FLIGHT, JANUARY 3, 1930 EARLY INGENUITY REFERENCE was made on theprevious page to the 1911type Martin Handasyde monoplane. A little more of this machine is shown in the upper photograph on the left. In this view the skid under the " nose," terminating in a " spoon " shoe, can be clearly seen, as well as the kingpost system of wing bracing employed. The earliest Martin Handasyde monoplanes, produced at Brooklands were strongly in- fluenced in their design by the French Antoinette monoplanes, and the engine fitted in the machine illustrated, was in fact, an Antoin- ette water-cooled engine Actually it would be more correct to say that it was a steam-cooled engine, for the water in the jackets was permitted to boil, and the steam was condensed in large condensers mounted along the flat sides of the triangular-section fuselage. In view of "the modern tendency to revert to evaporative cooling, it is interesting to recall that this was employed fairly successfully 19 years ago. The Star monoplane shown on the left was produced in 1911; and was chiefly remarkable for a feature which does not, un- fortunately, show in the photo- graph. The two elevator flaps, of diamond shape, were independently operated to give lateral control. That they failed to do so is scarcely surprising nowadays. •if <»ipwil^pll The photographs above show two machines which, each in its own way, marked a milestone. On the left is Commander:h\vann's Avro, the first tractor seaplane to get off the water. In the photo, Sippe is in the cockpit. On the right Mr. Horatio Barber's " Viking," a 1912 single-engined twin-screw biplane. Of the two 1912 types shown above, that on the left is the famous Maurice Farman " Longhorn " with Grahame White the nacelle and Louis Noel standing by the wing. The machine on the right is the Avro enclosed cabin monoplane rted with Vialc radial air-cooled engine. FLIGHT Photos. 45 L2 i
