JF-17 Thunder Block 2 with Canards

 

Another Jf-17 with canard modification. Posted an earlier here. Canard is the French word for duck. Some of the early canard designs bore a strange resemblance to their namesakes. Oddly enough, canard in English means a gross exaggeration or hyperbole.

Advantages of Canards : 

Advantages:

• Possibility for very good stalling characteristics without elevator stops.
  
  
• Sometimes a desirable layout from the packaging standpoint: Main wing carry-through behind cabin, pusher engine installation simplified.
  
  
• Synergistic use of winglets for directional stability.
  
  
• In certain cases a simplified control linkage is possible.
  
  
• When wing flaps are not desired (for simplicity as in ultralights, or competition rules as with standard class sailplanes for example) the C_Lmax of a canard may exceed that of an aft-tail airplane.
  
  
• For unstable aircraft, canard designs may have a C_Lmax and/or drag advantage.
  
  
• Control authority is larger for unstable canard aircraft at high C_L than for unstable aft-tail designs.
