  • 8 Phillips, Horatio Frederick

    SUBJECT AREA: Aerospace
    [br]
    b. 2 February 1845 London, England
    d. 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.

  • 10 Cayley, Sir George

    SUBJECT AREA: Aerospace
    [br]
    b. 27 December 1773 Scarborough, England
    d. 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.

    Bibliography
    Cayley 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).
