Abstract:

A mathematical model developed for digital gunfire control using the NSWCDL effective drag functions was modified. the NSWCDL functions were replaced with fourth-order Rungs-Kutta numerical integration of particle trajectory equations for calculation of gun elevation angle, projectile deflection, and projectile time of flight. Projectile drag coefficient is obtained during the integration process by table look-up of prestored values. The sequence of computations is given for the present position, prediction, ballistics and gun order sections of the model. The current version of the modified model was designed not for use in a gunfire control system but as a tool for evaluation of gunfire control models.
