A question for your aerodynamically-inclined...

Hey gents,

What's the purpose of those tiny little canards on the B-1B?

(and conversely, exactly what is the purpose of a rubber duck?) 

[deathjester]

Okey dokey, the B-1's small canards are part of an active vibration damping system for high speed low level flight, and the rubber duckie is merely there for intellectual bathtime conversations!!

[Shasper]

DJ has it right, since the crew is located far forward of the Bone's CG the ride can get bumpy so the canards were added to help dampen the vibrations & any unwanted pitching movement of the nose.

They're called LARC: Low Altitude Ride Control

Ducks are there for fun or "compansionship"....
