Voisin X

The Voisin X (Voisin 10) was a French two-seat pusher biplane which was built in two versions, one fitted with a 37 mm (1.46 in) Hotchkiss cannon (Voisin X CA2), and the other as a conventional night bomber (the Voisin X BN2). Problems with the Peugeot engine in the previous Voisin VIII led to the installation of a new Renault engine of greater power and reliability, but the new aircraft was otherwise nearly identical to the VIII. Despite its obsolescence, it would make up the bulk of front line night bomber escadrilles until the end of the war.

Development

With the failure of the 1915 and 1916 bomber contests to produce any usable types to replace the Voisin V, Voisin was asked to produce an interim type pending the development of the next generation of bombers. This began with the Voisin VII which was itself an enlarged V, but was underpowered, and was soon followed by the Voisin VIII, which suffered severe reliability problems. As with the VIII, two versions were to be built, a night bomber, and an aircraft armed with a large single shot 37 mm (1.457 in) Hotchkiss cannon.

Like the previous Voisins going back to the Voisin III, the Voisin VIII had a steel tube structure to provide adequate strength, covered with aluminium sheet on the fuselage nacelle and doped fabric on the flying surfaces. The fuselage was square in section, with no attempt at reducing drag.
