The interdependence of profile drag and lift with Joukowski type and related airfoils
This 1935 NASA technical report, a translated aeronautical study by a NASA Technical Reports Server contributor, examines how profile drag and lift relate across Joukowski-type and related airfoil shapes, presented for aerodynamics engineers through graphs and diagrams. The pictures are plain engineering charts of lift coefficient, drag and thickness curves plus a circle-to-airfoil construction diagram, offering a designer little beyond the stark line-and-grid vocabulary of technical drawing.
