Abstract

In order to study aerodynamic characteristics of one-dimensional trajectory correction umbrella resistance device, a ballistic correction projectile model with umbrella resistance on standard 82 mm mortars was established in the paper. Then, the numerical simulation against the model in the subsonic case was implemented by the computational fluid dynamics software Fluent. The result shows that expansion of the resistance umbrella structure destroys streamline structure of warhead, and changes aerodynamic layout of projectile, making the resistance is bigger. The resistance coefficient ratio reaches about 2.3 before and after resistance umbrella opening. The result could help to research on one-dimensional trajectory correction projectile.

Key words： umbrella resistance device; trajectory correction projectile; aerodynamic characteristics; numerical simulation
