Guided projectile is one which is usually directed approximately towards the target and subsequently receives steering command from the guidance and control system to improve its accuracy. Exhaustive wind tunnel tests were conducted for various projectiles, at different angles of attack as well as Mach number. The data procured from the experiments about the balance center was processed to wind axes about center of gravity of the projectiles. A comparative study of different projectile configurations was carried out which helps in selecting the optimal configuration. The aerodynamic behavior of various projectile models were analytically modeled and compared with experimental results. The rigid body equations of motion of the projectile were developed and solved in the time domain to estimate the trajectories of various projectile configurations.
