Roe III Triplane
The Roe III Triplane was an early aircraft designed by the British aircraft manufacturer Avro. In configuration, it was similar to the Roe II Triplane, with a triplane tailplane and an open-top fuselage of triangular cross-section, but the Roe III was a two-seater, and featured ailerons for the first time in a Roe design. The five (some sources give three) production machines differed from the prototype in having the ailerons fitted to the middle wing (the prototype's were on the upper wing) and in being powered by a Green engine in place of the prototype's JAP. One example was sold to the Harvard Aeronautical Society, one was exported to the United States The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America.

Avro Aircraft
AVRO, short for Algemene Vereniging Radio Omroep ("General Association of Radio Broadcasting"), was a Dutch public broadcasting association operating within the framework of the Nederlandse Publieke Omroep system. It was the first public broadcaster in the Netherlands. In 2014 AVRO merged with fellow broadcaster TROS to form AVROTROS. History On 8 July 1923, Hilversumsche Draadlooze Omroep was launched by the Nederlandsche Seintoestellen Fabriek (in English: Dutch Transmitter Factory) under supervision of Willem Vogt. On 21 July 1923, it provided the very first regular radio broadcast in the Netherlands. In 1927 it changed its name into Algemeene Nederlandsche Radio Omroep (ANRO), followed soon by a merger with Nederlandsche Omroep Vereeniging (NOV). On 28 December 1927, the two merged broadcasters continued as Algemeene Vereeniging Radio Omroep (A.V.R.O., in English: "General Association of Radio Broadcasting").

1910s British Experimental Aircraft
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Roe IV Triplane
The Roe IV Triplane was an early British aircraft designed by Alliott Verdon Roe and built by A.V. Roe and Company. It was first flown in September 1910. Design and development The Roe IV Triplane resembled Roe's Type III, being a tractor configuration triplane with the lower wing of smaller span than the upper two and a triangular section wire-braced fuselage, which was uncovered behind the pilot's seat. The middle wing was mounted directly above the upper longerons, and there was a gap between the single lower longeron and the lower wing. The wings were connected by four unequally-spaced pairs of interplane struts on either side, the innermost pair on each side being just outboard of the upper longerons and the outer pair connecting only the upper pair of wings due to the shorter span of the lower wing. Although the ailerons fitted to the previous design had been satisfactory, Roe returned to wing warping for lateral control. The lifting triplane tailplanes of the earlier d ...

Roe I Triplane
The Roe I Triplane (often later referred to as the Avro Triplane) was an early aircraft designed and built by A.V. Roe which was the first all-British aircraft to fly.Jackson 1990 p.6 (Roe's previous biplane had a French engine). Background After being evicted from Brooklands, where he had worked on his first aircraft, Roe started work in July 1908 on the design of a triplane: a patent was filed for this design in January 1909,Jackson 1990 p.4 and work was started on the construction of an aircraft of this design in the stable adjoining the house of his brother, Dr Spencer Verdon Roe, in Putney in South-West London. It was then transported to the new flying ground that Roe had found on Walthamstow Marshes (then in Essex, but now within the London Borough of Waltham Forest), where he rented two railway arches under the LNER railway besides the river Lea. Design and development The Roe I Triplane was a two-bay triplane: the tailplane, with a span of also had three surfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roe I Biplane
The Roe I Biplane (often later referred to as the Avro Biplane) was the first powered aircraft to be designed, built, and flown in England. Designed in an attempt to claim a prize offered by the Brooklands Automobile Racing Club, it was designed and built by Alliott Verdon Roe, who based it on a powered model with which he had won a ''Daily Mail'' prize of £75 at Alexandra Palace in April 1907. This prize was substantially larger: the club committee was offering £2,500 for the first person to fly a circuit of their three-mile (4.8 km) race track by the end of the year. In addition the ''Daily Graphic'' was offering a £1,000 prize for a flight of more than a mile (1.6 km).Jackson 1990 p.2 The Roe biplane was built in the coachhouse of Roe's brother in Putney and transported to Brooklands for testing in September 1907. It was an unequal-span canard configuration two-bay biplane without any vertical stabilising surface or rudder and was originally powered by a 9 ...

Green C
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, while red ...

NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum camber as percentage of the chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

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'', ...
