Canard (aeronautics) 1911, few canard types would be produced for many decades. In 1914 W.E. Evans commented that "the Canard type model has practically received its death-blow so far as scientific models are concerned." Experiments continued sporadically for several decades. In 1917 de Bruyère constructed his C 1 biplane fighter, having a canard foreplane and rear-mounted pusher propellor. The C 1 was a failure. First flown in 1927, the experimental Focke-Wulf F 19 "Ente" (duck) was more successful. Two examples were built and one of them continued flying until 1931. Immediately before and during World War II several experimental canard fighters were
Canard (aeronautics) creates a vortex which attaches to the upper surface of the wing, stabilising and re-energising the airflow over the wing and delaying or preventing the stall. The canard foreplane may be fixed as on the IAI Kfir, have landing flaps as on the Saab Viggen, or be moveable and also act as a control-canard during normal flight as on the Dassault Rafale. A close-coupled canard has been shown to benefit a supersonic delta wing design which gains lift in both transonic flight (such as for supercruise) and also in low speed flight (such as take offs and landings). A free-floating
