12 Phillips, Horatio Frederick
SUBJECT AREA: Aerospace[br]b. 2 February 1845 London, Englandd. 15 July 1926 Hampshire, England[br]English aerodynamicist whose cambered two-surface wing sections provided the foundations for aerofoil design.[br]At the age of 19, Phillips developed an interest in flight and constructed models with lightweight engines. He spent a large amount of time and money over many years, carrying out practical research into the science of aerodynamics. In the early 1880s he built a wind tunnel with a working section of 15 in. by 10 in. (38 cm by 25 cm). Air was sucked through the working section by an adaptation of the steam injector used in boilers and invented by Henry Giffard, the airship pioneer. Phillips tested aerofoils based on the cross-section of bird's wings, with a greater curvature on the upper surface than the lower. He measured the lift and drag and showed that the major component of lift came from suction on the upper surface, rather than pressure on the lower. He took out patents for his aerofoil sections in 1884 and 1891. In addition to his wind-tunnel test, Phillips tested his wing sections on a whirling arm, as used earlier by Cayley, Wenham and Lilienthal. After a series of tests using an arm of 15 ft (4.57 m) radius, Phillips built a massive whirling arm driven by a steam engine. His test pieces were mounted on the end of the arm, which had a radius of 50 ft (15.24 m), giving them a linear speed of 70 mph (113 km/h). By 1893 Phillips was ready to put his theories to a more practical test, so he built a large model aircraft driven by a steam engine and tethered to run round a circular track. It had a wing span of 19 ft (5.79 m), but it had fifty wings, one above the other. These wings were only 10 in. (25 cm) wide and mounted in a frame, so it looked rather like a Venetian blind. At 40 mph (64 km/h) it lifted off the track. In 1904 Phillips built a full-size multi-wing aeroplane with twenty wings which just lifted off the ground but did not fly. He built another multi-wing machine in 1907, this time with four Venetian blind' frames in tandem, giving it two hundred wings! Phillips made a short flight of almost 500 ft (152 m) which could be claimed to be the first powered aeroplane flight in England by an Englishman. He retired from flying at the age of 62.[br]Bibliography1900, "Mechanical flight and matters relating thereto", Engineering (reprint).1891–3, "On the sustentation of weight by mechanical flight", Aeronautical Society of Great Britain 23rd Report.Further ReadingJ.Laurence Pritchard, 1957, "The dawn of aerodynamics", Journal of the Royal Aeronautical Society (March) (good descriptions of Phillips's early work and his wind tunnel).J.E.Hodgson, 1924, The History of Aeronautics in Great Britain, London.F.W.Brearey, 1891–3, "Remarks on experiments made by Horatio Phillips", Aeronautical Society of Great Britain 23rd Report.JDSBiographical history of technology > Phillips, Horatio Frederick

14 Lanchester, Frederick William
[br]b. 28 October 1868 Lewisham, London, Englandd. 8 March 1946 Birmingham, England[br]English designer and builder of the first all-British motor car.[br]The fourth of eight children of an architect, he spent his childhood in Hove and attended a private preparatory school, from where, aged 14, he went to the Hartley Institution (the forerunner of Southampton University). He was then granted a scholarship to the Royal College of Science, South Kensington, and also studied practical engineering at Finsbury Technical College, London. He worked first for a draughtsman and pseudo-patent agent, and was then appointed Assistant Works Manager of the Forward Gas Engine Company of Birmingham, with sixty men and a salary of £1 per week. He was then aged 21. His younger brother, George, was apprenticed to the same company. In 1889 and 1890 he invented a pendulum governor and an engine starter which earned him royalties. He built a flat-bottomed river craft with a stern paddle-wheel and a vertical single-cylinder engine with a wick carburettor of his own design. From 1892 he performed a number of garden experiments on model gliders relating to problems of lift and drag, which led him to postulate vortices from the wingtips trailing behind, much of his work lying behind the theory of modern aerodynamics. The need to develop a light engine for aircraft led him to car design.In February 1896 his first experimental car took the road. It had a torsionally rigid chassis, a perfectly balanced and almost noiseless engine, dynamically stable steering, epicyclic gear for low speed and reverse with direct drive for high speed. It turned out to be underpowered and was therefore redesigned. Two years later an 8 hp, two-cylinder flat twin appeared which retained the principle of balancing by reverse rotation, had new Lanchester valve-gear and a new method of ignition based on a magneto generator. For the first time a worm and wheel replaced chain-drive or bevel-gear transmission. Lanchester also designed the machinery to make it. The car was capable of about 18 mph (29 km/h): future cars of his travelled at twice that speed. From 1899 to 1904 cars were produced for sale by the Lanchester Engine Company, which was formed in 1898. The company had to make every component except the tyres. Lanchester gave up the managership but remained as Chief Designer, and he remained in this post until 1914.In 1907–8 his two-volume treatise Aerial Flight was published; it included consideration of skin friction, boundary-layer theory and the theory of stability. In 1909 he was appointed to the Government's Committee for Aeronautics and also became a consultant to the Daimler Company. At the age of 51 he married Dorothea Cooper. He remained a consultant to Daimler and worked also for Wolseley and Beardmore until 1929 when he started Lanchester Laboratories, working on sound reproduction. He also wrote books on relativity and on the theory of dimensions.[br]Principal Honours and DistinctionsFRS.Bibliographybht=1907–8, Aerial Flight, 2 vols.Further ReadingP.W.Kingsford, 1966, F.W.Lanchester, Automobile Engineer.E.G.Semler (ed.), 1966, The Great Masters.

19 Cayley, Sir George
SUBJECT AREA: Aerospace[br]b. 27 December 1773 Scarborough, Englandd. 15 December 1857 Brompton Hall, Yorkshire, England[br]English pioneer who laid down the basic principles of the aeroplane in 1799 and built a manned glider in 1853.[br]Cayley was born into a well-to-do Yorkshire family living at Brompton Hall. He was encouraged to study mathematics, navigation and mechanics, particularly by his mother. In 1792 he succeeded to the baronetcy and took over the daunting task of revitalizing the run-down family estate.The first aeronautical device made by Cayley was a copy of the toy helicopter invented by the Frenchmen Launoy and Bienvenu in 1784. Cayley's version, made in 1796, convinced him that a machine could "rise in the air by mechanical means", as he later wrote. He studied the aerodynamics of flight and broke away from the unsuccessful ornithopters of his predecessors. In 1799 he scratched two sketches on a silver disc: one side of the disc showed the aerodynamic force on a wing resolved into lift and drag, and on the other side he illustrated his idea for a fixed-wing aeroplane; this disc is preserved in the Science Museum in London. In 1804 he tested a small wing on the end of a whirling arm to measure its lifting power. This led to the world's first model glider, which consisted of a simple kite (the wing) mounted on a pole with an adjustable cruciform tail. A full-size glider followed in 1809 and this flew successfully unmanned. By 1809 Cayley had also investigated the lifting properties of cambered wings and produced a low-drag aerofoil section. His aim was to produce a powered aeroplane, but no suitable engines were available. Steam-engines were too heavy, but he experimented with a gunpowder motor and invented the hot-air engine in 1807. He published details of some of his aeronautical researches in 1809–10 and in 1816 he wrote a paper on airships. Then for a period of some twenty-five years he was so busy with other activities that he largely neglected his aeronautical researches. It was not until 1843, at the age of 70, that he really had time to pursue his quest for flight. The Mechanics' Magazine of 8 April 1843 published drawings of "Sir George Cayley's Aerial Carriage", which consisted of a helicopter design with four circular lifting rotors—which could be adjusted to become wings—and two pusher propellers. In 1849 he built a full-size triplane glider which lifted a boy off the ground for a brief hop. Then in 1852 he proposed a monoplane glider which could be launched from a balloon. Late in 1853 Cayley built his "new flyer", another monoplane glider, which carried his coachman as a reluctant passenger across a dale at Brompton, Cayley became involved in public affairs and was MP for Scarborough in 1832. He also took a leading part in local scientific activities and was co-founder of the British Association for the Advancement of Science in 1831 and of the Regent Street Polytechnic Institution in 1838.[br]BibliographyCayley wrote a number of articles and papers, the most significant being "On aerial navigation", Nicholson's Journal of Natural Philosophy (November 1809—March 1810) (published in three numbers); and two further papers with the same title in Philosophical Magazine (1816 and 1817) (both describe semi-rigid airships).Further ReadingL.Pritchard, 1961, Sir George Cayley, London (the standard work on the life of Cayley).C.H.Gibbs-Smith, 1962, Sir George Cayley's Aeronautics 1796–1855, London (covers his aeronautical achievements in more detail).—1974, "Sir George Cayley, father of aerial navigation (1773–1857)", Aeronautical Journal (Royal Aeronautical Society) (April) (an updating paper).JDS -
20 Cousteau, Jacques-Yves
SUBJECT AREA: Ports and shipping[br]b. 11 June 1910 Saint-André-de-Cubzac, France[br]French marine explorer who invented the aqualung.[br]He was the son of a country lawyer who became legal advisor and travelling companion to certain rich Americans. At an early age Cousteau acquired a love of travel, of the sea and of cinematography: he made his first film at the age of 13. After an interrupted education he nevertheless passed the difficult entrance examination to the Ecole Navale in Brest, but his naval career was cut short in 1936 by injuries received in a serious motor accident. For his long recuperation he was drafted to Toulon. There he met Philippe Tailliez, a fellow naval officer, and Frédéric Dumas, a champion spearfisher, with whom he formed a long association and began to develop his underwater swimming and photography. He apparently took little part in the Second World War, but under cover he applied his photographic skills to espionage, for which he was awarded the Légion d'honneur after the war.Cousteau sought greater freedom of movement underwater and, with Emile Gagnan, who worked in the laboratory of Air Liquide, he began experimenting to improve portable underwater breathing apparatus. As a result, in 1943 they invented the aqualung. Its simple design and robust construction provided a reliable and low-cost unit and revolutionized scientific and recreational diving. Gagnan shunned publicity, but Cousteau revelled in the new freedom to explore and photograph underwater and exploited the publicity potential to the full.The Undersea Research Group was set up by the French Navy in 1944 and, based in Toulon, it provided Cousteau with the Opportunity to develop underwater exploration and filming techniques and equipment. Its first aims were minesweeping and exploration, but in 1948 Cousteau pioneered an extension to marine archaeology. In 1950 he raised the funds to acquire a surplus US-built minesweeper, which he fitted out to further his quest for exploration and adventure and named Calypso. Cousteau also sought and achieved public acclaim with the publication in 1953 of The Silent World, an account of his submarine observations, illustrated by his own brilliant photography. The book was an immediate success and was translated into twenty-two languages. In 1955 Calypso sailed through the Red Sea and the western Indian Ocean, and the outcome was a film bearing the same title as the book: it won an Oscar and the Palme d'Or at the Cannes film festival. This was his favoured medium for the expression of his ideas and observations, and a stream of films on the same theme kept his name before the public.Cousteau's fame earned him appointment by Prince Rainier as Director of the Oceanographie Institute in Monaco in 1957, a post he held until 1988. With its museum and research centre, it offered Cousteau a useful base for his worldwide activities.In the 1980s Cousteau turned again to technological development. Like others before him, he was concerned to reduce ships' fuel consumption by harnessing wind power. True to form, he raised grants from various sources to fund research and enlisted technical help, namely Lucien Malavard, Professor of Aerodynamics at the Sorbonne. Malavard designed a 44 ft (13.4 m) high non-rotating cylinder, which was fitted onto a catamaran hull, christened Moulin à vent. It was intended that its maiden Atlantic crossing in 1983 should herald a new age in ship propulsion, with large royalties to Cousteau. Unfortunately the vessel was damaged in a storm and limped to the USA under diesel power. A more robust vessel, the Alcyone, was fitted with two "Turbosails" in 1985 and proved successful, with a 40 per cent reduction in fuel consumption. However, oil prices fell, removing the incentive to fit the new device; the lucrative sales did not materialize and Alcyone remained the only vessel with Turbosails, sharing with Calypso Cousteau's voyages of adventure and exploration. In September 1995, Cousteau was among the critics of the decision by the French President Jacques Chirac to resume testing of nuclear explosive devices under the Mururoa atoll in the South Pacific.[br]Principal Honours and DistinctionsLégion d'honneur.
