This paper performs a drag breakdown of an airfoil and a wing by using the exergetic method. The resulting exergetic drag curves are proposed as additional characteristic curves for external aerodynamic assessment of airfoils or any other bodies. Moreover, a new far-field wave anergy extraction method suitable for wind tunnel applications is presented. Computational fluid dynamics analyses of a NACA 0012 airfoil and a rectangular wing at subsonic and transonic conditions were used as test cases to present the concept. This new approach brings a deeper understanding of the aerodynamic behavior of a body and provides an alternative point of view to the classical near-field-based and far-field-based drag curves.
