Generation of artillery firing tables for the L119 howitzer with base-bleed projectiles

Research papers. Journal of the Faculty Senate, Chulachomklao Royal Military Academy, Vol. 8, 2010, 127-135 р.This paper describes the process that we have performed in generating firing tables for the L119 Howitzer with base-bleed extended range projectiles. The process involves four main steps, which are determining projectile coefficients, selecting the desired trajectory model, implementing the model and verifying the generated results. In determining projectile coefficients, we employed several tools such as CFD (Computational Fluid Dynamic) and Aerolab. The model that we selected is the modified point-mass model because of its high accuracy without too much of computational requirements. We were able to complete the generation of all 13 artillery firing tables by using a regular notebook computer within half an hour. Finally, our generated firing table for the L119 Howitzer with base-bleed project was able to achieve 80-meter accuracy for a 9,500 m firing range, which is very accurate for a howitzer with extended-range projectiles.Contents:
