An Investigation of Airplane Landing Speeds
A 1930 NACA technical note, published by NASA through its Technical Reports Server, presenting an investigation of airplane landing speeds for aeronautical engineers and researchers. Its single picture is a plain line graph of lift coefficient against angle of attack for a Vought VE-7 aircraft, drawn in black ink on a grid with a rising straight line that peaks near 14 degrees before dropping. A designer might take from it the clean, minimal grid-and-line style of mid-century engineering charts.
