Where does the term canard come from in aeronautics?

Canard (aeronautics) A canard is an aeronautical arrangement wherein a small forewing or foreplane is placed forward of the main wing of a fixed-wing aircraft. The term “canard” may be used to describe the aircraft itself, the wing configuration, or the foreplane. The term “canard” arose from the appearance of the Santos-Dumont 14-bis of 1906,

How does a canard affect the pitch of an aircraft?

However, the canard can actually make your aircraft pitch up further. The increase in angle of attack causes both the canard and the wing to generate more lift. If the canard’s increase in lift is greater than the wing’s, the nose will pitch further up.

How much lift does a canard give an aircraft?

If your aircraft weighs 1300 lbs., and the canard generates 250 lbs. of lift to balance the aircraft, the wing only needs to generate 1050 lbs. of lift.

Why do aircraft designers use the canard configuration?

The aerodynamics of the canard configuration are complex and require careful analysis. Rather than use the conventional tailplane configuration found on most aircraft, an aircraft designer may adopt the canard configuration to reduce the main wing loading, to better control the main wing airflow,…

How are canards used in a flight control system?

Canards with little or no loading (i.e. control-canards) may be used to intentionally destabilize some combat aircraft in order to make them more manoeuvrable. The electronic flight control system uses the pitch control function of the canard foreplane to create artificial static and dynamic stability.

Which is an example of a canard foreplane?

Canard foreplanes, whether used in a canard or three-surfaceconfiguration, have important consequences for the aircraft’s longitudinal equilibrium, static and dynamic stability characteristics. The 1906 Santos-Dumont 14-bis History The Wright Flyerof 1903 was a canard biplane

Why does a canard have to be bigger than the wing?

To ensure safe pitch stability in the stall, the canard must stall first, so the wing must always stay below its maximum lift capability. Hence, the wing must be larger than otherwise necessary, reducing or even reversing the reduction in size enabled by the canard lift.
