Aerodynamic Predictions for the Scorpion Parent Projectile Using a Navier-Stokes Approach

Abstract

This report documents computations which were performed to determine the aerodynamic performance of several proposed designs for the Scorpion parent projectile. These aerodynamic predictions were made using a three-dimensional parabolized Navier-Stokes technique. Using the predicted aerodynamic coefficients, trajectory simulations were performed and the pitching and swerving motion of the projectile determined. This Navier-Stokes computational technique was also applied to predict the roll characteristics of one of the selected designs. Subsequently, one of the designs was fired through an aerodynamics range allowing experimental verification of the original predictions. These comparisons are also included in this report.
