Dunne D.8
The Dunne D.8 of 1912 was a tailless swept wing biplane, designed by J. W. Dunne to have inherent stability. One example was supplied to RAE Farnborough. License-built Burgess-Dunne models were used by the US Signal Corps and United States Navy and the short-lived Canadian Aviation Corps. It was the latter's first and only warplane. Design and development J. W. Dunne's first swept biplane wing aircraft, designed to have automatic stability, dated from his employment at the Army Balloon Factory (later RAE Farnborough) during 1906–09. After leaving Farnborough, Dunne set up a private company, the Blair Atholl Aeroplane Syndicate Ltd. Its first aircraft was the Dunne D.5. When this crashed in 1911 it was rebuilt as the first D.8. The two models shared similar wings and the same engine, but the D.8 had a single pusher propeller instead of the chain-driven pair of the D.5. Their fuselages and undercarriages were also different. The D.8 was a tailless four bay unstaggered biplane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Washout (aviation)
Washout is a characteristic of aircraft wing design which deliberately reduces the lift distribution across the span of an aircraft’s wing. The wing is designed so that the angle of incidence is greater at the wing roots and decreases across the span, becoming lowest at the wing tip. This is usually to ensure that at stall speed the wing root stalls before the wing tips, providing the aircraft with continued aileron control and some resistance to spinning. Washout may also be used to modify the spanwise lift distribution to reduce lift-induced drag. Design considerations Washout is commonly achieved by designing the wing with a slight twist, reducing the angle of incidence from root to tip, and therefore causing a lower angle of attack at the tips than at the roots. This feature is sometimes referred to as structural washout, to distinguish it from aerodynamic washout. Wingtip stall is unlikely to occur symmetrically, especially if the aircraft is maneuvering.

Royal Aero Club
The Royal Aero Club (RAeC) is the national co-ordinating body for air sport in the United Kingdom. It was founded in 1901 as the Aero Club of Great Britain, being granted the title of the "Royal Aero Club" in 1910. History The Aero Club was founded in 1901 by Frank Hedges Butler, his daughter Vera and the Hon Charles Rolls (one of the founders of Rolls-Royce), partly inspired by the Aero Club of France. It was initially concerned more with ballooning but after the demonstrations of heavier-than air flight made by the Wright Brothers in France in 1908, it embraced the aeroplane. The original club constitution declared that it was dedicated to 'the encouragement of aero auto-mobilism and ballooning as a sport.' As founded, it was primarily a London gentlemen's club, but gradually moved on to a more regulatory role. It had a clubhouse at 119 Piccadilly, which it retained until 1961.Anthony Lejeune, ''The Gentlemen's Clubs of London'' (London, 1978) p.178 The club was granted its ...

Larkhill
Larkhill is a garrison town in the civil parish of Durrington, Wiltshire, England. It lies about west of the centre of Durrington village and north of the prehistoric monument of Stonehenge. It is about north of Salisbury. The settlement has a long association with the British military and originally grew from military camps. It is now one of the main garrisons on Salisbury Plain, along with Tidworth Camp, Bulford Camp, and Waterloo Lines at Warminster. The Royal School of Artillery is at Larkhill and the Royal Artillery moved its main barracks there from Woolwich in 2008. Etymology Before the military garrison was established the area was known as Lark Hill, part of Durrington Down, owing to it being the highest point in the parish. After the first military buildings were established, it came to be known as Larkhill Camp. History Much of Larkhill lies within the Stonehenge World Heritage Site, an area rich in Neolithic and Bronze Age monuments. Several long barrows a ...

Eastchurch
Eastchurch is a village and civil parish on the Isle of Sheppey, in the English county of Kent, two miles east of Minster. The village website claims the area has "a history steeped in stories of piracy and smugglers". Aviation history Eastchurch is styled the "home of British aviation" as Eastchurch airfield saw the first controlled flight by a British pilot on British soil. The Eastchurch airfield played a significant role in the history of British aviation from 1909 when Frank McClean acquired Stonepits Farm, on the marshes across from Leysdown, converting the land into an airfield for members of the Aero Club of Great Britain. The Short Brothers, Horace, Eustace and Oswald, built aircraft at Battersea to be tested at the site; later Moore-Brabazon, A. K. Huntington, Charles S. Rolls and Cecil Grace all visited and used the flying club's services. Wilbur Wright and his brother Orville came to the Isle of Sheppey to visit the new flying grounds of the Aero Club. In 190 ...

Rotary Engine
The rotary engine is an early type of internal combustion engine, usually designed with an odd number of cylinders per row in a radial configuration. The engine's crankshaft remained stationary in operation, while the entire crankcase and its attached cylinders rotated around it as a unit. Its main application was in aviation, although it also saw use in a few early motorcycles and automobiles. This type of engine was widely used as an alternative to conventional inline engines (straight or V) during World War I and the years immediately preceding that conflict. It has been described as "a very efficient solution to the problems of power output, weight, and reliability". By the early 1920s, the inherent limitations of this type of engine had rendered it obsolete. Description Distinction between "rotary" and "radial" engines A rotary engine is essentially a standard Otto cycle engine, with cylinders arranged radially around a central crankshaft just like a conventional ra ...

Gnome Et Rhône
Gnome et Rhône was a major French aircraft engine manufacturer. Between 1914 and 1918 they produced 25,000 of their 9-cylinder Delta and Le Rhône 110 hp (81 kW) rotary designs, while another 75,000 were produced by various licensees. These engines powered the majority of aircraft in the first half of the war, both Allied designs as well as German examples produced by Motorenfabrik Oberursel. In the post-war era they started a new design series originally based on the Bristol Jupiter, but evolving into the excellent twin-row, 1,000 hp-class (750 kW) Gnome-Rhône 14K ''Mistral Major'' radial, which was likewise licensed and used around the world during World War II. They were a major supplier of engines to the German ''Luftwaffe'', producing both their own designs as well as German ones under licence. Their factories were the target of highly accurate bombing, knocking them out of the war. The company was nationalized as a part of Snecma in 1949, but ...

Green Engine Co
__NOTOC__ The Green Engine Co was a British engine company founded by Gustavus Green in Bexhill to sell engines of his design. He flourished especially as a designer of aeroplane engines during the first two decades of the 20th century. The engines were actually manufactured by the Aster Engineering Company. History The firm produced a range of water-cooled, mostly inline engines up to about 1915. Green engines powered many pioneering British aircraft, including those of A. V. Roe, Samuel Cody, and Short Brothers. They had several advanced features in common; cast steel single-piece cylinders and cylinder heads, two valves per cylinder driven by an overhead camshaft, white metal crankshaft bearings and copper and rubber-sealed water jackets. Manufacture was at the Aster Engineering Company of Wembley. When the Great War broke out, the company was known for its motorcycle engines and particularly associated with a "pannier honeycomb" radiator design.Anon, ''The Motorcycle'', ...

Short Brothers
Short Brothers plc, usually referred to as Shorts or Short, is an aerospace company based in Belfast, Northern Ireland. Shorts was founded in 1908 in London, and was the first company in the world to make production aeroplanes. It was particularly notable for its flying boat designs manufactured into the 1950s. In 1943, Shorts was nationalised and later denationalised, and in 1948 moved from its main base at Rochester, Kent to Belfast. In the 1960s, Shorts mainly produced turboprop airliners, major components for aerospace primary manufacturers, and missiles for the British Armed Forces. Shorts was primarily government-owned until being bought by Bombardier in 1989, and is today the largest manufacturing concern in Northern Ireland. In November 2020, Bombardier sold its Belfast operations to Spirit AeroSystems. The company's products include aircraft components, engine nacelles and aircraft flight control systems for its parent company Bombardier Aerospace, and for Boeing ...

Elevons
Elevons or tailerons are aircraft control surfaces that combine the functions of the elevator (used for pitch control) and the aileron (used for roll control), hence the name. They are frequently used on tailless aircraft such as flying wings. An elevon that is not part of the main wing, but instead is a separate tail surface, is a stabilator (but stabilators are also used for pitch control only, with no roll function, as on the Piper Cherokee series of aircraft). Elevons are installed on each side of the aircraft at the trailing edge of the wing. When moved in the same direction (up or down) they will cause a pitching force (nose up or nose down) to be applied to the airframe. When moved differentially, (one up, one down) they will cause a rolling force to be applied. These forces may be applied simultaneously by appropriate positioning of the elevons e.g. one wing's elevons completely down and the other wing's elevons partly down. An aircraft with elevons is controlled as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
