Abstract
The factors in bullet’s shape design which affect the drag force of bullets are important in aerodynamics, especially in ballistics. In this paper, based on traditional researches about different bullet shape designs, nose cone design of the bullet is mainly discussed, as well as the hollow tip and the rifling on the appearance of the bullet are also included. This paper adopts Fusion 360 and Ansys fluent to calculate and model. This research verifies the similarity of the drag coefficient of different bullet shape design at a low speed and figures out the best shape characteristic coefficient in Haack series design, while some problems still exists in the influence of hollow tips of the bullet to the drag force.
