Chuanbo Yang. Wake-Fin Tailoring for Projectile Steering

А thesis. The University of Toledo. 2011. - 155 p.The overall goal of this dissertation is to investigate an active flow control concept, called wake-fin tailoring (WaFT), for improving the steering performance and attitude control of projectiles. The concept is based on the use of mechanical flow control actuators located at a position well upstream of the projectile’s tail. With an asymmetric deployment of the actuators, the system induces an asymmetric wake-flow that interacts with the tail fins to generate aerodynamic control forces and moments. The system can be used to provide in-flight adjustment capability, reduce dispersion and increase endgame maneuver footprint of the projectiles.
