Spinning characteristics of wings II : rectangular Clark Y biplane cellule: 25 percent stagger; 0 degree decalage; gap/chord 1.0
This is a 1935 NASA technical report, compiled by NASA Technical Reports Server, presenting wind-tunnel test data on the spinning characteristics of a rectangular Clark Y biplane cellule with 25 percent stagger and 1.0 gap-to-chord ratio, written for aircraft engineers. Its three pages are dense engineering graphs plotting pitching-moment, rolling-moment and yawing-moment coefficients against angle of attack, sideslip and aileron-deflection ratio, drawn as thin multi-line curves on gridded paper with labelled series. A designer could borrow the orderly grid layouts and stacked small-multiple chart structure as a model for technical data visualisation.
