Span load distribution for tapered wings with partial-span flaps
A 1937 NASA technical report from the NASA Technical Reports Server on span load distribution for tapered wings fitted with partial-span flaps, written for aeronautical engineers. Its pictures are engineering graphs of lift coefficient against percent semispan and flap span, with curves for flaps at center and at tip, plus angle of attack plots. A designer might take only the clean line-graph conventions, dashed and solid curve pairs and labelled axes, from these technical charts.
