Abstract

In order to study the stability of the forced projectile and the aerodynamic change of the modified projectile relative to the forced projectile after the installation of the duck rudder mechanism, the models of the common projectile and the modified projectile were established, and the aerodynamic and dynamic simulation of the two kinds of projectiles were carried out. The simulation results show that the modified projectile has enough stable reserve, the lift coefficient, the drag coefficient and the pitch moment coefficient of the modified projectile are all larger than those of the forced projectile, and the range of the modified projectile is smaller than that of the forced projectile, and the transverse deviation is increased. The correction ability of the modified projectile is studied. The ability of the correction and closeness is 1.84% and 1.9% respectively. The deviation of the left and right side changes by 105m and 114m. It has a certain reference effect on the study of the tactics for the correction of the bombshell trajectory.

Key words： two-dimensional modified bullet; rudder; simulation; correction ability
