Blunt Cone, Hifire-1 and Hifire-5 Boundary Layer Transition

Abstract

This interim technical report summarizes technical activity on AFRL 6.1 laboratory task LRIR 15RQCOR102 during fiscal year 2017. The objective of this task is to better understand boundary layer transition in hypersonic flowfields with spanwise nonuniformity. Several advances were made under this task during FY18. The HIFiRE-1 and -5b body of ground and flight data were further analyzed, producing some general recommendations on the prediction and ground test of hypersonic boundary layer transition. As a precursor to testing transition on the spanwise nonuniform boundary layer on a cone, the transition mechanisms for blunt cones were measured in the AFRL high Reynolds Mach 6 wind tunnel. These measurements are the first of their type made in this facility.
