Abstract
An apparatus and method for controlling roll of a projectile is disclosed. The projectile includes two sections decoupled about a roll axis. The front section includes a stator and the rear section includes a rotor and a static spin imparting member. The spin rate of the projectile is controlled by utilizing the rotor and stator in combination as a generator to brake the spin or as a motor to establish spin.
