  Canard - Wikipedia, the free encyclopedia
In aeronautics, canard (French for duck) is a type of fixed-wing aircraft in which the tailplane is ahead of the main lifting surfaces, rather than behind them as in conventional aircraft.
The canard surface normally produces positive (upwards) lift which adds to the overall lift, whereas a conventional tailplane normally produces a downforce, partially cancelling the lift from the main wings.
Deploying flaps causes a large nose-down pitching moment, but in a conventional aeroplane this effect is considerably reduced by the increased downwash on the tailplane which produces a restoring nose-up pitching moment.

 Canard
To place the canard, the lower fuselage was again precisely leveled and the canard set into position and adjusted to the correct angle of incidence.
The canard bed is now shaped so as to result in the correct angle of incidence when the canard itself is dropped into position and bolted down.
The canard cover is set in place in the fuselage and layups are made on top of the aluminum tape covered wax to form the flanges on either side of the nose.

 Nicolas Francois Canard
Canard's main contribution to economics arose as an essay submitted in 1801 to an Institut de France contest.
Echoing Cantillon and drawing an analogy with the circulation of fluids, Canard discussed how these flows need to be balanced to achieve equilibrium and how the forces of individual interest and competition operate to achieve this balance.
It is partly for this reason that mathematical economists, particularly Augustin Cournot, struggling to draw attention to their work, felt that the shadow of Canard was being used by the academic establishment to dismiss them.

 Canard (computing) - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-11-06)
In computing, Canard (French for duck) refers to "a mistaken and confused belief", as in the following example: "Although Multics was much derided at the time by its critics, history has shown these complaints to be canards."
For those unfamiliar with computer jargon, this usage can be misleading because, in English, canard connotes an intention to deceive — specifically, by spreading an absurd, overstated tale: "M.P. So-and-so again brought up the tax reduction canard in spite of the fact that taxes have actually risen".
Following the 1981 publication of Tracy Kidder's Pulitzer Prize-winning book The Soul of a New Machine (Atlantic Monthly, Boston), the term, which had been in-house slang at Data General (the manufacturer of the supermini which was the subject of the book) spread throughout the computer world.

 ASK DJ Aerotech Question
In the case of a typical canard aircraft where the wing and canard both lift upwards, the middle part of the wing (the part that makes most of the lift!) has to fly through the perpetual downdraft created by the canard.
In the case of the canard layout, the canard is supposed to stall first.
Theoretically, that is. In some canard aircraft with very low wing loadings and long wings (such as sailplanes), it's possible in a tight turn to get a big difference in airspeed between the inside wingtip and the rest of the wing.

In case of a Canard aircraft, however, pitch stability is a function of the balance between the lift generated by the main wing and the canard.
On canard aircraft, all of the induced drag is associated with generation of lift enough to support the weight of the aircraft.
On well designed canard aircraft, the canard is designed to stall before the main wing when excess angle of attack is encountered.

As Wade Langford mentionned, the canard are not used to increase lift, but they are an aircraft configuration for Delta wing airplane (whitout horizontal tails to maneuver the plane) by placing canards in front of the airplane.
Canard arrangements have interesting styling effects, and they can be made to be safe with a lot of extra effort; so they might be ok for sport airplanes and certain special purpose airplanes, but they are not recommended where the ultimate performance, efficiency, comfort, and utility are desired.
Canard design seems to be stuck in a first generation sort of situation, sort of like the way monoplanes were when they first came out.

 The Mavens' Word of the Day
Canard means 'a false story; hoax' in French, which is where the English sense directly comes from.
But the full phrase, in use since Middle French, is vendre un canard a moitie (with accents omitted), which means 'to cheat or swindle', and literally means 'to half-sell a duck', since to half-sell a duck is the same as not selling it at all.
This sense of canard is first found in English in the middle of the nineteenth century.

 canard flap location..??
In a canard aircraft it is important that the canard stall before the main wing and that the main wing go through zero lift before the canard.
The limiting factor on take-off speed and landing speed on a canard aircraft is the ability of the canard/elevator unit to reach enough lift to compensate for its considerable loading.
An all flying canard or plain flap/elevator on the canard will pitch the plane up to high angle of attack without stalling the main wing as long as the CG is set for stable flight.

 Canard-Rotor-Wing UAV   (Site not responding. Last check: 2007-11-06)
The CRW would spin a center wing to take off like a helicopter.The vehicle would then accelerate to about 120 knots when flaps would deploy from the front and rear wings.
Once the rotorcraft is at a sufficient forward velocity, the required lift generation is transferred from the rotor to a canard and horizontal tail.
Flap deployment would off load the spinning center wing, which could then stop rotation and be locked into a position across the fuselage to perform as a third wing.
