Abstract
The lateral acceleration requirement of a "hit-to-kill" terminally-guided sub-munition (TGSM) aimed at hitting tanks near the top is examined. An analytic development of proportional navigation against stationary targets shows that a TGSM flying level at 150 m above the ground can hit a target 150 m in front of it with near vertical impact and without acceleration saturation if it can pull an initial 13.6 g. With acceleration saturation, a hit is theoretically possible with 6.8 g. TGSM configurations capable of hitting stationary and moving targets are then defined and tested with a nonlinear 6-DOF computer simulation. The footprint of a selected configuration is provided. It is observed that the 10-g configuration is sufficient to hit most stationary and moving tanks likely to be found on the battlefield with impact angles above 60 degrees and reasonable angles of attack.
