1 Lilienthal, Otto
SUBJECT AREA: Aerospace[br]b. 23 May 1848 Anklam, Prussia (now Germany)d. 10 August 1896 Berlin, Germany[br]German glider pioneer, the first to make a controlled flight using wings.[br]Otto Lilienthal and his brother Gustav developed an interest in flying as boys, when they studied birds in flight, built models and even tried to fit wings to their arms. Gustav went on to become a successful architect while Otto, after a brilliant scholastic career, became a mechanical engineer. Otto was able to devote his spare time to the problems of flight, and Gustav helped when his work allowed. They considered manpowered and mechanically powered projects, but neither looked hopeful so they turned to gliding. Otto published his research work in a book, Bird Flight as a Basis for Aviation. By 1889 Otto Lilienthal was ready to test his first full-size gliders. No. 1 and No. 2 were not successful, but No. 3, built in 1891, showed promise. He gradually improved his designs and his launching sites as he gained experience. To take off he ran downhill carrying his hang-glider until it became airborne, then he controlled it by swinging his body weight in the appropriate direction. He even built an artificial mound near Berlin so that he could take off into the wind whichever way it was blowing.In all, Lilienthal built some eighteen gliders with various wing shapes, including biplanes. By 1895 he was planning movable control surfaces (operated by head movement) and a powered version using a carbonic acid gas motor. Unfortunately, Lilienthal crashed and died of his injuries before these ideas could be tested. In all, he made over two thousand flights covering distances up to 300 m (300 yds. Many of these flights were recorded on photographs and so generated an interest in flying. Lilienthal's achievements also encouraged other pioneers, such as Percy Pilcher in Britain, and Octave Chanute and the Wright brothers in the United States.[br]Bibliography1899, Der Vogelflug als Grundlage der Fliegekunst, Berlin, reprinted c. 1977; repub. in English, 1911, as Bird Flight as a Basis for Aviation.Further ReadingCharles H.Gibbs-Smith, 1985, Aviation, London (provides a detailed account of Lilienthal's gliders).P.H.Lilienthal, 1978, "Die Lilienthal Gebrüder", Aerospace (Royal Aeronautical Society) (January) (for more personal information)."The Lilienthal and Pilcher gliders compared", Flight (1 January 1910 and 8 January 1910) (for details about and plans of a typical Lilienthal glider).JDS -

3 Chanute, Octave Alexandre
SUBJECT AREA: Aerospace[br]b. 18 February 1832 Paris, Franced. 24 November 1910 Chicago, USA[br]American engineer, developer of successful hang-gliders in the 1890s and disseminator of aeronautical information.[br]Chanute was born in Paris, but from the age of 6 he lived in the United States, where he became a prominent railway engineer. He developed an interest in aviation relatively late in life, and in fact built his first glider at the age of 64. Before that, he had collected all the information he could find on aviation, especially on the work of Otto Lilienthal in Germany. In 1894 he published an account of these researches in a classic work, Progress in Flying Machines.By 1896 Chanute was ready to carry out practical experiments of his own and designed a series of hang-gliders. He started with a Lilienthal-type monoplane and progressed to his very successful biplane glider. He used a bridge-truss method of cross-bracing to give his wings the required strength, a system used by many of his successors, including the Wright brothers. Chanute's gliders were flown on the shore of Lake Michigan by his two young assistants A.M.Herring and W.Avery. The biplane glider made some seven hundred flights without mishap, covering up to 100 m (110 yds). In 1898 Herring fitted an engine into a modified glider and claimed to have made two short hops.In 1900 the Wright brothers made contact with Chanute and sought his advice, which he readily gave, indeed, he became one of their most trusted advisors. In 1903 Chanute travelled to Paris and gave an illustrated lecture describing his own and the Wrights' gliding successes, generating much interest amongst European aviators.[br]Principal Honours and DistinctionsRoyal Aeronautical Society Gold Medal 1910.Bibliography1894, Progress in Flying Machines, New York (Chanute's classic work).Further ReadingC.H.Gibbs-Smith, 1986, Aviation, London.—1965, The Invention of the Aeroplane 1799–1909, London (both describe Chanute's place in the history of aviation).T.D.Crouch, A Dream of Wings, Americans and the Airplane 1875–1905 (includes several chapters on Chanute and a comprehensive bibliography).Chanute is also mentioned in most of the biographies of the Wright brothers.JDSBiographical history of technology > Chanute, Octave Alexandre

4 Wright, Wilbur
SUBJECT AREA: Aerospace[br]b. 16 April 1867 Millville, Indiana, USAd. 30 May 1912 Dayton, Ohio, USA[br]American co-inventor, with his brother Orville Wright (b. 19 August 1871 Dayton, Ohio, USA; d. 30 January 1948 Dayton, Ohio, USA), of the first powered aeroplane capable of sustained, controlled flight.[br]Wilbur and Orville designed and built bicycles in Dayton, Ohio. In the 1890s they developed an interest in flying which led them to study the experiments of gliding pioneers such as Otto Lilienthal in Germany, and their fellow American Octave Chanute. The Wrights were very methodical and tackled the many problems stage by stage. First, they developed a method of controlling a glider using movable control surfaces, instead of weight-shifting as used in the early hand-gliders. They built a wind tunnel to test their wing sections and by 1902 they had produced a controllable glider. Next they needed a petrol engine, and when they could not find one to suit their needs they designed and built one themselves.On 17 December 1903 their Flyer was ready and Orville made the first short flight of 12 seconds; Wilbur followed with a 59-second flight covering 853 ft (260 m). An improved design, Flyer II, followed in 1904 and made about eighty flights, including circuits and simple ma-noeuvres. In 1905 Flyer III made several long flights, including one of 38 minutes covering 24½ miles (39 km). Most of the Wrights' flying was carried out in secret to protect their patents, so their achievements received little publicity. For a period of two and a half years they did not fly, but they worked to improve their Flyer and to negotiate terms for the sale of their invention to various governments and commercial syndi-cates.In 1908 the Wright Model A appeared, and when Wilbur demonstrated it in France he astounded the European aviators by making several flights lasting more than one hour and one of 2 hours 20 minutes. Considerable numbers of the Model A were built, but the European designers rapidly caught up and overtook the Wrights. The Wright brothers became involved in several legal battles to protect their patents: one of these, with Glenn Curtiss, went on for many years. Wilbur died of typhoid fever in 1912. Orville sold his interest in the Wright Company in 1915, but retained an interest in aeronautical research and lived on to see an aeroplane fly faster than the speed of sound.[br]Principal Honours and DistinctionsRoyal Aeronautical Society (London) Gold Medal (awarded to both Wilbur and Orville) May 1909.
