Two Stage Light Gas Gun for Research on Hypervelocity Base Flows

Abstract

Hypersonic flight of projectiles at high enthalpy features a combination of fluid and thermodynamic phenomena of interest to the US Air Force that are very challenging to model, including thermo-chemical nonequilibrium, flow separation, and turbulence. We will characterize the base flow behind conical projectiles and answer key questions about the influence of thermo-chemical effects on flow turbulence using a combination of advanced imaging diagnostics. The impact of this research will be much-needed characterization of the base flow behind hypersonic projectiles at high enthalpy. In addition, we will develop a deeper fundamental understanding of the influence of aerothermochemistry on flow separation and turbulence. Finally, we will provide a wealth of validation data for simulations of hypersonic base flows both with and without active chemistry effects.
