The triplane had been a feature in the mental landscape of aeronautical designers since John Stringfellow’s well known model of 1868, and this itself was based on a far more seriously designed and tested 1843 triplane of Cayley’s, which was then less familiar. Moreover, there was already a triplane flying from Issy. It was a short-span (7 1/2 m) tractor-propeller ‘three-decker’ with side curtains enclosing the mainplanes and a box-kite biplane tail with the elevator in the middle of the box and a rudder projecting behind. It had been built by the Voisin brothers to the design of Ambroise Goupy. Though the Goupy I (it was followed by an influential biplane, the Goupy II) did get off the ground for a not exactly stupendous distance, its greatest impact was that, through advance descriptions of it printed in England, it inspired the Englishman A. V. Roe to build a much more effective series of triplanes that even today, two-thirds of a century later, provide one of the immortal mascots of aeronautics; and its replica is still flying. But when the Goupy I first hopped in September 1908, no one in Britain had ever yet flown an aeroplane. On this side of the Atlantic the delivery ward was still located at Issy.

The first Goupy design was this Voisin-built triplane, variously modified along the way.

The Goupy I triplane, built by the Voisins to the design of Ambroise Goupy, had a wing-span of 7 1/2 m and a weight, including its eight-cylinder 50hp Renault engine, of 500kg. Its best performance under test in 1908 at Issy was a hop of 150m, but it inspired other designers.

THE GOUPY TRIPLANE. - General view of the Goupy triplane from the rear, showing the longitudinal girder which carries the engine in front and the box-kite tail behind. The propeller is right in front, and the pilot sits behind the engine. The tail contains a rudder, and has small steering tips outside the curtains. The span of the main planes is 7 metres, their surface 60 square metres. The weight of the whole machine is 650 kilogs., and the engine is a 50-h.p. Antoinette.
