Comparison of the Aerodynamic Characteristics at Transonic Speeds of a Plane Wing and a Cambered and Twisted Wing, Both Having 45 Degrees of Sweepback and an Aspect Ratio of 6
A 1953 NACA technical report from NASA's Technical Reports Server comparing the transonic lift and pitching-moment performance of a plane swept wing against a cambered and twisted version, both with 45 degrees of sweepback and aspect ratio 6, written for aeronautical engineers. The pictures are line graphs of lift coefficient against angle of attack across Mach numbers from 0.86 to 1.08, with solid and dashed curves for the two wings, plus one pitching-moment chart; a designer might take the clean grid layouts and stepped curve families as a model for technical data visualisation.
