Abstract : The ability to predict the complete set of aerodynamic performance parameters for projectile configurations has been a stated goal of the Computational Aerodynamics Branch, U.S. Army Ballistic Research Laboratory. In order to achieve this goal, predictive capabilities which utilize Navier-Stokes computational techniques have been developed and applied to an extensive number of projectile configurations. A summary of code validation efforts and applications for both spin stabilized and fin stabilized projectile configurations are described. Significant progress in the predictive capability for projectile aerodynamics has been achieved through the availability of substantial supercomputer resources and modem computational techniques. Current and future research areas of interest are described and provide an indication of computer resources and code enhancements needed to continue the progress in projectile computational aerodynamics. Projectile aerodynamics, Transonic flow, Finned projectile aerodynamics, Supersonic flow, Turbulent boundary layer.
