Couzinet

France
Born in 1904 in the Vendée region of France, engineer Rene Couzinet graduated from the famed “Arts et métiers” school in Angers and began manufacturing aeroplanes in 1928 with the tri-motor monoplane Couzinet 10 Arc-en-Ciel prototype, designed for transatlantic flight.

The Couzinet 70, developed from the Couzinet 30, was also called Arc-en-Ciel and intended for Aeropostale’s transatlantic mail service to South America. After route-proving flight by Jean Mermoz in January 1933 it was extensively modified as Couzinet 71 and entered regular service in May 1934. Air Couzinet 10 of 1937 was totally unrelated twin-engined monoplane. Couzinet himself went to Brazil in the late 1930s, assisting with the development of that country’s aviation industry.

The first Paul Cornu helicopter was built in 1906 in Lisieux. The machine weighed 13.75 kg and its Buchet engine delivered a full 2 hp and drove two 2,25 m rotors. Horizontal propulsion was achieved by inclined surfaces that were placed in the downwash from the lifting propellers.

It reached an altitude of three metres and made flights of up to 20 metres.
