The Aeroplane Speaks. Fifth Edition

THE HANRIOT AND PONNIER MONOPLANES.--In 1909 came the first Hanriot with 50 h.p. 6-cylinder Buchet engine, and in 1910 the famous "Henrietta" type with E.N.Vs. and stationary Clergets. 1911 came the Clerget two-seater entered in French Military Trials, and 1912 the 100 h.p. Hanriot-Pagny monoplane which took part in British Military Trials. Sister machines of the same year were the single seater with 50 h.p. Gnome and the 100 h.p. Gnome racer with stripped chassis. In 1913 the Ponnier-Pagny racing monoplane with 160 h.p. Le Rhone competed in the Gordon-Bennett race, doing about 130 miles in the hour. The 60 h.p. Ponnier biplane was the first successful French scout tractor biplane. THE WRIGHT BIPLANE.--The first power flights were made, 1903, on a converted glider fitted with 16 h.p. motor. The prone position of the pilot will be noted. By 1907 the machine had become reasonably practical with 40 h.p. motor. On this the first real flying in the world was done. In 1910 the miniature racing Wright was produced; also the type with a rear elevator in addition to one in front. Soon afterwards the front elevator disappeared, and the machine became the standard American exhibition and school machine for four years. In 1915 a machine with enclosed fuselage was produced. THE BLACKBURN MONOPLANES.--In 1909 was built the curious four-wheeled parasol-type machine with 35 h.p. Green engine and chain transmission, on which flying was done at Saltburn. In 1911 the Isaacson-engined machine was built, together with a 50 h.p. Gnome single-seater on which Mr. Hucks started in the Circuit of Britain race. In 1912 another 50 h.p. single-seater was built on which a good deal of school work was done. A more advanced machine appeared in 1913 and a two-seater with 80 h.p. Gnome did a great deal of cross-country work in 1913-14.
