Abstract: Aerodynamic predictions are performed for NASA Dual Control Missile configuration using FLUENT commercial CFD package and Engineering-level codes: Missile DATCOM, Aeroprediction, MISL3 and MISDL. In this article, engineering-level missile aerodynamic codes and CFD results on the NASA Dual-Control Missile are compared with wind tunnel data to help evaluate the capabilities of these methods. The goal is to provide sample results to illustrate those flow regimes in which alternate prediction methods produce reasonable aerodynamic characteristics, and then discuss some guidelines for the selection and use of alternate methods. Another purpose of these results is to illustrate those flow regimes which require the use of advanced CFD calculations to ensure that accurate and valid results are obtained.
