De Havilland Highclere
The de Havilland DH.54 Highclere was a single-engined 15-passenger biplane airliner designed to replace the DH.34. Its development ended when Imperial Airways decided to use only multi-engined types. Development The DH.54 Highclere was designed to Air Ministry specification 40/22 for a larger version of the very successful DH.34 and the two aircraft had much in common, both in construction and general layout. Compared with the DH.34, the Highclere's passenger complement increased from nine to twelve, its all-up weight by 56% and its wing area by 70%. They were both single-engined two-bay biplanes with fabric-covered wooden wings and with wooden-framed fuselages covered with thin plywood. Size apart, the wings of the Highclere differed in having no stagger, no upper wing dihedral and in having a larger inter-wing gap, the upper wing now attached to the fuselage by cabane struts rather than directly to the upper fuselage. In response to criticism of the DH.34's high landing s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

De Havilland
The de Havilland Aircraft Company Limited () 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 subsidiary, inc ...

Imperial Airways
Imperial Airways was the early British commercial long-range airline, operating from 1924 to 1939 and principally serving the British Empire routes to South Africa, India, Australia and the Far East, including Malaya and Hong Kong. Passengers were typically businessmen or colonial administrators, and most flights carried about 20 passengers or less. Accidents were frequent: in the first six years, 32 people died in seven incidents. Imperial Airways never achieved the levels of technological innovation of its competitors and was merged into the British Overseas Airways Corporation (BOAC) in 1939. BOAC in turn merged with the British European Airways (BEA) in 1974 to form British Airways. Background The establishment of Imperial Airways occurred in the context of facilitating overseas settlement by making travel to and from the colonies quicker, and that flight would also speed up colonial government and trade that was until then dependent upon ships. The launch of the airline ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Air Ministry Specifications
This is a partial list of the British Air Ministry (AM) specifications for aircraft. A specification stemmed from an Operational Requirement, abbreviated "OR", describing what the aircraft would be used for. This in turn led to the specification itself, e.g. a two-engined fighter with four machine guns. So for example, OR.40 for a heavy bomber led to Specification B.12/36. Aircraft manufacturers would be invited to present design proposals to the ministry, following which prototypes of one or more of the proposals might be ordered for evaluation. On very rare occasions, a manufacturer would design and build an aircraft using their own money as a "private venture" (PV). This would then be offered to the ministry for evaluation. If the aircraft generated interest in the ministry or RAF due to performance or some other combination of features then the ministry might well issue a specification based on the private venture aircraft. The system of producing aircraft to a specification ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cabane Strut
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of strut, which act in compression or tension as the need arises, and/or wires, which act only in tension. In general, bracing allows a stronger, lighter structure than one which is unbraced, but external bracing in particular adds drag which slows down the aircraft and raises considerably more design issues than internal bracing. Another disadvantage of bracing wires is that they require routine checking and adjustment, or rigging, even when located internally. During the early years of aviation, bracing was a universal feature of all forms of aeroplane, including the monoplanes and biplanes which were then equally common. Today, bracing in the form of lift struts is still used for some light commercial designs where a high wing and light weight are more impo ...

Hubert Broad
Captain Hubert Standford Broad, MBE, AFC (1897–1975) was a British First World War aviator and noted test pilot. Early life Born at Aston Lodge, Watford, Hertfordshire on 18 May 1897, the son of Thomas and Amelia Broad (''née'' Coles), his father was a solicitor; he was educated at St. Lawrence College in Ramsgate, Kent. RNAS aviator Broad learned to fly in 1915 at the Hall School of Flying at Hendon. Flying a single-engined Caudron he received Pilot Certificate No. 2,044, after which he joined the Royal Naval Air Service at Eastchurch. After training he was posted to operations with No. 3 Squadron RNAS based at Dunkirk, France flying the Sopwith Pup. Broad was wounded in the neck during one World War I mission escorting bombers and returned to England to become an Instructor whilst he recuperated. For his second operational tour Broad was seconded to No. 46 Squadron of the Royal Flying Corps flying the Sopwith Camel. At the end of the Great War, Broad became an in ...

RAF Martlesham Heath
Royal Air Force Martlesham Heath or more simply RAF Martlesham Heath is a former Royal Air Force station located southwest of Woodbridge, Suffolk, England. It was active between 1917 and 1963, and played an important role in the development of Airborne Interception radar. History RFC/RAF prewar use Martlesham Heath was first used as a Royal Flying Corps airfield during the First World War. In 1917 it became home to the Aeroplane Experimental Unit, RFC which moved from Upavon with the site named as the Aeroplane Experimental Station which became the Aeroplane Experimental Establishment (Home) in 1920 which became the Aeroplane and Armament Experimental Establishment (A&AEE) in 1924. The A&AEE carried the evaluation and testing of many of the aircraft types and much of the armament and other equipment that would later be used during the Second World War. No. 22 Squadron RAF and No. 15 Squadron RAF were present during the 1920s. No. 64 arrived in the 1930s. RAF Fighter Command ...

RAE Farnborough
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, Macdona ...

Croydon Airport
Croydon Airport (former ICAO code: EGCR) was the UK's only international airport during the interwar period. Located in Croydon, South London, England, it opened in 1920, built in a Neoclassical style, and was developed as Britain's main airport, handling more cargo, mail, and passengers than any other UK airport at the time. Innovations at the site included the world's first air traffic control and the first airport terminal. During World War II the airport was named RAF Croydon as its role changed to that of a fighter airfield during the Battle of Britain; and in 1943 RAF Transport Command was founded at the site, which used the airport to transport thousands of troops into and out of Europe. After the Second World War, its role returned to civil aviation, but the role of London's primary international airport passed to London Heathrow Airport. Croydon Airport closed in 1959. It had been known under eight different names while it was active. In 1978, the terminal buildin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
