14 commonly used airfoils and 10 N.A.C.A. airfoils tested in N.A.C.A. variable-density wind tunnel at Reynolds Number of 3,000,000; data for structural design in inverted flight; for airfoils of given thickness, ratio minus coefficient of lift maximum over plus coefficient of lift maximum decreases as mean camber increases; for airfoils of given mean camber, ratio tends to increase as thickness increases.
