Parnall
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] |
Parnall Pixie
The Parnall Pixie was a low powered British single-seat monoplane light aircraft originally designed to compete in the Lympne, UK trials for motor-gliders in 1923, where it was flown successfully by Norman Macmillan. It had two sets of wings, one for cross-country flights and the other for speed; it later appeared as a biplane which could be converted into a monoplane. Design and development Though only three Parnall Pixies were built, they appeared with a remarkable variety of wings; a normal span monoplane (Pixie I); a short span monoplane (Pixie II); a biplane readily convertible to a monoplane (Pixie IIIA); and a non-convertible monoplane version of the latter, with a greater span than the Pixie I. The first Pixie was designed to compete in the Lympne Light Aeroplane Trials of 1923, organised by the Royal Aero Club for what they described as single-seat motor-gliders. The intention was to develop economical private aviation, so the engine size was limited to 750 cc with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Kingdom Of Great Britain And Ireland
The United Kingdom of Great Britain and Ireland was a sovereign state in the British Isles that existed between 1801 and 1922, when it included all of Ireland. It was established by the Acts of Union 1800, which merged the Kingdom of Great Britain and the Kingdom of Ireland into a unified state. The establishment of the Irish Free State in 1922 led to the remainder later being renamed the United Kingdom of Great Britain and Northern Ireland in 1927. The United Kingdom, having financed the European coalition that defeated France during the Napoleonic Wars, developed a large Royal Navy that enabled the British Empire to become the foremost world power for the next century. For nearly a century from the final defeat of Napoleon following the Battle of Waterloo to the outbreak of World War I, Britain was almost continuously at peace with Great Powers. The most notable exception was the Crimean War with the Russian Empire, in which actual hostilities were relatively limited. How ...

Aircraft Carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not successfully landed on a carrier. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triplane
A triplane is a fixed-wing aircraft equipped with three vertically stacked wing planes. Tailplanes and canard foreplanes are not normally included in this count, although they occasionally are. Design principles The triplane arrangement may be compared with the biplane in a number of ways. A triplane arrangement has a narrower wing chord than a biplane of similar span and area. This gives each wing-plane a slender appearance with higher aspect ratio, making it more efficient and giving increased lift. This potentially offers a faster rate of climb and tighter turning radius, both of which are important in a fighter. The Sopwith Triplane was a successful example, having the same wing span as the equivalent biplane, the Sopwith Pup. Alternatively, a triplane has reduced span compared to a biplane of given wing area and aspect ratio, leading to a more compact and lightweight structure. This potentially offers better maneuverability for a fighter, and higher load-capacity wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parnall Possum
The Parnall Possum was an experimental triplane, with a single, central engine driving wing-mounted propellers via shafts and gears. Two of these British aircraft were built in the mid-1920s. Design and development The Parnall Possum was one of few large aircraft having its engine in its fuselage and the propellers on its wings. The concept arose immediately after World War I, when the British & Colonial Aeroplane Co. (later Bristol), began thinking about large transport aircraft powered by steam turbines mounted in an "engine room" in the fuselage and driving wing-mounted propellers. They intended to develop the idea using their large Bristol Braemar triplane bomber, initially modified to be powered by four 230 hp (172 kW) Siddeley Pumas and called, in anticipation of steam power the Tramp. They obtained Air Ministry support for this project, the Ministry appreciating the extra safety of an aircraft whose engines could be serviced in flight. The Ministry also issu ...

Fairey Flycatcher
The Fairey Flycatcher was a British single-seat biplane carrier-borne fighter aircraft made by Fairey Aviation Company which served from 1923 to 1934. It was produced with a conventional undercarriage for carrier use, although this could be exchanged for floats for catapult use aboard capital ships. Design and development The Flycatcher was designed to meet the requirements of Specification N6/22 for a carrier and floatplane fighter to replace the Gloster Nightjar, powered by either the Armstrong Siddeley Jaguar or the Bristol Jupiter radial engines. Both Fairey and Parnall submitted designs to meet this specification, with Fairey producing the Flycatcher, and Parnall the Parnall Plover.Taylor 1974, p. 113. The first of three prototype Flycatchers made its maiden flight on 28 November 1922, powered by a Jaguar II engine,Thetford 1978, p. 119. although it was later fitted with a Jupiter IV.Taylor 1974, p. 114. Small orders were placed for both the Flycatcher (for nine aircraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parnall Plover
The Parnall Plover was a British single-seat naval fighter aircraft of the 1920s. Designed and built by George Parnall & Co. for use on Royal Navy aircraft carriers, it was ordered into small-scale production but after extensive evaluation, the Fairey Flycatcher was preferred for large-scale service. Development and design The Parnall Plover was designed by Harold Bolas, chief designer of the reformed George Parnall & Co. to meet the requirements of the British Air Ministry Specification 6/22 for a single-seat fighter aircraft. The successful aircraft was to replace the Nieuport Nightjar and be powered by a Bristol Jupiter or Armstrong Siddeley Jaguar engine capable of being operated from aircraft carriers or as a floatplane. The Plover was a single-bay biplane of wood-and-fabric construction, fitted with full-span flaps and could be fitted with a conventional wheeled undercarriage or floats (with wheels protruding through the bottom of the floats). The first prototype flew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibious Aircraft
An amphibious aircraft or amphibian is an aircraft (typically fixed-wing) that can take off and land on both solid ground and water, though amphibious helicopters do exist as well. Fixed-wing amphibious aircraft are seaplanes ( flying boats and floatplanes) which are equipped with retractable wheels, at the expense of extra weight and complexity, plus diminished range and fuel economy compared to planes designed specifically for land-only or water-only operation. Some amphibians are fitted with reinforced keels which act as skis, allowing them to land on snow or ice with their wheels up. Design Floatplanes often have floats that are interchangeable with wheeled landing gear (thereby producing a conventional land-based aircraft). However, in cases where this is not practical, amphibious floatplanes, such as the amphibious version of the DHC Otter, incorporate retractable wheels within their floats. Many amphibian aircraft are of the flying boat type. These aircraft, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Experimental Aircraft
An experimental aircraft is an aircraft intended for testing new aerospace technologies and design concepts. The term ''research aircraft'' or ''testbed aircraft'', by contrast, generally denotes aircraft modified to perform scientific studies, such as weather research or geophysical surveying, similar to a research vessel. United States The term "experimental aircraft" also has specific legal meaning in Australia, the United States and some other countries; usually used to refer to aircraft flown with an experimental certificate. In the United States, this also includes most homebuilt aircraft, many of which are based on conventional designs and hence are experimental only in name because of certain restrictions in operation.

Parnall Puffin
The Parnall Puffin was an experimental amphibious fighter-reconnaissance biplane produced in the United Kingdom just after World War I. It had several unusual features, principally a single central float and an inverted vertical stabilizer and rudder, and showed promise, but at that time no new aircraft were being ordered in numbers for the RAF and only the three Puffins of the initial order were built. Design and development The Parnall Puffin was a two-seat fighter-reconnaissance aircraft built just after World War I. Like the Fairey Pintail, it was designed to meet RAF Specification XXI, issued in May 1919 for an experimental amphibious aircraft that could operate from land, carrier decks or the sea. In many regards, the Puffin was a conventional single-engined biplane of its day, but it had two unusual features: a single, central float (the first British aircraft with this seaplane configuration) and a vertical stabilizer and rudder mounted below the fuselage. The unde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Aeroplane Company
The Bristol Aeroplane Company, originally the British and Colonial Aeroplane Company, was both one of the first and one of the most important British aviation companies, designing and manufacturing both airframes and aircraft engines. Notable aircraft produced by the company include the 'Boxkite', the Bristol Fighter, the Bulldog, the Blenheim, the Beaufighter, and the Britannia, and much of the preliminary work which led to Concorde was carried out by the company. In 1956 its major operations were split into Bristol Aircraft and Bristol Aero Engines. In 1959, Bristol Aircraft merged with several major British aircraft companies to form the British Aircraft Corporation (BAC) and Bristol Aero Engines merged with Armstrong Siddeley to form Bristol Siddeley. BAC went on to become a founding component of the nationalised British Aerospace, now BAE Systems. Bristol Siddeley was purchased by Rolls-Royce in 1966, who continued to develop and market Bristol-designed engines. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
