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.

4 Cobham, Sir Alan John
SUBJECT AREA: Aerospace[br]b. 6 May 1894 London, Englandd. 21 October 1973 British Virgin Islands[br]English pilot who pioneered worldwide air routes and developed an in-flight refuelling system which is in use today.[br]Alan Cobham was a man of many parts. He started as a veterinary assistant in France during the First World War, but transferred to the Royal Flying Corps in 1917. After the war he continued flying, by giving joy-rides and doing aerial photography work. In 1921 he joined the De Havilland Aircraft Company (see de Havilland, Geoffrey) as a test and charter pilot; he was also successful in a number of air races. During the 1920s Cobham made many notable flights to distant parts of the British Empire, pioneering possible routes for airline operations. During the early 1930s Sir Alan (he was knighted in 1926) devoted his attention to generating a public interest in aviation and to campaigning for more airfields. Cobham's Flying Circus toured the country giving flying displays and joy-rides, which for thousands of people was their first experience of flying.In 1933 Cobham planned a non-stop flight to India by refuelling his aircraft while flying: this was not a new idea but the process was still experimental. The flight was unsuccessful due to a fault in his aircraft, unrelated to the in-flight refuelling system. The following year Flight Refuelling Ltd was founded, and by 1939 two Short flying boats were operating the first inflight-refuelled service across the Atlantic. Inflight refuelling was not required during the early years of the Second World War, so Cobham turned to other projects such as thermal de-icing of wings, and a scheme which was not carried out, for delivering fighters to the Middle East by towing them behind Wellington bombers.After the Second World War the fortunes of Flight Refuelling Ltd were at a low ebb, especially when British South American Airways abandoned the idea of using in-flight refuelling. Then an American contract and the use of their tanker aircraft to ferry oil during the Berlin Airlift saved the day. In 1949 Cobham's chief designer, Peter Macgregor, came up with an idea for refuelling fighters using a probe and drogue system. A large tanker aircraft trailed a hose with a conical drogue at the free end. The fighter pilot manoeuvred the probe, fitted to his aircraft, so that it locked into the drogue, enabling fuel to be transferred. Since the 1950s this system has become the effective world standard.[br]Principal Honours and DistinctionsKnighted 1926. Air Force Cross 1926.Bibliography1978, A Time to Fly, ed.

6 Burroughs, Michael
SUBJECT AREA: Land transport[br]b. mid-twentieth century[br]English inventor who developed a new design of racing bicycle.[br]His father was a pattern-maker who worked for a time at the de Havilland aircraft factory at Hatfield, Hertfordshire; later he worked in an aeroplane-model shop before turning his attentions to boats and cars. Mike Burroughs left school at the age of 15 to become a self-taught engineer and inventor, regarding himself as an eccentric. Among other things, he invented a machine for packaging coins.In the 1970s he began to take an interest in bicycles, and he subjected the design and materials of existing machines of conventional design to searching reappraisal. As a result, Burroughs "reinvented" the bicycle, producing an entirely new concept. His father carved the shape of the single-piece frame in wood, from which a carbon-fibre cast was made. The machine proved to be very fast, but neither the sporting nor the industrial world showed much interest in it. Then in 1991 Rudi Terman, of the motor manufacturers Lotus, saw it and was impressed by its potential; he agreed to develop the machine further, but kept the details secret.The invention was released to an unsuspecting public at the Barcelona Olympic Games of 1992, ridden by Chris Boardman, who won the pursuit gold medal for Great Britain, a triumph for both rider and inventor. In subsequent months, Boardman went on to break several world records on the Lotus bicycle, including on 23 July 1993 the one-hour record with a distance of 52.27 km (32.48 miles).[br]Further ReadingC.Boardman and P.Liggett, 1994, The Fastest Man on Two Wheels: In Pursuit of Chris Boardman, London: Boxtree (looks at the revolutionary Lotus racing cycle designed by Burroughs).IMcN -
7 Mignet, Henri
SUBJECT AREA: Aerospace[br]b. 19 October 1893 Saintes, Franced. 31 August 1965 Bordeaux, France[br]French inventor of the Pou-du-Ciel or Flying Flea, a small aeroplane for the do-it-yourself constructor, popular in the 1930s.[br]Throughout the history of aviation there have been many attempts to produce a cheap and simple aeroplane for "the man in the street". The tiny Demoiselle built by Alberto Santos- Dumont in 1909 or the de Havilland Moth of 1925 are good examples, but the one which very nearly achieved this aim was Henri Mignet's Flying Flea of 1933. Mignet was a self-taught designer of light aircraft, which often incorporated his unorthodox ideas. His Pou-du-Ciel ("Sky Louse" or "Flying Flea") was unorthodox. The materials used in construction were conventional wood and fabric, but the control system departed from the usual wing plus tailplane (with elevators). The Flea had two wings in tandem. The rear wing was fixed, while the forward wing was hinged to allow the angle of incidence, and hence its lift, to be increased or decreased. Reducing the forward wing's lift would cause the Flea to dive. After Mignet's first flight, on 6 September 1933, and the publication of his book Le Sport de l'air, which explains how to build a Poudu-Ciel, a Pou-building craze started in France. Mignet's book was translated into English and 6,000 copies were sold in a month. During 1935 the craze spread to Britain, where a Flying Flea could be built for £50–£90, including the engine. After several fatal crashes, the aircraft was banned in 1936. A design fault in the control system was to blame, and although this was remedied the wave of popular enthusiasm vanished. Mignet continued to design light aircraft and during the Second World War he was working on a Pou- Maquis for use by the French Resistance but the war ended before the aircraft was ready. During the post-war years a series of Flying Flea derivatives appeared, but their numbers were small. However, the home-build movement in general has grown in recent years, a fact which would have pleased Henri Mignet, the "Patron Saint of Homebuilders".[br]Principal Honours and DistinctionsChevalier de la Légion d'honneur.
