The 1910 Deperdussin monoplane was the first aircraft to be built in significant quantities by Aéroplanes Deperdussin. The type was produced in a number of variants which were flown successfully in air races and gained several records during 1911, and was used by the Australian Central Flying School at Point Cook, Victoria. Several have survived, including an airworthy example in the Shuttleworth Collection in England.
Aéroplanes Deperdussin was established in 1909 by the silk broker Armand Deperdussin with Louis Béchereau acting as the technical director. The first product of their aircraft works at Laon was a canard configuration design, which was not a success. The 1910 monoplane was their first successful design. The prototype, which was first flown by George Busson at Issy-les-Moulineaux in October 1910, possibly powered by a water-cooled inline 4-cylinder Clerget engine.
The 1910 Deperdussin monoplane was a tractor configuration mid-wing monoplane, with a very slender fuselage formed by a shallow fabric-covered wire-braced wooden box-girder, the longerons curving in to a vertical knife-edge at the back. The depth of the front section of the fuselage was increased by a shallow shell of wood veneer built over curved formers. Due to the extremely shallow fuselage, the pilot was almost completely exposed, sitting on rather than in the fuselage.
The wings were mounted below the upper longerons and were slightly tapered. Lateral control was by wing warping. In earlier aircraft the warping and bracing wires were attached to a pair of vertical kingposts just aft of the leading edge of the wing: in later aircraft these were braced by diagonal struts leading back to the fuselage longerons. The empennage of early examples consisted of an elongated triangular vertical fin with a cutout to allow elevator travel with a rectangular rudder hinged to the trailing edge, and a similarly elongated triangular tailplane with an elevator.
