Wind tunnel pressure distribution tests on a series of biplane wing models Part II : effects of changes in decalage, dihedral, sweepback and overhang
This is a 1929 NACA technical report from the NASA Technical Reports Server, a wind tunnel study of pressure distribution on biplane wing models, written for aeronautical engineers and researchers. Its pictures are plain engineering line graphs of normal force coefficient plotted against angle of attack from about -10 to 90 degrees, with multiple curves for varied dihedral, decalage and overhang, offering a designer little beyond the rhythm of hand-plotted data curves and gridded axes.
