On Waverider Aerodynamics Experimental Data Analysis Features

Abstract

The study is devoted to the investigation of the waverider experimental data interpretation. Two features affects the correct comparison opportunity. The first is the virtual and experimental model differences, i.e. the different wetted area. The second is the drag coefficient terms evaluation: pressure drag, skin friction and base drag. The skin friction calculations were performed by the flat plate correlations. The results show that skin friction plays the significant role in the overall drag within the wide Mach number range.
