Richard Pearse
Richard William Pearse (3 December 1877 – 29 July 1953) was a New Zealand farmer and inventor who performed pioneering aviation experiments. Witnesses interviewed many years afterwards describe observing Pearse flying and landing a powered heavier-than-air machine on 31 March 1903, nine months before the Wright brothers flew. Ambiguous statements made by Pearse himself make it difficult to date the aviation experiments with certainty. In a newspaper interview in 1909, with respect to inventing a flying machine, he said "I did not attempt anything practical with the idea until 1904". Biographer Gordon Ogilvie credits Pearse with "several far-sighted concepts: a monoplane configuration, wing flaps and rear elevator, tricycle undercarriage with steerable nosewheel, and a propeller with variable-pitch blades." Pearse largely ended his early flying experiments about 1911 but pioneered novel aircraft and aero-engine invention from 1933 with the development of his "private plane ...

Four-stroke Engine
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing a partial vacuum (negative pressure) in the cylinder through its downward motion. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are closed during this stage. #Combustion: Also known as power or ignition. This is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single- And Double-acting Cylinders
In mechanical engineering, the cylinders of reciprocating engines are often classified by whether they are single- or double-acting, depending on how the working fluid acts on the piston. Single-acting A single-acting cylinder in a reciprocating engine is a cylinder in which the working fluid acts on one side of the piston only. A single-acting cylinder relies on the load, springs, other cylinders, or the momentum of a flywheel, to push the piston back in the other direction. Single-acting cylinders are found in most kinds of reciprocating engine. They are almost universal in internal combustion engines (e.g. petrol and diesel engines) and are also used in many external combustion engines such as Stirling engines and some steam engines. They are also found in pumps and hydraulic rams. Double-acting A double-acting cylinder is a cylinder in which the working fluid acts alternately on both sides of the piston. In order to connect the piston in a double-acting cylinder to an ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flat Engine
A flat engine is a piston engine where the cylinders are located on either side of a central crankshaft. Flat engines are also known as horizontally opposed engines, however this is distinct from the less common opposed-piston engine design, whereby each cylinder has two pistons sharing a central combustion chamber. The most common configuration of flat engines is the boxer engine configuration, in which the pistons of each opposed pair of cylinders move inwards and outwards at the same time. The other configuration is effectively a V engine with a 180-degree angle between the cylinder banks: in this configuration each pair of cylinders shares a single crankpin, so that as one piston moves inward, the other moves outward. The first flat engine (Benz Contramotor) was built in 1897 by Karl Benz. Flat engines have been used in aviation, motorcycle and automobile applications. They are now less common in cars than straight engines (for engines with fewer than six cylinders) a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flat-twin Engine
A flat-twin engine is a two-cylinder internal combustion engine with the cylinders on opposite sides of the crankshaft. The most common type of flat-twin engine is the boxer-twin engine, where both pistons move inwards and outwards at the same time. The flat-twin design was patented by Karl Benz in 1896 and the first production flat-twin engine was used in the ''Lanchester 8 hp Phaeton'' car released in 1900. The flat-twin engine was used in several other cars since, however a more common usage is in motorcycles; early models oriented the cylinders in line with the frame, however later models switched to the cylinders being perpendicular to the frame to provide even cooling across both cylinders. Flat-twin engines were also used in several aircraft up until the 1930s and in various stationary applications from the 1930s to the 1960s. The Australian lawnmower manufacturer Victa also produced a flat-twin engine push mower from August 1975 to 1980 dubbed the ‘Twin 500’, and lat ...

George Bolt
George Bruce Bolt (24 May 1893 – 27 July 1963) was a pioneering New Zealand aviator. Biography Bolt was born in Dunedin in 1893. He formed the Canterbury Aero Club in 1910, helping to make and fly gliders on the Cashmere Hills. He used these to take aerial photographs in 1912. In 1916 Bolt was hired by pioneer pilot Vivian Walsh as a mechanic at the Walsh Brothers Flying School at Kohimarama. He learnt to fly the brothers' Curtiss flying boats and the machines of their own design, including the Walsh brothers Type D, as well as the two Boeing and Westervelt floatplanes which were the first machines made by that company. In 1919 he flew New Zealand's first air mail and established an altitude record of .Rendel, David (1975) ''Civil Aviation in New Zealand: An Illustrated History''. Wellington. A.H. & A.W. Reed. In 1921 he flew from Auckland to Wellington in 5 hours and 16 minutes with stops at Kawhia and Wanganui with Leo Walsh as passenger. He was a Royal New Zeal ...

Second Boer War
The Second Boer War (, , 11 October 189931 May 1902), also known as the Boer War, Transvaal War, Anglo–Boer War, or South African War, was a conflict fought between the British Empire and the two Boer republics (the South African Republic and Orange Free State) over Britain's influence in Southern Africa. The Witwatersrand Gold Rush caused a large influx of "Uitlander, foreigners" (''Uitlanders'') to the South African Republic (SAR), mostly British from the Cape Colony. As they, for fear of a hostile takeover of the SAR, were permitted to vote only after 14 years of residence, they protested to the British authorities in the Cape. Negotiations failed at the botched Bloemfontein Conference in June 1899. The conflict broke out in October after the British government decided to send 10,000 troops to South Africa. With a delay, this provoked a Boer and British ultimatum, and subsequent Boer Irregular military, irregulars and militia attacks on British colonial settlements in Natal ...
