Abstract
A system for controlling the attitude of a cylindrical body moving in a fluid, including controlling the attitude of this body in roll, which is applicable to controlling the roll of projectiles, rockets and missiles. The system includes a finned rotary empennage concentric with the body, a torque-transmitting means connecting the body and the empennage, and an attitude detector means mounted integral with the body. The attitude detector means produces an electrical signal which is proportional to the divergence of the actual and desired attitude of the body. This signal is amplified and applied to the torque-converting means which changes the rotation of the empennage relative to the body, to thereby correct the attitude of the body by such relative rotation and the dynamic force exerted on the fins of the empennage by the fluid in which the body is moving.
