Chassagny et Constantin

   At least 3 aircraft bore Chassagny's name. The first was a copy of the Demoiselle, and the second was a small monoplane advertised in 1910 as "the lightest and cheapest." The latter was designed by Constantin, who also invented devices to improve the performance of all kinds of flying machines, like his cone added to the front of the Bleriot XXIV; and his "deflecting surfaces," a kind of slots, on wing leading edges. The aeroplane was built at the Labaudie et Puthet workshops; it featured an all-covered fuselage, an air-cooled 3-cylinder Viale, a kite-shaped rudder, 2 long triangular tailplanes and a trapezoidal elevator brought up the rear. The wings warped. At the 1910 Paris Salon, the clear-doped Chassagny was sold without its engine for only 7,000F; it may have been the only one built. The pilot De Baleira crash-landed it in a yard on 12 November 1910.
   Another Chassagny resembled the Nieuport monoplanes, but with a radial engine, V-leg undercarriage with a single long central skid with wheels set at the ends of a long cross-axle. The tail unit had a comma-shaped rudder, 2 long triangular tailplanes and 2 curved elevators at the rear; the wings warped. It was powered by an Anzani radial.
