Abstract
A slow rolling projectile comprises a projectile body has a forward section and a rear section and having a longitudinal axis. Two or more canards in the forward section are capable of being extended from and retracted into the projectile body at predetermined frequencies and/or for predetermined times. Two or more tail fins in the rear section are fixed coextensive to or at an angle to the longitudinal axis, and an actuator extends and retracts the canards. The canards are capable of being extended and retracted at a rate based on the rotation of the projectile sufficient to correct for lateral movement. A GPS or INS navigational system activates an actuator to extend and retract the canards.
Claims9
A projectile comprising:
- a projectile body having a forward section and a rear section and having a longitudinal axis;
- two or more canards in the forward section on opposite sides of the projectile that are capable of being extended from and retracted into the projectile body for times and at frequencies corresponding to the rate of rotation of the projectile;
- two or more tail fins in the rear section that are fixed coextensive to or at an angle to the longitudinal axis, and
- an actuator for extending and retracting the canards,
- wherein, after the projectile is fired along a path, the canards are extended from and retracted into the projectile body for times and frequencies related to rotation of the projectile to correct the path of the projectile.
