Berthaud

   The name of the designer Berthaud is better-known in connection with the automobile firm of Prini-Berthaud in Lyon. But in collaboration with Prini, Moreau, and Wroblesky-Salvez, he achieved some aeronautic success as well, particularly in metal construction. With Prini, he designed a 2-cylinder inline 2-cycle engine in 1910-1911, a year after they had built the Prini-Berthaud biplane.

   Prini-Berthaud: This 1908 design was clearly a Wright copy and probably an unsuccessful one, judging by its nearly flat and inverted airfoil and its heavy all-steel frame. There was no forward outrigger: instead, a low elevator was fitted below the rudder at the rear of the long fuselage formed by elliptical skids. Ailerons were mounted between the outer wing panels. Pusher propellers, Wright-style, were driven by an odd semi-radial 3-cylinder water-cooled Anzani. The pilot sat in front of a large radiator at the left of the motor.
