A Computational Fluid Dynamics analysis of the dynamics of probe and capsule shapes at supersonic flight conditions is performed using an automated, inviscid Cartesian-mesh scheme. This analysis uses static and dynamic free-oscillation simulations to develop static and dynamic aerodynamic coefficients for three configurations: the Viking, Genesis, and Mars Exploration Rover capsules. These computed coefficients are compared against data reduced from ballistic-range free-flight testing. A comparison of data reduction methods for capsule shapes from computational simulations and range data is included. Free-flight simulations agree well with available flight data for both fully-coupled simulations and aerodynamic database fly-throughs based on the developed aerodynamic coefficients. A sensitivity analysis of the aerodynamic coefficients for trajectory simulations at constant altitude is included. Copyright © 2007 by the American Institute of Aeronautics and Astronautics, Inc.
