1 Junkers, Hugo
SUBJECT AREA: Aerospace[br]b. 3 February 1859 Rheydt, Germanyd. 3 February 1935 Munich, Germany[br]German aircraft designer, pioneer of all-metal aircraft, including the world's first real airliner.[br]Hugo Junkers trained as an engineer and in 1895 founded the Junkers Company, which manufactured metal products including gas-powered hot-water heaters. He was also Professor of Thermodynamics at the high school in Aachen. The visits to Europe by the Wright brothers in 1908 and 1909 aroused his interest in flight, and in 1910 he was granted a patent for a flying wing, i.e. no fuselage and a thick wing which did not require external bracing wires. Using his sheet-metal experience he built the more conventional Junkers J 1 entirely of iron and steel. It made its first flight in December 1915 but was rather heavy and slow, so Junkers turned to the newly available aluminium alloys and built the J 4 bi-plane, which entered service in 1917. To stiffen the thin aluminium-alloy skins, Junkers used corrugations running fore and aft, a feature of his aircraft for the next twenty years. Incidentally, in 1917 the German authorities persuaded Junkers and Fokker to merge, but the Junkers-Fokker Company was short-lived.After the First World War Junkers very rapidly converted to commercial aviation, and in 1919 he produced a single-engined low-wing monoplane capable of carrying four passengers in an enclosed cabin. The robust all-metal F 13 is generally accepted as being the world's first airliner and over three hundred were built and used worldwide: some were still in service eighteen years later. A series of low-wing transport aircraft followed, of which the best known is the Ju 52. The original version had a single engine and first flew in 1930; a three-engined version flew in 1932 and was known as the Ju 52/3m. This was used by many airlines and served with the Luftwaffe throughout the Second World War, with almost five thousand being built.Junkers was always ready to try new ideas, such as a flap set aft of the trailing edge of the wing that became known as the "Junkers flap". In 1923 he founded a company to design and manufacture stationary diesel engines and aircraft petrol engines. Work commenced on a diesel aero-engine: this flew in 1929 and a successful range of engines followed later. Probably the most spectacular of Junkers's designs was his G 38 airliner of 1929. This was the world's largest land-plane at the time, with a wing span of 44 m (144 ft). The wing was so thick that some of the thirty-four passengers could sit in the wing and look out through windows in the leading edge. Two were built and were frequently seen on European routes.[br]Bibliography1923, "Metal aircraft construction", Journal of the Royal Aeronautical Society, London.Further ReadingG.Schmitt, 1988, Hugh Junkers and His Aircraft, Berlin.1990, Jane's Fighting Aircraft of World War I, London: Jane's (provides details of Junkers's aircraft).J.Stroud, 1966, European Transport Aircraft since 1910, London.P.

5 Short, Hugh Oswald
SUBJECT AREA: Aerospace[br]b. 16 January 1883 Derbyshire, Englandd. 4 December 1969 Haslemere, England[br]English co-founder, with his brothers Horace Short (1872–1917) and Eustace (1875–1932), of the first company to design and build aeroplanes in Britain.[br]Oswald Short trained as an engineer; he was largely self-taught but was assisted by his brothers Eustace and Horace. In 1898 Eustace and the young Oswald set up a balloon business, building their first balloon in 1901. Two years later they sold observation balloons to the Government of India, and further orders followed. Meanwhile, in 1906 Horace designed a high-altitude balloon with a spherical pressurized gondola, an idea later used by Auguste Piccard, in 1931. Horace, a strange genius with a dominating character, joined his younger brothers in 1908 to found Short Brothers. Their first design, based on the Wright Flyer, was a limited success, but No. 2 won a Daily Mail prize of £1,000. In the same year, 1909, the Wright brothers chose Shorts to build six of their new Model A biplanes. Still using the basic Wright layout, Horace designed the world's first twin-engined aeroplane to fly successfully: it had one engine forward of the pilot, and one aft. During the years before the First World War the Shorts turned to tractor biplanes and specialized in floatplanes for the Admiralty.Oswald established a seaplane factory at Rochester, Kent, during 1913–14, and an airship works at Cardington, Bedfordshire, in 1916. Short Brothers went on to build the rigid airship R 32, which was completed in 1919. Unfortunately, Horace died in 1917, which threw a greater responsibility onto Oswald, who became the main innovator. He introduced the use of aluminium alloys combined with a smooth "stressed-skin" construction (unlike Junkers, who used corrugated skins). His sleek biplane the Silver Streak flew in 1920, well ahead of its time, but official support was not forthcoming. Oswald Short struggled on, trying to introduce his all-metal construction, especially for flying boats. He eventually succeeded with the biplane Singapore, of 1926, which had an all-metal hull. The prototype was used by Sir Alan Cobham for his flight round Africa. Several successful all-metal flying boats followed, including the Empire flying boats (1936) and the ubiquitous Sunderland (1937). The Stirling bomber (1939) was derived from the Sunderland. The company was nationalized in 1942 and Oswald Short retired the following year.[br]Principal Honours and DistinctionsHonorary Fellow of the Royal Aeronautical Society.

6 Yarrow, Sir Alfred Fernandez
SUBJECT AREA: Ports and shipping[br]b. 13 January 1842 London, Englandd. 24 January 1932 London, England[br]English shipbuilder, naval architect, engineer and philanthropist.[br]At the conclusion of his schooling in the South of England, Yarrow became an indentured apprentice to the Thames engine-builder Ravenhill. During this five-year period various incidents and meetings sharpened his interest in scientific matters and he showed the skills that in later years were to be so beneficial to shipbuilding. For two years he acted as London representative for Ravenhill before joining up with a Mr Hedley to form a shipyard on the Isle of Dogs. The company lasted from 1868 until 1875 and in that period produced 350 small launches and other craft. This massive output enabled Yarrow to gain confidence in many aspects of ship design. Within two years of setting out on his own he built his first ship for the Royal Navy: a torpedo boat, then at the cutting edge of technology.In the early 1890s the company was building watertube boilers and producing destroyers with speeds in excess of 27 knots (50 km/h); it built the Russian destroyer Sokol, did pioneering work with aluminium and with high-tensile steels and worked on shipboard equipment to nullify vibrational effects. With the closure of most of the Thames shipyards and the run-down in skilled labour, Yarrow decided that the shipyard must move to some other part of the United Kingdom. After careful deliberation a green field site to the west of Glasgow was chosen, and in 1908 their first Clyde-built destroyer was launched. The company expanded, more building berths were arranged, boiler construction was developed and over the years they became recognized as specialists in smaller highspeed craft and in "knock down" ships for other parts of the world.Yarrow retired in 1913, but at the commencement of the First World War he returned to help the yard produce, in four years, twenty-nine destroyers with speeds of up to 40 knots (74 km/h). At the end of hostilities he gave of his time and money to many charities, including those for ex-servicemen. He left a remarkable industrial organization which remains to this day the most prolific builder of surface craft for the Royal Navy.[br]Principal Honours and DistinctionsCreated Baronet 1916.
