Effect of changing the mean camber of an airfoil section
This is a 1924 aeronautical technical report from NASA's Technical Reports Server, presenting airfoil cross-section profiles and aerodynamic charts for designers and engineers studying how mean camber changes lift. The first pages show stacked airfoil outlines labelled with camber percentages and angles of incidence, drawn as clean black line profiles over dashed reference lines. The final figure is a plotted graph of lift coefficient against angle of attack with several curves. A designer could take the sparse, precise line work and the labelled sequence of curved profiles as a model for diagrammatic shape comparison.
