Effect of wing surface contamination on aerodynamic characteristics

Abstract

The article is focused on determining the influence of wing surface contamination on aerodynamic characteristics. This work describes the description of the BL 215 airfoil on which the measurements were made, the factors affecting the change in aerodynamic characteristics, the method of obtaining the values necessary to draw a conclusion, and finally the comparison and evaluation of the resulting values. Through the geometric functions in the Inventor program, a wing model with a laminar airfoil BL 215 was created, the aerodynamic characteristics of which were calculated in the Ansys Fluent program.
