Abstract

To minimize collateral damage and improve the long-range accuracy of artillery munitions. One strategy is to install low-cost guidance kits to enable uncontrolled munitions to have corrective capabilities. The projectile is often stabilized by a high spin rate, which induces complex dynamic characteristics and increases the difficulty of adding control mechanisms. This paper focuses on a high-spin projectile with a tail control concept, investigates the guided boattail control mechanism, and formulates a generalized dynamic model for pulse control. Numerical simulation of the ballistic characteristics of the tail control of high-spin projectiles and analysis of the influence of control input parameters on control authority. The results show that the tail control mechanism corrected the center-of-mass motion of the projectile while generating complex angular motion. The impulse size and activation time of the pulse control significantly impact the control authority and the total angle of attack amplitude. The control input parameters can be adjusted to improve ballistic characteristics and increase control authority while ensuring stable flight of the projectile.
