This analysis uses static and dynamic free-oscillation simulations to develop static and dynamic aerodynamic coecients for three configurations: the Viking, Genesis, and Mars Exploration Rover capsules. These computed coecients 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 coecients. A sensitivity analysis of the aerodynamic coecients for trajectory simulations at constant altitude is included.Read More
