The effects of sweepback on the occurrence and principal characteristics of single- degree-of-freedom aileron flutter have been determined for a wing-aileron combination comprising an NACA 65-213, a equals 0.5, airfoil section normal to the quarter-chord line, and a 25-percent-chord aileron extending over the outer 50 percent of the wing span for 0, 20, 30, 40, and 50 degree angle of sweep.
