16 Wankel, Felix
[br]b. 13 August 1902 Lahr, Black Forest, Germanyd. 9 October 1988 Lindau, Bavaria, Germany[br]German internal combustion engineer, inventor of the Wankel rotary engine.[br]Wankel was first employed at the German Aeronautical Research Establishment, where he worked on rotary valves and valve sealing techniques in the early 1930s and during the Second World War. In 1951 he joined NSU Motorenwerk AG, a motor manufacturer based at Neckarsulm, near Stuttgart, and began work on his rotary engine; the idea for this had first occurred to Wankel as early as 1929. He had completed his first design by 1954, and in 1957 his first prototype was tested. The Wankel engine has a three-pointed rotor, like a prism of an equilateral triangle but with the sides bowed outwards. This rotor is geared to a driveshaft and rotates within a closely fitting and slightly oval-shaped chamber so that, on each revolution, the power stroke is applied to each of the three faces of the rotor as they pass a single spark plug. Two or more rotors may be mounted coaxially, their power strokes being timed sequentially. The engine has only two moving parts, the rotor and the output shaft, making it about a quarter less in weight compared with a conventional piston engine; however, its fuel consumption is high and its exhaust emissions are relatively highly pollutant. The average Wankel engine speed is 5,500 rpm. The first production car to use a Wankel engine was the NSU Ro80, though this was preceded by the experimental NSU Spyder prototype, an open two-seater. The Japanese company Mazda is the only other automobile manufacturer to have fitted a Wankel engine to a production car, although licences were taken by Alfa Romeo, Peugeot- Citroën, Daimler-Benz, Rolls-Royce, Toyota, Volkswagen-Audi (the company that bought NSU in the mid-1970s) and many others; Daimler-Benz even produced a Mercedes C-111 prototype with a three-rotor Wankel engine. The American aircraft manufacturer Curtiss-Wright carried out research for a Wankel aero-engine which never went into production, but the Austrian company Rotax produced a motorcycle version of the Wankel engine which was fitted by the British motorcycle manufacturer Norton to a number of its models.While Wankel became director of his own research establishment at Lindau, on Lake Constance in southern Germany, Mazda continued to improve the rotary engine and by the time of Wankel's death the Mazda RX-7 coupé had become a successful, if not high-selling, Wankel -engined sports car.[br]Further ReadingN.Faith, 1975, Wankel: The Curious Story Behind the Revolutionary Rotary Engine, New York: Stein \& Day.IMcN -
17 Séguin, Louis
[br]b. 1869d. 1918[br]French co-designer, with his brother Laurent Séguin (b. 1883 Rhône, France; d. 1944), of the extremely successful Gnome rotary engines.[br]Most early aero-engines were adaptations of automobile engines, but Louis Séguin and his brother Laurent set out to produce a genuine aero-engine. They decided to build a "rotary" engine in which the crankshaft remained stationary and the cylinders rotated: the propeller was attached to the cylinders. The idea was not new, for rotary engines had been proposed by engineers from James Watt to Samuel P. Langley, rival of the Wright brothers. (An engine with stationary cylinders and a rotating crankshaftplus-propeller is classed as a "radial".) Louis Séguin formed the Société des Moteurs Gnome in 1906 to build stationary industrial engines. Laurent joined him to develop a lightweight engine specifically for aeronautical use. They built a fivecylinder air-cooled radial engine in 1908 and then a prototype seven-cylinder rotary engine. Later in the year the Gnome Oméga rotary, developing 50 hp (37 kW), was produced. This was test-flown in a Voisin biplane during June 1909. The Gnome was much lighter than its conventional rivals and surprisingly reliable in view of the technical problems of supplying rotating cylinders with the petrol-air mixture and a spark to ignite it. It was an instant success.Gnomes were mass-produced for use during the First World War. Both sides built and flew rotary engines, which were improved over the years until, by 1917, their size had grown to such an extent that a further increase was not practicable. The gyroscopic effects of a large rotating engine became a serious handicap to manoeuvrability, and the technical problems inherent in a rotary engine were accentuated.[br]Bibliography1912, L'Aérophile 20(4) (Louis Séguin's description of the Gnome).Further ReadingC.F.Taylor, 1971, "Aircraft Propulsion", Smithsonian Annals of Flight 1(4) (an account of the evolution of aircraft piston engines).A.Nahum, 1987, the Rotary Aero-Engine, London.JDS -
18 Diesel, Rudolph Christian Karl
SUBJECT AREA: Steam and internal combustion engines[br]b. 1858 Paris, Franced. 1913 at sea, in the English Channel[br]German inventor of the Diesel or Compression Ignition engine.[br]A German born in Paris, he was educated in Augsburg and later in Munich, where he graduated first in his class. There he took some courses under Professor Karl von Linde, pioneer of mechanical refrigeration and an authority on thermodynamics, who pointed out the low efficiency of the steam engine. He went to work for the Linde Ice Machine Company as an engineer and later as Manager; there he conceived a new basic cycle and worked out its thermodynamics, which he published in 1893 as "The theory and construction of a rational heat motor". Compressing air adiabatically to one-sixteenth of its volume caused the temperature to rise to 1,000°F (540°C). Injected fuel would then ignite automatically without any electrical system. He obtained permission to use the laboratories of the Augsburg-Nuremburg Engine Works to build a single-cylinder prototype. On test it blew up, nearly killing Diesel. He proved his principle, however, and obtained financial support from the firm of Alfred Krupp. The design was refined until successful and in 1898 an engine was put on display in Munich with the result that many business people invested in Diesel and his engine and its worldwide production. Diesel made over a million dollars out of the invention. The heart of the engine is the fuel-injection pump, which operates at a pressure of c.500 psi (35 kg/cm). The first English patent for the engine was in 1892. The firms in Augsburg sent him abroad to sell his engine; he persuaded the French to adopt it for submarines, Germany having refused this. Diesel died in 1913 in mysterious circumstances, vanishing from the Harwich-Antwerp ferry.[br]Further ReadingE.Diesel, 1937, Diesel, derMensch, das Werk, das Schicksal, Hamburg.

19 Ohain, Hans Joachim Pabst von
SUBJECT AREA: Aerospace[br]b. 14 December 1911 Dessau, Germany[br]German engineer who designed the first jet engine to power an aeroplane successfully.[br]Von Ohain studied engineering at the University of Göttingen, where he carried out research on gas-turbine engines, and centrifugal compressors in particular. In 1935 he patented a design for a jet engine (in Britain, Frank Whittle patented his jet-engine design in 1930). Von Ohain was recruited by the Heinkel company in 1936 to develop an engine for a jet aircraft. Ernst Heinkel was impressed by von Ohain's ideas and gave the project a high priority. The first engine was bench tested in September 1937. A more powerful version was developed and tested in air, suspended beneath a Heinkel dive-bomber, during the spring of 1939. A new airframe was designed to house the revolutionary power plant and designated the Heinkel He 178. A short flight was made on 24 August 1939 and the first recognized flight on 27 August. This important achievement received only a lukewarm response from the German authorities. Von Ohain's turbojet engine had a centrifugal compressor and developed a thrust of 380 kg (837 lb). An improved, more powerful, engine was developed and installed in a new twin-engined fighter design, the He 280. This flew on 2 April 1941 but never progressed beyond the prototype stage. By this time two other German companies, BMW and Junkers, were constructing successful turbojets with axial compressors: luckily for the Allies, Hitler was reluctant to pour his hard-pressed resources into this new breed of jet fighters. After the war, von Ohain emigrated to the United States and worked for the Air Force there.[br]Bibliography1929, "The evolution and future of aeropropulsion system", The Jet Age. 40 Years of Jet Aviation, Washington, DC: National Air \& Space Museum, Smithsonian Institution.Further ReadingVon Ohain's work is described in many books covering the history of aviation, and aero engines in particular, for example: R.Schlaifer and S.D.Heron, 1950, Development of Aircraft Engines and fuels, Boston.

20 Hamilton, Harold Lee (Hal)
[br]b. 14 June 1890 Little Shasta, California, USAd. 3 May 1969 California, USA[br]American pioneer of diesel rail traction.[br]Orphaned as a child, Hamilton went to work for Southern Pacific Railroad in his teens, and then worked for several other companies. In his spare time he learned mathematics and physics from a retired professor. In 1911 he joined the White Motor Company, makers of road motor vehicles in Denver, Colorado, where he had gone to recuperate from malaria. He remained there until 1922, apart from an eighteenth-month break for war service.Upon his return from war service, Hamilton found White selling petrol-engined railbuses with mechanical transmission, based on road vehicles, to railways. He noted that they were not robust enough and that the success of petrol railcars with electric transmission, built by General Electric since 1906, was limited as they were complex to drive and maintain. In 1922 Hamilton formed, and became President of, the Electro- Motive Engineering Corporation (later Electro-Motive Corporation) to design and produce petrol-electric rail cars. Needing an engine larger than those used in road vehicles, yet lighter and faster than marine engines, he approached the Win ton Engine Company to develop a suitable engine; in addition, General Electric provided electric transmission with a simplified control system. Using these components, Hamilton arranged for his petrol-electric railcars to be built by the St Louis Car Company, with the first being completed in 1924. It was the beginning of a highly successful series. Fuel costs were lower than for steam trains and initial costs were kept down by using standardized vehicles instead of designing for individual railways. Maintenance costs were minimized because Electro-Motive kept stocks of spare parts and supplied replacement units when necessary. As more powerful, 800 hp (600 kW) railcars were produced, railways tended to use them to haul trailer vehicles, although that practice reduced the fuel saving. By the end of the decade Electro-Motive needed engines more powerful still and therefore had to use cheap fuel. Diesel engines of the period, such as those that Winton had made for some years, were too heavy in relation to their power, and too slow and sluggish for rail use. Their fuel-injection system was erratic and insufficiently robust and Hamilton concluded that a separate injector was needed for each cylinder.In 1930 Electro-Motive Corporation and Winton were acquired by General Motors in pursuance of their aim to develop a diesel engine suitable for rail traction, with the use of unit fuel injectors; Hamilton retained his position as President. At this time, industrial depression had combined with road and air competition to undermine railway-passenger business, and Ralph Budd, President of the Chicago, Burlington \& Quincy Railroad, thought that traffic could be recovered by way of high-speed, luxury motor trains; hence the Pioneer Zephyr was built for the Burlington. This comprised a 600 hp (450 kW), lightweight, two-stroke, diesel engine developed by General Motors (model 201 A), with electric transmission, that powered a streamlined train of three articulated coaches. This train demonstrated its powers on 26 May 1934 by running non-stop from Denver to Chicago, a distance of 1,015 miles (1,635 km), in 13 hours and 6 minutes, when the fastest steam schedule was 26 hours. Hamilton and Budd were among those on board the train, and it ushered in an era of high-speed diesel trains in the USA. By then Hamilton, with General Motors backing, was planning to use the lightweight engine to power diesel-electric locomotives. Their layout was derived not from steam locomotives, but from the standard American boxcar. The power plant was mounted within the body and powered the bogies, and driver's cabs were at each end. Two 900 hp (670 kW) engines were mounted in a single car to become an 1,800 hp (l,340 kW) locomotive, which could be operated in multiple by a single driver to form a 3,600 hp (2,680 kW) locomotive. To keep costs down, standard locomotives could be mass-produced rather than needing individual designs for each railway, as with steam locomotives. Two units of this type were completed in 1935 and sent on trial throughout much of the USA. They were able to match steam locomotive performance, with considerable economies: fuel costs alone were halved and there was much less wear on the track. In the same year, Electro-Motive began manufacturing diesel-electrie locomotives at La Grange, Illinois, with design modifications: the driver was placed high up above a projecting nose, which improved visibility and provided protection in the event of collision on unguarded level crossings; six-wheeled bogies were introduced, to reduce axle loading and improve stability. The first production passenger locomotives emerged from La Grange in 1937, and by early 1939 seventy units were in service. Meanwhile, improved engines had been developed and were being made at La Grange, and late in 1939 a prototype, four-unit, 5,400 hp (4,000 kW) diesel-electric locomotive for freight trains was produced and sent out on test from coast to coast; production versions appeared late in 1940. After an interval from 1941 to 1943, when Electro-Motive produced diesel engines for military and naval use, locomotive production resumed in quantity in 1944, and within a few years diesel power replaced steam on most railways in the USA.Hal Hamilton remained President of Electro-Motive Corporation until 1942, when it became a division of General Motors, of which he became Vice-President.[br]Further ReadingP.M.Reck, 1948, On Time: The History of the Electro-Motive Division of General Motors Corporation, La Grange, Ill.: General Motors (describes Hamilton's career).PJGRBiographical history of technology > Hamilton, Harold Lee (Hal)
