Pearse Monoplane
Richard William Pearse (3 December 187729 July 1953) was a New Zealand farmer and inventor who performed pioneering aviation experiments. Witnesses interviewed many years afterward 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 on in novel aircraft and aero-engine invention from 1933 with the development of his "private plane ...

Alfred Pearse
Alfred Pearse (20 May 1855 – 1933), also known as A Patriot, was an English artist, author, campaigner and inventor. Pearse, born at St Pancras, London, was a fourth generation artist and son of celebrated decorative artist Joseph Salter Pearse (1822–1896) and Loveday Colbron (1825–1895). He studied at West London School of Art and gained numerous prizes for drawing. As special artist and correspondent to The Sphere (newspaper), ''The Sphere'', he was assigned to the Duke and Duchess of Cornwall and York's 1901 tour of New Zealand. Pearse designed posters campaigning for women's suffrage. He drew a weekly cartoon for ''Votes for Women'' from 1909, and was also regularly published in ''The Illustrated London News'', ''Boy's Own Paper'' and ''Punch''. With Laurence Housman, he set up the Suffrage Atelier. Pearse produced various artworks, cartoons and propaganda related to British efforts in World War I. From 11 September 1918 to March 1919, he held an honorary captain's c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tires
A tire (American English) or tyre (British English) is a ring-shaped component that surrounds a Rim (wheel), wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide Traction (engineering), traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, which also provide a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint, called a contact patch, that is designed to match the weight of the vehicle with the bearing strength of the surface that it rolls over by providing a bearing pressure that will not deform the surface excessively. The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric, and wire, along with carbon black and other chemical compounds. They consist of a tire tread, tread and a body. The tread provides Traction (engineering), traction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tricycle
A tricycle, sometimes abbreviated to trike, is a human-powered (or gasoline or electric motor powered or assisted, or gravity powered) three-wheeled vehicle. Some tricycles, such as cycle rickshaws (for passenger transport) and freight trikes, are used for commercial purposes, especially in the developing world, particularly Africa and Asia. In the West, adult-sized tricycles are used primarily for recreation, shopping, and exercise. Tricycles are favoured by children and senior adults for their apparent stability versus a bicycle; however a conventional trike has poor dynamic lateral stability, and the rider must take care when cornering to avoid tipping the trike over. Unconventional designs such as recumbents have a lower centre of gravity so require less care. History A three-wheeled wheelchair was built in 1655 or 1680 by a disabled German man, Stephan Farffler, who wanted to be able to maintain his mobility. A watch-maker, Farffler created a vehicle that was powered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samuel Langley
Samuel Pierpont Langley (August 22, 1834 – February 27, 1906) was an American aviation pioneer, astronomer and physicist who invented the bolometer. He was the third secretary of the Smithsonian Institution and a professor of astronomy at the University of Pittsburgh, where he was the director of the Allegheny Observatory. Life Langley was born in Roxbury, Boston, on August 23, 1834. Langley attended Boston Latin School and graduated from English High School of Boston, after which he became an assistant in the Harvard College Observatory. He then moved to a job at the United States Naval Academy, ostensibly as a professor of mathematics. However, he was actually sent there to restore the Academy's small observatory. In 1867, he became the director of the Allegheny Observatory and a professor of astronomy at the University of Pittsburgh (then known as the Western University of Pennsylvania), a post he kept until 1891 even while he became the third Secretary of the Smithso ...

Carburetor
A carburetor (also spelled carburettor) is a device used by an internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the venturi tube in the main metering circuit, however various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, however carburetors are still used by some small engines (e.g. lawnmowers, generators and concrete mixers) and motorcycles. Diesel engines have always used fuel injection instead of carburetors. Etymology The name "carburetor" is derived from the verb ''carburet'', which means "to combine with carbon," or in particular, "to enrich a gas by combining it with carbon or hydrocarbons." Thus a carburetor mixes intake air with hydrocarbon-based fuel, such as petrol or autogas (LPG). The name is spelled "carburetor" in American English ...

Mica
Micas ( ) are a group of silicate minerals whose outstanding physical characteristic is that individual mica crystals can easily be split into extremely thin elastic plates. This characteristic is described as perfect basal cleavage. Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock. It is particularly prominent in many granites, pegmatites, and schists, and "books" (large individual crystals) of mica several feet across have been found in some pegmatites. Micas are used in products such as drywalls, paints, fillers, especially in parts for automobiles, roofing and shingles, as well as in electronics. The mineral is used in cosmetics and food to add "shimmer" or "frost." Properties and structure The mica group is composed of 37 phyllosilicate minerals. All crystallize in the monoclinic system, with a tendency towards pseudohexagonal crystals, and are similar in structure but vary in chemical composition. Micas are ...

Electrode
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). Electrodes are essential parts of batteries that can consist of a variety of materials depending on the type of battery. The electrophore, invented by Johan Wilcke, was an early version of an electrode used to study static electricity. Anode and cathode in electrochemical cells Electrodes are an essential part of any battery. The first electrochemical battery made was devised by Alessandro Volta and was aptly named the Voltaic cell. This battery consisted of a stack of copper and zinc electrodes separated by brine-soaked paper disks. Due to fluctuation in the voltage provided by the voltaic cell it wasn't very practical. The first practical battery was invented in 1839 and named the Daniell cell after John Frederic Daniell. Still making use of the zinc–copper electrode combination. Since then many more batteries have be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spark Plug
A spark plug (sometimes, in British English, a sparking plug, and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine. A spark plug has a metal threaded shell, electrically isolated from a central electrode by a ceramic insulator. The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto. The spark plug's metal shell is screwed into the engine's cylinder head and thus electrically grounded. The central electrode protrudes through the porcelain insulator into the combustion chamber, forming one or more spark gaps between the inner end of the central electrode and usually one or more protuberances or structures attached to the inner end of the threaded shell and designated the ''side ...

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 an RNZAF and Roya ...
