Abstract:

This report presents mass density measurements performed in the wake of hypersonic cones in free flight using the electron beam fluorescence probe technique. The radial and axial mass density distributions were obtained in the wake of sharp nose cones with vertex angles of 44 deg and 20 deg launched at 15, 500 fps in a nitrogen atmosphere at 10 torr. The corresponding temperature distributions were inferred from the density data by assuming that the wake is isobaric and that the perfect gas law is valid a short distance behind the model.
