Canard (aeronautics) flown, including the Ambrosini SS.4, Curtiss-Wright XP-55 Ascender and Kyūshū J7W1 "Shinden". These were attempts at using the canard configuration to give advantages in areas such as performance, armament disposition or pilot view, but no production aircraft were completed. The Shinden was ordered into production "off the drawing board" but hostilities ceased before any other than prototypes had flown. Just after the end of World War II in Europe in 1945, what may have been the first canard designed and flown in the Soviet Union appeared as a test aircraft, the lightweight Mikoyan-Gurevich MiG-8 "Utka" (Russian for "duck"). It was
Canard (aeronautics) added to an otherwise unstable design to obtain overall static pitch stability. To achieve this stability, the change in canard lift coefficient with angle of attack (lift coefficient slope) should be less than that for the main plane. A number of factors affect this characteristic. For most airfoils, lift slope decreases at high lift coefficients. Therefore, the most common way in which pitch stability can be achieved is to increase the lift coefficient (so the wing loading) of the canard. This tends to increase the lift-induced drag of the foreplane, which may be given a high aspect ratio in order
