Wind-tunnel research comparing lateral control devices, particularly at high angles of attack V : spoilers and ailerons on rectangular wings
A 1933 NACA-style wind-tunnel report from the NASA Technical Reports Server on spoilers and ailerons as lateral control devices on rectangular wings at high angles of attack. Its pictures are engineering line graphs of rolling and yawing moment coefficients plotted against angle of attack, aileron angle and spoiler size, drawn in plain black lines with fine grid paper and labelled curves, useful to a designer for the restrained, technical chart vocabulary of early aeronautics.
