Notes on the calculation of the minimum horizontal tail surface for airplanes equipped with wing flaps
This is an NACA technical note from 1937, issued by the National Advisory Committee for Aeronautics for aircraft engineers, on sizing the horizontal tail of airplanes fitted with wing flaps. Its pictures are engineering graphs of lift coefficient, normal-force and hinge-moment curves plotted against angle of attack and tab settings, with dashed and solid curves in black line on white grid paper, offering a designer a plain, data-driven vocabulary of technical charts.
