The field of artillery must meet ever more stringent operational needs in the delivery of precise effects. Closely connected to meet these needs for the Canadian Forces, DRDC Valcartier studies solutions of guidance and control. DRDC Valcartier undertook to compare different suites of tools to predict the trajectory of projectiles in order to study the various concepts with a sufficient degree of confidence. Two reference projectiles were studied, namely, the Basic Finner and a 105 mm spin stabilized projectile. The MMCL (Munition Model Component Library) was benchmarked against PRODAS trajectory module using the aerodynamic coefficients predicted by PRODAS for the 105 mm configuration. Then, the MMCL package was validated using a spin-stabilized projectile. Then, trajectories of the reference model were simulated and compared for PRODAS and the MMCL. Finally, the trajectories obtained were compared with available experimental data. The results indicate that Missile Datcom generated aerodynamic coefficients are sufficiently accurate to predict the overall trajectories of the projectiles. |
