Preliminary Study of Some Factors which Affect the Stall-flutter Characteristics of Thin Wings

Abstract

Report presenting the results of an exploratory, analytical, and experimental study of some of the factors that can be important in the stall flutter of thin wings. Some of the factors considered were Mach number, Reynolds number, density, aspect ratio, sweepback, structural damping, location of torsion nodal line, and concentrated tip weights. Some of the factors were considered to be more or less significant, but all require further study.
