A control surface actuation system has the ability to move aerodynamic control surfaces using a rotational motion of a motor. In an arrangement, rotational motion of the motor enables the aerodynamic control surfaces of a rotating projectile to oscillate and thus vary the angle of the control surfaces as the projectile spins. The rotation of a motor in one direction in combination with a gear and a link and a crank arm attached to a shaft of the aerodynamic control surfaces allows the control surfaces to move in fluttering motion to induce the maneuverin...
What is claimed is: 1. A projectile comprising: a body configured to spin about a projectile longitudinal axis during flight along a flight path; an aerodynamic device coupled to a shaft carried by the body; a crank coupled to the shaft, a general back and forth motion of the crank causing an oscillating motion of the shaft and the aerodynamic device; a motor; a drive arrangement interposed between the crank and the motor for translating unidirectional rotational motion of the motor into generally limited oscillating, back-and-forth motion of the crank ...
