Design and Simulation Analysis of One-Dimension Projectile Trajectory Corrector for Mortar Shell

Article Preview

Abstract:

Combined with the special structure of mortar shell empennage, a one-dimension projectile trajectory corrector positioned at the empennage is proposed. Flow field simulation is taken in Fluent and the drag coefficient of mortar shell is calculated. The drag coefficient is fitted to get the fitting curves by using Logistic function and polynomial function. Trajectory model is established and solved, the correction capability is evaluated and the correction precision is analyzed. The simulation analysis indicates that this trajectory corrector is feasible and has obvious correction capability.
