Kinetic Energy (KE) projectiles are major threat to armour fighting vehicles (AFVs). Penetration can be greatly reduced by detonation of a HE charge in the vicinity of the projectile. This can be greatly reduced by transferring momentum from a blast due to detonation of a High Explosive Charge in close vicinity of KE projectile. This blastwill causes a deflection on the KE projectile. The blast can cause deflection of the projectile. The study aims to investigate the effect of explosive quantity, miss distance and intercept distance on the angular deflection of free flying KE projectile. An existing analytical theory based on ideal momentum transfer is available for predicting the deflection of KE projectile using High Explosive charge. The theory is extended and used to estimate the explosive quantity, miss distance, intercept distance and time of initiation of explosive charge, for providing required deflection in KE projectile. Different combination of these parameters are simulated and a set of solutions are discussed and optimised under realistic design space.
