3 Messerschmitt, Willi E.
SUBJECT AREA: Aerospace[br]b. 26 June 1898 Frankfurt-am-Main, Germanyd. 17 September 1978 Munich, Germany[br]German aircraft designer noted for successful fighters such as the Bf 109, one of the world's most widely produced aircraft.[br]Messerschmitt studied engineering at the Munich Institute of Tchnology and obtained his degree in 1923. By 1926 he was Chief Designer at the Bayerische Flugzeugwerke in Augsburg. Due to the ban on military aircraft in Germany following the First World War, his early designs included gliders, light aircraft, and a series of high-wing airliners. He began to make a major impact on German aircraft design once Hitler came to power and threw off the shackles of the Treaty of Versailles, which so restricted Germany's armed forces. In 1932 he bought out the now-bankrupt Bayerische Flugzeugwerke, but initially, because of enmity between himself and the German aviation minister, was not invited to compete for an air force contract for a single-engined fighter. However, in 1934 Messerschmitt designed the Bf 108 Taifun, a small civil aircraft with a fighter-like appearance. This displayed the quality of his design and the German air ministry was forced to recognize him. As a result, he unveiled the famous Bf 109 fighter which first flew in August 1935; it was used during the Spanish Civil War in 1936–9, and was to become one of the foremost combat aircraft of the Second World War. In 1938, after several name changes, the company became Messerschmitt Aktien-Gesellschaft (and hence a change of prefix from Bf to Me). During April 1939 a Messerschmitt aircraft broke the world air-speed record at 755.14 km/h (469.32 mph): it was entered in the FAI records as a Bf 109R, but was more accurately a new design designated Me 209V-1.During the Second World War, the 5/70P was progressively improved, and eventually almost 35,000 were built. Other successful fighters followed, such as the twin-engined Me 110 which also served as a bomber and night fighter. The Messerschmitt Me 262 twin-engined jet fighter, the first jet aircraft in the world to enter service, flew during the early years of the war, but it was never given a high priority by the High Command and only a small number were in service when the war ended. Another revolutionary Messerschmitt AG design was the Me 163 Komet, the concept of Professor Alexander Lippisch who had joined Messerschmitt's company in 1939; this was the first rocket-propelled fighter to enter service. It was a small tailless design capable of 880 km/hr (550 mph), but its duration under power was only about 10 minutes and it was very dangerous to fly. From late 1944 onwards it was used to intercept the United States Air Force bombers during their daylight raids. At the other end of the scale, Messerschmitt produced the Me 321 Gigant, a huge transport glider which was towed behind a flight of three Me 110s. Later it was equipped with six engines, but it was an easy target for allied fighters. This was a costly white elephant, as was his high-speed twin-engined Me 210 fighter-bomber project which nearly made his company bankrupt. Nevertheless, he was certainly an innovator and was much admired by Hitler, who declared that he had "the skull of a genius", because of the Me 163 Komet rocket-powered fighter and the Me 262.At the end of the war Messerschmitt was detained by the Americans for two years. In 1952 Messerschmitt became an aviation adviser to the Spanish government, and his Bf109 was produced in Spain as the Hispano Buchon for a number of years and was powered by Rolls-Royce Merlin engines. A factory was also constructed in Egypt to produce aircraft to Messerschmitt's designs. His German company, banned from building aircraft, produced prefabricated houses, sewing machines and, from 1953 to 1962, a series of bubble-cars: the KR 175 (1953–55) and the KR 200 (1955–62) were single-cylinder three-wheeled bubble-cars, and the Tiger (1958–62) was a twin-cylinder, 500cc four-wheeler. In 1958 Messerschmitt resumed aircraft construction in Germany and later became the Honorary Chairman of the merged Messerschmitt-Bölkow-Blohm company (now part of the Franco-German Eurocopter company).[br]Further Readingvan Ishoven, 1975, Messerschmitt.

4 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

5 Keller, Arthur
[br]b. 18 August 1901 New York City, New York, USA d. 1983[br]American engineer and developer of telephone switching equipment who was instrumental in the development of electromechanical recording and stereo techniques.[br]He obtained a BSc in electrical engineering at Cooper Union for the Advancement of Science and Art, New York, in 1923 and an MSc from Yale University, and he did postgraduate work at Columbia University. Most of the time he was also on the staff of the Bell Telephone Laboratories. The Bell Laboratories and its predecessors had a long tradition in research in speech and hearing, and in a team of researchers under H.C. Harrison, Keller developed a number of definite improvements in electrical pick-ups, gold-sputtering for matrix work and electrical disc recording equipment. From 1931 onwards the team at Bell Labs developed disc recording for moving pictures and entered into collaboration with Leopold Stokowski and the Philadelphia Orchestra concerning transmission and recording of high-fidelity sound over wires, and stereo techniques. Keller developed a stereo recording system for disc records independently of A.D. Blumlein that was used experimentally in the Bell Labs during the 1930s. During the Second World War Keller was in a team developing sonar (sound navigation and ranging) for the US Navy. After the war he concentrated on switching equipment for telephone exchanges and developed a miniature relay. In 1966 he retired from the Bell Laboratories, where he had been Director of several departments, ending as Director of the Switching Apparatus Laboratory. After retirement he was a consultant internationally, concerning electromechanical devices in particular. When, in 1980, the Bell Laboratories decided to issue LP re-recordings of a number of the experimental records made during the 1930s, Keller was brought in from retirement to supervise the project and decide on the selections.[br]BibliographyKeller was inventor or co-inventor of forty patents, including: US patent no. 2,114,471 (the principles of stereo disc recording); US patent no. 2,612,586 (tape guides with air lubrication); US patent no. 3,366,901 (a miniature crossbar switch).Apart from a large number of highly technical papers, Keller also wrote the article "Phonograph" in the 1950 and 1957 editions of Encyclopaedia Britannica.1986, Reflections of a Stereo Pioneer, San Francisco: San Francisco Press (an honest, personal account).GB-N -
6 Barsanti, Eugenio
SUBJECT AREA: Steam and internal combustion engines[br]b. 1821 Italyd. 1864 Liège, Belgium[br]Italian co-inventor of the internal combustion engine; lecturer in mechanics and hydraulics.[br]A trained scientist and engineer, Barsanti became acquainted with a distinguished engineer, Felice Matteucci, in 1851. Their combined talents enabled them to produce a number of so-called free-piston atmospheric engines from 1854 onwards. Using a principle demonstrated by the Swiss engineer Isaac de Rivaz in 1827, the troublesome explosive shocks encountered by other pioneers were avoided. A piston attached to a long toothed rack was propelled from beneath by the expansion of burning gas and allowed unrestricted movement. A resulting partial vacuum enabled atmospheric pressure to return the piston and produce the working stroke. Electric ignition was a feature of all the Italian engines.With many successful applications, a company was formed in 1860. A 20 hp (15 kW) engine stimulated much interest. Attempts by John Cockerill of Belgium to mass-produce small power units of up to 4 hp (3 kW) came to an abrupt end; during the negotiations Barsanti contracted typhoid fever and later died. The project was abandoned, but the working principle of the Italian engine was used successfully in the Otto-Langen engine of 1867.[br]Bibliography13 May 1854, British Provisional Patent no. 1,072 (the Barsanti and Matteucci engine).12 June 1857, British patent no. 1,655 (contained many notable improvements to the design).Further ReadingThe Engineer (1858) 5:73–4 (for an account of the Italian engine).Vincenzo Vannacci, 1955, L'invenzione del motore a scoppio realizzota dai toscani Barsanti e Matteucci 1854–1954, Florence.KAB -
7 de Havilland, Sir Geoffrey
SUBJECT AREA: Aerospace[br]b. 27 July 1882 High Wycombe, Buckinghamshire, Englandd. 21 May 1965 Stanmore, Middlesex, England[br]English designer of some eighty aircraft from 1909 onwards.[br]Geoffrey de Havilland started experimenting with aircraft and engines of his own design in 1908. In the following year, with the help of his friend Frank Hearle, he built and flew his first aircraft; it crashed on its first flight. The second aircraft used the same engine and made its first flight on 10 September 1910, and enabled de Havilland to teach himself to fly. From 1910 to 1914 he was employed at Farnborough, where in 1912 the Royal Aircraft Factory was established. As Chief Designer and Chief Test Pilot he was responsible for the BE 2, which was the first British military aircraft to land in France in 1914.In May 1914 de Havilland went to work for George Holt Thomas, whose Aircraft Manufacturing Company Ltd (Airco) of Hendon was expanding to design and build aircraft of its own design. However, because de Havilland was a member of the Royal Flying Corps Reserve, he had to report for duty when war broke out in August. His value as a designer was recognized and he was transferred back to Airco, where he designed eight aircraft in four years. Of these, the DH 2, DH 4, DH 5, DH 6 and DH 9 were produced in large numbers, and a modified DH 4A operated the first British cross- Channel air service in 1919.On 25 September 1920 de Havilland founded his own company, the De Havilland Aircraft Company Ltd, at Stag Lane near Edgware, London. During the 1920s and 1930s de Havilland concentrated on civil aircraft and produced the very successful Moth series of small biplanes and monoplanes, as well as the Dragon, Dragon Rapide, Albatross and Flamingo airliners. In 1930 a new site was acquired at Hatfield, Hertfordshire, and by 1934 a modern factory with a large airfield had been established. His Comet racer won the England-Australia air race in 1934 using de Havilland engines. By this time the company had established very successful engine and propeller divisions. The Comet used a wooden stressed-skin construction which de Havilland developed and used for one of the outstanding aircraft of the Second World War: the Mosquito. The de Havilland Engine Company started work on jet engines in 1941 and their Goblin engine powered the Vampire jet fighter first flown by Geoffrey de Havilland Jr in 1943. Unfortunately, Geoffrey Jr and his brother John were both killed in flying accidents. The Comet jet airliner first flew in 1949 and the Trident in 1962, although by 1959 the De Havilland Company had been absorbed into Hawker Siddeley Aviation.[br]Principal Honours and DistinctionsKnight Bachelor 1944.
