  • Method and apparatus for correcting the trajectory of a fin-stabilized, ballistic projectile using canards
    Patent number: 8933383
    Abstract: A system and method of trajectory correction includes a voice coil coupled to the projectile and providing a linear force; a linkage assembly coupled to the voice coil and comprising: a linkage shaft; a slot coupled to the linkage shaft; and a pin loosely coupled to the slot to form a first pivot point, wherein the linkage assembly converts the linear force to a torque force through the first pivot point; and a canard assembly coupled to the linkage assembly and including a canard shaft coupled to the linkage shaft to form a second pivot point; and at least one canard coupled to the canard shaft, wherein the torque force is transmitted to canard shaft by the linkage shaft, and wherein the canard shaft transmits the torque force to the canard to correct the trajectory of the projectile.
