Abstract
The M549 projectile has been analyzed using two different aerodynamic codes. The semi-empirical AP05 code has provided a very fast way to obtain results. The CFX code, based on the numerical solution of the full Navier-Stokes equations, took about four hours for one data point. The comparison between the AP05 and CFX computed total drag coefficient shows a difference of about 30 percent in the high subsonic range, good agreement in the transonic region, but a difference of 22 percent at M=1.2, decreasing to zero at M=3.
