2 Chapelon, André
[br]b. 26 October 1892 Saint-Paul-en-Cornillon, Loire, Franced. 29 June 1978 Paris, France[br]French locomotive engineer who developed high-performance steam locomotives.[br]Chapelon's technical education at the Ecole Centrale des Arts et Manufactures, Paris, was interrupted by extended military service during the First World War. From experience of observing artillery from the basket of a captive balloon, he developed a method of artillery fire control which was more accurate than that in use and which was adopted by the French army.In 1925 he joined the motive-power and rolling-stock department of the Paris-Orléans Railway under Chief Mechanical Engineer Maurice Lacoin and was given the task of improving the performance of its main-line 4–6–2 locomotives, most of them compounds. He had already made an intensive study of steam locomotive design and in 1926 introduced his Kylchap exhaust system, based in part on the earlier work of the Finnish engineer Kyläla. Chapelon improved the entrainment of the hot gases in the smokebox by the exhaust steam and so minimized back pressure in the cylinders, increasing the power of a locomotive substantially. He also greatly increased the cross-sectional area of steam passages, used poppet valves instead of piston valves and increased superheating of steam. PO (Paris-Orléans) 4–6–2s rebuilt on these principles from 1929 onwards proved able to haul 800-ton trains, in place of the previous 500-ton trains, and to do so to accelerated schedules with reduced coal consumption. Commencing in 1932, some were converted, at the time of rebuilding, into 4–8–0s to increase adhesive weight for hauling heavy trains over the steeply graded Paris-Toulouse line.Chapelon's principles were quickly adopted on other French railways and elsewhere.H.N. Gresley was particularly influenced by them. After formation of the French National Railways (SNCF) in 1938, Chapelon produced in 1941 a prototype rebuilt PO 2–10–0 freight locomotive as a six-cylinder compound, with four low-pressure cylinders to maximize expansive use of steam and with all cylinders steam-jacketed to minimize heat loss by condensation and radiation. War conditions delayed extended testing until 1948–52. Meanwhile Chapelon had, by rebuilding, produced in 1946 a high-powered, three-cylinder, compound 4–8–4 intended as a stage in development of a proposed range of powerful and thermally efficient steam locomotives for the postwar SNCF: a high-speed 4–6–4 in this range was to run at sustained speeds of 125 mph (200 km/h). However, plans for improved steam locomotives were then overtaken in France by electriflcation and dieselization, though the performance of the 4–8–4, which produced 4,000 hp (3,000 kW) at the drawbar for the first time in Europe, prompted modification of electric locomotives, already on order, to increase their power.Chapelon retired from the SNCF in 1953, but continued to act as a consultant. His principles were incorporated into steam locomotives built in France for export to South America, and even after the energy crisis of 1973 he was consulted on projects to build improved, high-powered steam locomotives for countries with reserves of cheap coal. The eventual fall in oil prices brought these to an end.[br]Bibliography1938, La Locomotive à vapeur, Paris: J.B.Bailière (a comprehensive summary of contemporary knowledge of every function of the locomotive).Further ReadingH.C.B.Rogers, 1972, Chapelon, Genius of French Steam, Shepperton: Ian Allan.1986, "André Chapelon, locomotive engineer: a survey of his work", Transactions of the Newcomen Society 58 (a symposium on Chapelon's work).Obituary, 1978, Railway Engineer (September/October) (makes reference to the technical significance of Chapelon's work).PJGR -

10 Giffard, Baptiste Henry Jacques (Henri)
[br]b. 8 February 1825 Paris, Franced. 14 April 1882 Paris, France[br]French pioneer of airships and balloons, inventor of an injector for steam-boiler feedwater.[br]Giffard entered the works of the Western Railway of France at the age of 16 but became absorbed by the problem of steam-powered aerial navigation. He proposed a steam-powered helicopter in 1847, but he then turned his attention to an airship. He designed a lightweight coke-burning, single-cylinder steam engine and boiler which produced just over 3 hp (2.2 kW) and mounted it below a cigar-shaped gas bag 44 m (144 ft) in length. A triangular rudder was fitted at the rear to control the direction of flight. On 24 September 1852 Giffard took off from Paris and, at a steady 8 km/h (5 mph), he travelled 28 km (17 miles) to Trappes. This can be claimed to be the first steerable lighter-than-air craft, but with a top speed of only 8 km/h (5 mph) even a modest headwind would have reduced the forward speed to nil (or even negative). Giffard built a second airship, which crashed in 1855, slightly injuring Giffard and his companion; a third airship was planned with a very large gas bag in order to lift the inherently heavy steam engine and boiler, but this was never built. His airships were inflated by coal gas and refusal by the gas company to provide further supplies brought these promising experiments to a premature end.As a draughtsman Giffard had the opportunity to travel on locomotives and he observed the inadequacies of the feed pumps then used to supply boiler feedwater. To overcome these problems he invented the injector with its series of three cones: in the first cone (convergent), steam at or below boiler pressure becomes a high-velocity jet; in the second (also convergent), it combines with feedwater to condense and impart high velocity to it; and in the third (divergent), that velocity is converted into pressure sufficient to overcome the pressure of steam in the boiler. The injector, patented by Giffard, was quickly adopted by railways everywhere, and the royalties provided him with funds to finance further experiments in aviation. These took the form of tethered hydrogen-inflated balloons of successively larger size. At the Paris Exposition of 1878 one of these balloons carried fifty-two passengers on each tethered "flight". The height of the balloon was controlled by a cable attached to a huge steam-powered winch, and by the end of the fair 1,033 ascents had been made and 35,000 passengers had seen Paris from the air. This, and similar balloons, greatly widened the public's interest in aeronautics. Sadly, after becoming blind, Giffard committed suicide; however, he died a rich man and bequeathed large sums of money to the State for humanitarian an scientific purposes.[br]Principal Honours and DistinctionsCroix de la Légion d'honneur 1863.Bibliography1860, Notice théorique et pratique sur l'injecteur automoteur.1870, Description du premier aérostat à vapeur.Further ReadingDictionnaire de biographie française.Gaston Tissandier, 1872, Les Ballons dirigeables, Paris.—1878, Le Grand ballon captif à vapeur de M.
