The influence of lateral stability on disturbed motions of an airplane with special reference to the motions produced by gusts
This is a 1938 NASA technical report, issued by NASA's Technical Reports Server, on how lateral stability affects an airplane's disturbed motions, especially those caused by gusts, written for aeronautical engineers and researchers. The single picture is a line graph with a grid, plotting a quantity labelled phi in radians against a horizontal axis from 0 to 6, with several curves diverging, converging, and peaking. A designer may find in it a plain engineering chart style: dense square grid, labelled axes, and multiple hand-traced curves that could suit a technical or data-driven layout.
