Behavior of Static Pressure Heads at High Speeds
This is a 1938 NASA technical report on static pressure head behaviour at high speeds, issued for aeronautical engineers and researchers. The pictures are plain line drawings and graphs: nomographs with dense fanned grid lines, a gridded line chart of curves with circle markers, a free-body force diagram with labelled vectors, and an aircraft side profile with dashed sight lines. A designer could take their clean technical diagram style and sparse labelled-axis layout.
