13 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.

14 Laval, Carl Gustaf Patrik de
SUBJECT AREA: Agricultural and food technology, Electricity, Mechanical, pneumatic and hydraulic engineering, Steam and internal combustion engines[br]b. 9 May 1845 Orsa, Swedend. 2 February 1913 Stockholm, Sweden[br]Swedish inventor of an advanced cream separator and a steam turbine.[br]Gustaf de Laval was educated at the Stockholm Technical Institute and Uppsala University. He proved to have an unfailing vigour and variety in his inventive talent, for his interests ranged from electric lighting and electrometallurgy to aerodynamics. In the 1890s he employed over one hundred engineers to develop his inventions, but he was best known for two: the cream separator and a steam turbine. In 1877 he invented the high-speed centrifugal cream separator, which was probably the greatest advance in butter-making up to that time. By 1880 the separators were being successfully marketed all over the world, for they were quickly adopted in larger dairies where they effected enormous savings in labour and space. He followed this with various devices for the dairy industry, including a vacuum milking machine perfected in 1913. In c. 1882, de Laval invented a turbine on the principle of Hero's engine, but he quickly turned his attention to the impulse type, which was like Branca's, with a jet of steam impinging on a set of blades around the periphery of a wheel. He applied for a British patent in 1889. The steam was expanded in a single stage from the initial to the final pressure: to secure economy with the steam issuing at high velocity, the blades also had to rotate at high velocity. An early 5 hp (3.7 kW) turbine rotated at 30,000 rpm, so reduction gearing had to be introduced. Production started in Sweden in 1893 and in other countries at about the same time. In 1892 de Laval proposed employing one of his turbines of 15 hp (11 kW) in an experimental launch, but there is no evidence that it was ever actually installed in a vessel. However, his turbines were popular for powering electric generating sets for lighting textile mills and ships, and by 1900 were available in sizes up to 300 bhp (224 kW).[br]Bibliography1889, British patent no. 7,143 (steam turbine).Further ReadingT.Althin, 1943, Life of de Laval, Stockholm (a full biography).T.I.Williams (ed.), 1969, A Biographical Dictionary of Scientists, London: A. \& C.
