Abstract

A generic hypersonic vehicle configuration is studied from an in-depth computational standpoint to investigate high speed flow properties and explore future work regarding the stability properties of such a configuration. Geometries such as the Space Shuttle, X-15, ESA ixv, EXPERT, X-37b, and the HTV project are all real world examples of hypersonic configurations that utilize body flap control surfaces to maintain control authority. These projects provide the motivation for understanding the unassumingly complex state of the flow and provide a computational explanation for many of the features that are observed in experimental tests. This paper also presents quantitative comparisons against experimental surface pressure measurements and computational predictions as well as force coefficients for a large range of angles of attack.
