Wind-tunnel research comparing lateral control devices, particularly at high angles of attack III : ordinary ailerons rigged up 10 degrees when neutral
A 1933 NASA technical report of wind-tunnel tests on lateral control devices, specifically ordinary ailerons rigged up 10 degrees when neutral, issued as part of a series on high angle-of-attack behaviour. The pictures are engineering charts and drawings: yawing and rolling moment curves plotted against aileron deflection, a lift coefficient graph, aileron section outlines with dimensions, and schematic diagrams of up-and-down aileron linkage positions, all in plain black line on white with grid lines and labels, offering a designer reference for simple technical diagram layouts and axis-based data graphics.
