This paper describes the Design of Experiment to study the laminar­turbulent transition phenomenon on a 10° AEDC cone in Transonic­Supersonic regime. In particular, the effects of several parameters (as concentrated roughness height, roughness position, Reynolds number and Mach number) on the laminar­turbulent transition were measured. The large number of parameters that were considered, made this activity very complex and expensive to study with a typical experimental approach. As consequence, a Modern Design Of Experiment approach was adopted to develop highly efficient experiment designs yielding results to within a specified accuracy and, at the same time, saving resources in terms of costs and time consuming. A secondary objective of this activity is evaluate the correlation between infrared measurements and high frequency pressure measurements for transition analysis.

Abstract

This paper describes the Design of Experiment to study the laminar­turbulent transition phenomenon on a 10° AEDC cone in Transonic­Supersonic regime. In particular, the effects of several parameters (as concentrated roughness height, roughness position, Reynolds number and Mach number) on the laminar­turbulent transition were measured. The large number of parameters that were considered, made this activity very complex and expensive to study with a typical experimental approach. As consequence, a Modern Design Of Experiment approach was adopted to develop highly efficient experiment designs yielding results to within a specified accuracy and, at the same time, saving resources in terms of costs and time consuming. A secondary objective of this activity is evaluate the correlation between infrared measurements and high frequency pressure measurements for transition analysis.
