Abstract

In order to predict the exterior trajectory of small caliber flat nose bullet in the process of design, based on the aerodynamics principle, a warhead resistance model of small caliber flat nose bullet was established. Then the warhead resistance model is further combined with the existing friction resistance model and the bottom resistance model to get the flight resistance model of the flat nose bullet. The resistance model and particle trajectory equations are combined and solved simultaneously. The results are compared with the experimental data. It is found that the theoretical calculation is consistent with the experimental data of the shooting range, which proves the correctness of the resistance model of the flat nose projectile.

Key words： flat nosed projectile; resistance model; exterior trajectory
