de Havilland Aircraft Company Limited (pronounced , ) was a British aviation manufacturer established in late 1920 by Geoffrey de Havilland at Stag Lane Aerodrome Edgware on the outskirts of North London. Operations were later moved to Hatfield in Hertfordshire. Known for its innovation, de Havilland was responsible for a number of important aircraft, including the Moth biplane which revolutionised aviation in the 1920s; the 1930s Fox Moth, a commercial light passenger aircraft; the wooden World War II Mosquito multirole aircraft; and the pioneering passenger jet airliner Comet. The de Havilland company became a member of the Hawker Siddeley group in 1960, but lost its separate identity in 1963. Later, Hawker Siddeley merged into what is eventually known today as BAE Systems, the British aerospace and defence business. The de Havilland name lives on in de Havilland Canada, which owns the rights to the name and the aircraft produced by de Havilland's former Canadian ...

Percival
Perceval (, also written Percival, Parzival, Parsifal), alternatively called Peredur (), is a figure in the legend of King Arthur, often appearing as one of the Knights of the Round Table. First mentioned by the French author Chrétien de Troyes in the tale '' Perceval, the Story of the Grail'', he is best known for being the original hero in the quest for the Grail before being replaced in later literature by Galahad. Etymology and origin The earliest reference to Perceval is found in Chrétien de Troyes's first Arthurian romance ''Erec et Enide'', where, as "Percevaus li Galois" (Percevaus of Wales), he appears in a list of Arthur's knights. In another of Chrétien's romances, '' Cligés'', Perceval is a "renowned vassal" who is defeated by the knight Cligés in a tournament. He then becomes the eponymous protagonist of Chrétien's final romance, '' Perceval, the Story of the Grail''. In the Welsh romance '' Peredur son of Efrawg'', the corresponding figure goes by th ...

Airspeed
In aviation, airspeed is the speed of an aircraft relative to the air it is flying through (which itself is usually moving relative to the ground due to wind). In contrast, the ground speed is the speed of an aircraft with respect to the surface of the Earth (whether over land or presumed-stationary water). It is difficult to measure the exact airspeed of the aircraft (true airspeed), but other measures of airspeed, such as indicated airspeed and Mach number give useful information about the capabilities and limitations of airplane performance. The common measures of airspeed are: * Indicated airspeed (IAS), what is read on an airspeed gauge connected to a pitot-static system. * Calibrated airspeed (CAS), indicated airspeed adjusted for pitot system position and installation error. * True airspeed (TAS) is the actual speed the airplane is moving through the air. When combined with aircraft direction, wind speed and direction, it can be used to calculate ground speed and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trainer (aircraft)
A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft. Civilian pilots are normally trained in a light aircraft, with two or more seats to allow for a student and instructor. Tandem and side by side The two seating configurations for trainer aircraft are: pilot and instructor side by side, or in tandem, usually with the pilot in front and the instructor behind. The side-by-side seating configuration has the advantage that the pilot and instructor can see each other's actions, allowing the pilot to learn from the instructor and the instructor to correct the student pilot. The tandem configuration has the advantage of being closer to the normal working environment th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miles M
The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a imperial unit, British imperial unit and United States customary unit of length; both are based on the older English unit of Unit of length, length equal to 5,280 Foot (unit), English feet, or 1,760 yards. The statute mile was standardised between the Commonwealth of Nations and the United States by an international yard and pound, 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, Roman mile (roughly ), such as the #Nautical, nautical mile (now exactly), the #Italian, Italian mile (roughly ), and the li (unit), Chinese mile (now exactly). The Romans divided their mile into 5,000 (), but the greater importance of furlongs in the Kingdom of England#Tudor period, Elizabethan-era England meant th ...

Heston T
Heston is a suburban area and part of the Hounslow district in the London Borough of Hounslow. The residential settlement covers a slightly smaller area than its predecessor farming village, 10.8 miles (17.4 km) west south-west of Charing Cross and adjoins the M4 motorway but has no junction with it; Heston also adjoins the Great West Road, a dual carriageway, mostly west of the "Golden Mile" headquarters section of it. Heston was, historically, in Middlesex. History The village of Heston is north of Hounslow, and has been settled since Saxon times. It is first recorded as having a priest in the 7th century, though the present Anglican parish church dates to the 14th century. A charter of Henry II gives the name as Hestune, meaning "enclosed settlement", which is justified by its location in what was the Warren of Staines, between the ancient Roman road to Bath, and the Uxbridge Road to Oxford. Another suggested etymology is Anglo-Saxon ''Hǣs-tūn'' = "brushwood farm o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
