Armand Dufaux Dufaux 4

සාරාංශය

The Dufaux 4 was an experimental aircraft built in Switzerland in 1909 and which was originally constructed as an unnamed biplane, the third aircraft constructed by the brothers Armand and Henri Dufaux. The aircraft was entirely conventional for the era - a two-bay biplane with unstaggered wings of equal span and a triangular-section fuselage. Construction began in mid-September 1909 and work proceeded rapidly, as the brothers hoped to claim a CHF 1,000 prize put up by the Automobile Club de Suisse for the first Swiss-built aircraft to fly a 1 km closed-circuit.
