On the distribution of lift along the span of an airfoil with displaced ailerons
This 1924 technical report from the NASA Technical Reports Server, compiled from aeronautical research of the era, treats how lift is distributed across a wing span when ailerons are deflected, aimed at engineers and aerodynamicists. Its one picture is a set of line diagrams: a semicircular span with the aileron positions marked by angle and dimension, and three lift curves compared under beta equals 30 and 60 degree deflections, offering designers a clear model of how control surfaces shape a wing's load profile.
