Comparison between trajectory models for firing table application

Abstract

Firing tables are mainly based on trajectory models such as the Point Mass model, the Modified Point Mass model or the Five Degree of Freedom model. This research investigates and provides a comparison between these models for different projectiles, such as 81 mm mortar as a fin-stabilized projectile, and 105 mm artillery and 155 mm artillery as spin-stabilized projectiles. Firstly, research was conducted to establish a comparison to identify the optimum model to generate the applicable firing table based on accuracy and time consumed during simulation time. Secondly, the research showed he process of generation firing table by using MATLAB and discussed the effect of integration step on accuracy.
