Abstract
A system and method for controlling roll in a projectile. The novel system () includes first () and second () sections adapted to counter-rotate relative to each other and a mechanism () for inducing the counter-rotation to generate a roll torque on the projectile (). In the preferred embodiment, the mechanism () is a motor comprised of a rotor () affixed to the first section (), and the second section () which acts as a stator that rotates around the rotor () when a current is applied to the armature. In an alternative embodiment, the second section () is turned by a motor () attached to the first section () which drives a small gear engaging a full-diameter ring gear () on the second section (). In the illustrative examples, the first () and second () sections are a missile forebody and a tail section of the projectile.
