Wind tunnel tests of correction formula for wings of large span
This is a 1924 NASA technical report on wind tunnel tests of a correction formula for wings of large span, compiled by the NASA Technical Reports Server from a historic aeronautics archive. The record gives little detail beyond its title, so the scans show engineering plots: lift coefficient against angle of attack, and a lift-against-drag polar curve with multiple test series. A designer could take from them the clean, sparse plotting style of early aerodynamic data, with grid lines, circled data points and labelled axes.
