Abstract: Ever-increasing demands for accuracy and range in modern warfare have expedited the optimization of projectile design. The crux of projectile design lies in the understanding of its aerodynamic properties early in the design phase. In this research first investigated the aerodynamic properties of a standard M549, 155mm projectile. Aerodynamic data from wind tunnel and range testing was benchmarked against aerodynamic prediction and semi empirical design codes like MCDRAG, NSWCAP and Aero-Prediction. Further we deal with the prediction of drag by benchmarking the results of standard M549 projectile design and the predicting the boat tail angle effect for different drag coefficient. The detailed study is done and validated to reduce drag and see its effect on the projectile design for both transonic and supersonic speeds.
