Abstract
An apparatus for correcting the terminal portion of the ballistic trajectory of a projectile. The projectile is initially fired at a target in a manner to cause the projectile to rotate in flight. At least one detector is mounted on a front surface of the rotating projectile to rotate with the projectile and scan the target area in a spiral pattern. A laser beam is directed to hit the target and a reflected portion of the beam energizes the scanning detector. The energized detector transmits an ignition signal to activate a trajectory correction motor and an associated nozzle having a plug that is weakened in response to the signal. The activated motor operates during the terminal portion of the trajectory to generate a thrust pulse that is passed through the nozzle having the weakened plug. The thrust pulse is directed by the nozzle to correct the trajectory of the projectile.
