The Aeroplane Speaks. Fifth Edition

In 1910 a number of novel machines were produced. The Avis with Anzani engine was flown by the Hon. Alan Boyle. Note the cruciform universally jointed tail. The Goupy with 50 h.p. Gnome was an early French tractor, notable for its hinging wing-tips. The Farman was a curious "knock-up" job, chiefly composed of standard box-kite fittings. The Sommer with 50 h.p. Gnome was a development of the box-kite with a shock-breaking chassis. The Savary, also French, was one of the first twin tractors to fly. The model illustrated had an E.N.V. engine. Note position of the rudders on the wing tips. The Austrian Etrich was the first successful machine of the Taube class ever built. INTERESTING MACHINES, 1910.--The Werner monoplane with E.N.V. engine, combined shaft and chain drive, was a variant of the de Pischoff. The Macfie biplane was a conventional biplane with 50 h.p. Gnome and useful originalities. The Valkyrie monoplane, another British machine, was a "canard" monoplane with propeller behind the pilot and in front of main plane. The Weiss monoplane was a good British effort at inherent stability. The Tellier monoplane was a modified Bleriot with Antoinette proportions. The Howard Wright biplane was a pusher with large lifting monoplane tail. The Dunne biplane was another British attempt at inherent stability. The Jezzi biplane was an amateur built twin-propeller. SOME INTERESTING MACHINES, 1911.--The Compton-Paterson biplane was very similar to the early Curtiss pusher; it had a 50 h.p. Gnome. The Sloan bicurve was a French attempt at inherent stability with 50 h.p. Gnome and tractor screw. The Paulhan biplane was an attempt at a machine for military purposes to fold up readily for transport. The Sanders was a British biplane intended for rough service. The Barnwell monoplane was the first Scottish machine to fly; it had a horizontally opposed Scottish engine. The Harlan monoplane was an early German effort; note position of petrol tank.
