Prediction of the impact point for spin and fin stabilized projectiles

WSEAS transactions on information science and applications. Issue 12, Volume 5, 2008. – 10 p.A method for real time in flight prediction of the ground impact point of indirect fire projectiles is investigated. The projectiles is assumed to be both rigid (non-flexible), and rotationally symmetric about its spin axis launched at low and high pitch angles. A six degree of freedom projectile model solution is used to propagate the projectile state from an arbitrary point along the trajectory to the ground impact point. The projectiles manoeuvring motion depends on the most significant force and moment variations, in addition to gravity. The developed computational method gives satisfactory agreement with published data of verified experiments and computational codes on atmospheric projectile trajectory analysis for various initial firing flight conditions.
