125 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 -
126 Langley, Samuel Pierpont
SUBJECT AREA: Aerospace[br]b. 22 August 1834 Roxbury, Massachusetts, USAd. 27 February 1906 Aiken, South Carolina, USA[br]American scientist who built an unsuccessful aeroplane in 1903, just before the success of the Wright brothers.[br]Professor Langley was a distinguished mathematician and astronomer who became Secretary of the Smithsonian Institution (US National Museum) in 1887. He was also interested in aviation and embarked on a programme of experiments with a whirling arm to test wings and with a series of free-flying models. In 1896 one of his steam-powered models made a flight of 4,199 ft (1,280 m): this led to a grant from the Government to subsidize the construction of a manned aeroplane. Langley commissioned Stephen M. Balzer, an automobile engine designer, to build a lightweight aero-engine and appointed his assistant, Charles M.Manly, to oversee the project. After many variations, including rotary and radical designs, two versions of the Balzer-Manly engine were produced, one quarter size and one full size. In August 1903 the small engine powered a model which thus became the first petrol-engined aeroplane to fly. Langley designed his full-size aeroplane (which he called an Aerodrome) with tandem wings and a cruciform tail unit. The Balzer-Manly engine drove two pusher propellers. Manly was to be the pilot as Langley was now almost 70 years old. Most early aviators tested their machines by making tentative hops, but Langley decided to launch his Aerodrome by catapult from the roof of a houseboat on the Potomac river. Two attempts were made and on both occasions the Aerodrome crashed into the river: catapult problems and perhaps a structural weakness were to blame. The second crash occurred on 8 December 1903 and it is ironic that the Wright brothers, with limited funds and no Government support, successfully achieved a manned flight just nine days later. Langley was heartbroken. After his death there followed a strange affair in 1914 when Glenn Curtiss took Langley's Aerodrome, modified it, and tried to prove that but for the faulty catapult it would have flown before the Wrights' Flyer. A brief flight was made with floats instead of the catapult, and it flew rather better after more extensive modifications and a new engine.[br]Bibliography1897, Langley Memoir on Mechanical Flight, Part 1, Washington, DC: Smithsonian Institution; 1911, Part 2.Further ReadingJ.Gordon Vaeth, 1966, Langley: Man of Science and Flight, New York (biography).Charles H.

127 Wenham, Francis Herbert
SUBJECT AREA: Aerospace[br]b. 1824 London, Englandd. 11 August 1908 Folkestone, England[br]English engineer, inventor and pioneer aerodynamicist who built the first wind tunnel.[br]Wenham trained as a marine engineer and later specialized in screw propellers and high-pressure engines. He had many interests. He took his steamboat to the Nile and assisted the photographer F.Frith to photograph Egyptian tombs by devising a series of mirrors to deflect sunlight into the dark recesses. He experimented with gas engines and produced a hot-air engine. Wenham was a leading, if controversial, figure in the Microscopical Society and a member of the Royal Photographic Society; he developed an enlarger.Wenham was interested in both mechanical and lighter-than-air flight. One of his friends was James Glaisher, a well-known balloonist who made many ascents to gather scientific information. When the (Royal) Aeronautical Society of Great Britain was founded in 1866, the Rules were drawn up by Wenham, Glaisher and the Honorary Secretary, F.W.Brearey. At the first meeting of the Society, on 27 June 1866, "On aerial locomotion and the laws by which heavy bodies impelled through the air are sustained" was read by Wenham. In his paper Wenham described his experiments with a whirling arm (used earlier by Cayley) to measure lift and drag on flat surfaces inclined at various angles of incidence. His studies of birds' wings and, in particular, their wing loading, showed that they derived most of their lift from the front portion, hence a long, thin wing was better than a short, wide one. He published illustrations of his glider designs covering his experiments of c. 1858–9. One of these had five slender wings one above the other, an idea later developed by Horatio Phillips. Wenham had some success with a model, but no real success with his full-size gliders.In 1871, Wenham and John Browning constructed the first wind tunnel designed for aeronautical research. It utilized a fan driven by a steam engine to propel the air and had a working section of 18 in. (116 cm). Wenham continued to play an important role in aeronautical matters for many years, including a lengthy exchange of ideas with Octave Chanute from 1892 onwards.[br]Principal Honours and DistinctionsHonorary Member of the (Royal) Aeronautical Society.BibliographyWenham published many reports and papers. These are listed, together with a reprint of his paper "Aerial locomotion", in the Journal of the Royal Aeronautical Society (August 1958).Further ReadingTwo papers by J.Laurence Pritchard, 1957, "The dawn of aerodynamics" Journal of the Royal Aeronautical Society (March); 1958, "Francis Herbert Wenham", Journal of the Royal Aeronautical Society (August) (both papers describe Wenham and his work).J.E.Hodgson, 1924, History of Aeronautics in Great Britain, London.JDSBiographical history of technology > Wenham, Francis Herbert
