Bristol Seely
The Bristol Seely was entered into an Air Ministry competition for safe civil aeroplanes held in 1920. It was a single-engine biplane with accommodation for one passenger. After the competition, the single Seely was used as a testbed for the Bristol Jupiter engine development programme. Development The 1920 civil aeroplane competition emphasised safety in terms of a short takeoff and slow landing speed as well as useful load and economy. The rules of the competition were released in July 1919 and Bristol decided that a modification of the Tourer was their best hope. The single passenger was enclosed in a cabin immediately behind the pilot's open cockpit, with a raised roof and windows in the decking where the second seat in the Tourer had been. In addition, the fuselage was deepened by dropping the lower longerons and floor to the lower wing spar. Ahead of the pilot, the fuselage bays were built from steel rather than wood spars. The single-axle main undercarriage carried wheels ... [...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 sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource.

Siddeley Puma
The Siddeley Puma was a British aero engine developed towards the end of World War I and produced by Siddeley-Deasy. The first engines left the production lines of Siddeley-Deasy in Coventry in August 1917, production continued until December 1918. At least 4,288 of the 11,500 ordered engines were delivered, orders were cancelled following the Armistice with Germany (Compiègne), Armistice. Production was continued under the name Armstrong Siddeley Puma when the manufacturer was bought by Armstrong Whitworth and became Armstrong Siddeley. The engine was based on a previous Beardmore Halford Pullinger, B.H.P engine which was also developed as the Galloway "Adriatic." Applications *The Puma engine was used in the British World War I bomber aircraft, the Airco D.H.9. In use it proved to be highly troublesome, making the aircraft significantly inferior to the type it replaced. The engine was also installed untidily, with the cylinder heads protruding. The D.H.9, as a type, was impr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bristol Seely Rear
Bristol () is a city, ceremonial county and unitary authority in England. Situated on the River Avon, it is bordered by the ceremonial counties of Gloucestershire to the north and Somerset to the south. Bristol is the most populous city in South West England. The wider Bristol Built-up Area is the eleventh most populous urban area in the United Kingdom. Iron Age hillforts and Roman villas were built near the confluence of the rivers Frome and Avon. Around the beginning of the 11th century, the settlement was known as (Old English: 'the place at the bridge'). Bristol received a royal charter in 1155 and was historically divided between Gloucestershire and Somerset until 1373 when it became a county corporate. From the 13th to the 18th century, Bristol was among the top three English cities, after London, in tax receipts. A major port, Bristol was a starting place for early voyages of exploration to the New World. On a ship out of Bristol in 1497, John Cabot, a Venetian, b ...

Supercharger
In an internal combustion engine, a supercharger compresses the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a supercharger is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gasses. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. The first supercharged engine was built in 1878, with usage in aircraft engines beginning in the 1910s and usage in car engines beginning in the 1920s. In piston engines used by aircraft, supercharging was often used to compensate for the lower air density at high altitudes. Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and/or increase power outputs. Des ...

Leitner-Watts
The Metal Airscrew Company was formed in 1919 by Dr. Henry Charles Watts and Henry Leitner to produce hollow metal aircraft propellers with a method set out their joint patent. By 1928 the company name had changed to Metal Propellers Ltd. It remained active until at least 1930. History The Leitner-Watts propellers were amongst the earliest with a thick metal aerodynamic profile. Watts was the aerodynamicist who determined the blade profile, Leitner the engineer who translated it into metal and designed hubs for two, three and four bladed propellers. The blades were produced in the Rubery Owen factory in Darlaston, Staffordshire. Each blade side or shell was made up from three laminations of steel sheet, shaped in a press. The outer layer formed the complete shell shape and the progressively shorter, Y-shaped inner laminations strengthened the bade towards the root. The laminations were riveted or spot-welded together and the two shells welded together at their edges. To sti ... [...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 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 ...

Sopwith Antelope
The Sopwith Antelope was a British three-seat transport aircraft built after the end of the First World War. A single-engined biplane based on the Sopwith Wallaby long-range aircraft, only a single Antelope was built. Development and design In 1919, the Sopwith Aviation Company developed a three-seat transport aircraft, the Sopwith Antelope, based on its Wallaby long-range aircraft built to compete for a £10,000 prize for an England-Australia flight, which was in turn based on the Sopwith Atlantic, which had crashed during an attempt to be the first aircraft cross the Atlantic Ocean non-stop earlier that year.Jackson 1988, p.311.Robertson 1970, p.231.Robertson 1970, p.142. Like the Wallaby, the Antelope was a single-engined tractor biplane, but with a modified fuselage to accommodate the pilot and two passengers. The pilot sat in an open cockpit under the tailing edge of the wing, in front of an enclosed cabin where the two passengers sat on wicker seats facing each other, w ...

Westland Limousine
The Westland Limousine was a 1920s British single-engined four-seat light transport aircraft built by Westland Aircraft. History At the end of World War I, the prospect of an expanding aviation market led Westland Aircraft to design a light transport aircraft for three passengers. It was Westland's first commercial aeroplane and designated the Westland Limousine I. The first aircraft (initially registered ''K-126'', but quickly re-registered ''G-EAFO'') flew in July 1919. A biplane, it was powered by one Rolls-Royce Falcon III engine. The passengers were in an enclosed cabin and the pilot sat in the port rear of the four seats. His seat was higher to enable his head to be raised through the cabin roof. The second aircraft (''G-EAJL'') was designated the Limousine II and was completed in October 1919.James 1991, p.88. Both the first and second aircraft were used from September 1920 for two months on an experimental express air mail service between Croydon and Le Bourget. A t ...

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 ...

Radiator
Radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heating. The majority of radiators are constructed to function in cars, buildings, and electronics. A radiator is always a source of heat to its environment, although this may be for either the purpose of heating this environment, or for cooling the fluid or coolant supplied to it, as for automotive engine cooling and HVAC dry cooling towers. Despite the name, most radiators transfer the bulk of their heat via convection instead of thermal radiation. History The Roman hypocaust is an early example of a type of radiator for building space heating. Franz San Galli, a Prussian-born Russian businessman living in St. Petersburg, is credited with inventing the heating radiator around 1855, having received a radiator patent in 1857, but American Joseph Nason developed a primitive radiator in 1841 and received a number of U.S. patents for hot water and steam heating. ...
