Wind-tunnel investigation of transonic aileron flutter of a semispan wing model with an NACA 23013 section

Perone, Angelo., Erickson, Albert L.

An investigation of aileron flutter with one degree of freedom up to 0.822 Mach number on a wing with an NACA 23013 section and the effect of wing-tip relief in alleviating aileron flutter are discussed. The beneficial effect of a low aileron-span-to-wing-span ratio is considered. The agreement that existed between the predicted and the actual flutter frequency was sufficient to indicate that sections of the type tested will not alter the existing recommendations for flutter analysis.
