Numerical Study on the Aerodynamic Characteristics of a Wings-Stabilized Moving Projectile
摘要
This paper presents a numerical investigation of the aerodynamic characteristics of a wing-stabilized projectile. The k-ϵ turbulence model is employed to describe the turbulent flow, enabling the calculation of drag forces and moments acting on the projectile during its motion. A rotating mesh model, combined with a sliding mesh technique, is used to simulate the rotating wings. Initially, grid convergence and grid size are examined to ensure sufficient resolution for the simulations. The simulation results are validated against experimental measurements using the ANSYS Fluent software. Subsequently, the dynamic characteristics of the wing-stabilized projectile, including drag forces, moments, pressure fields, and velocity distributions, are specifically analyzed. The findings provide a foundation for predicting and calculating the motion parameters of the projectile during flight.
