Abstract
The final goal of this study is to assess the carborundum grit type to be applied on simulated ice shapes during certification flight test. The method consists in studying the global effect of the roughness on the aerodynamic performance of an airfoil by comparing aerodynamic characteristics of an iced airfoil with penalties due to simulated ice shapes covered with different roughness grit. First, ice roughness are characterized by studying an extensive data base of ice shapes built in the CEPr wind tunnel. Then, typical rime and glaze ice shapes are formed in wind tunnel and aerodynamic performances are measured. First results in icing conditions are presented and the method for selecting the casting models and carborundum roughness type for further dry air test are discussed.
