The pressure distribution over a modified elliptical wing tip on a biplane in flight
This is a 1931 aeronautical technical report from NASA's Technical Reports Server on pressure distribution over a modified elliptical wing tip of a biplane in flight, prepared for aeronautical engineers and researchers. The pictures are line diagrams in sequence: isometric wing plan views with pressure curves plotted along chord stations, plus a graph of rib lift coefficient against wing lift coefficient. A designer might take from them the stepped isometric layout of measured pressure peaks along a wing, shown as clean technical line work.
