Developed fromAntoinette VII

Antoinette monoplanes were produced in series in France between 1909 and 1911.[1] They were based on the Antoinette VII,[2] which in turn was ultimately based on the Antoinette IV designed by Léon Levavasseur in 1908.[1]

The aircraft produced in series after the related Antoinette VIII are not easily distinguished from each other,[3] and examples are known were some aircraft were returned to the Antoinette factory for remanufacture with different sets of wings.[3] Although the earlier, numbered, Antoinette aircraft had been powered by Antoinette's own V8 engine, from October 1909 onwards, the factory began to offer the ENV V8 and a 37-kilowatt (50 hp) Gnôme rotary as options.[3] In addition to the aircraft produced in France, Albatros produced the type under license in Germany.[2]

The total number produced is unclear today.[4] Contemporary figures published in Jane's All the World's Aircraft put production at 50 examples in 1909 and 30 in 1910,[4] but other sources are far more conservative. Another comtemporary source notes the highest serial number assigned by the factory as 32 by May 1910.[4] Henri Levavasseur, the son of the designer, once stated a belief that no more than 50 had been built in total.[4]

Design

Antoinette monoplanes were a high-wing, wire-braced design of conventional layout. The fuselage was a monocoque structure, triangular in cross-section, with the pilot sitting in an open cockpit. Power was supplied by a piston engine in the nose driving a tractor propeller.
