Aerodynamic airfoils and their applications

This work focuses on aerodynamic airfoils and their application. The significant aim of this work is to introduce and analyse different types of airfoils and their importance. The first part of the paper examines aerodynamic characteristics, airfoil geometry and brings the historical evolution of certain types of airfoils. The second part of the paper considers different databases, and closely examines the NACA database and its numerical labelling by looking at digit series label, which follows the acronym NACA, indicating the airfoil's shape. The main body of the paperillustrates the real-life application of chosen airfoils by examining horizontal and vertical stabilisers and wind turbines. The last part of the paperpresents the analysis of the application of chosen wing root and wingtip airfoils.
