Abstract
The frequent occurrence of control surface vibration has become one of the key problems affecting aircraft safety. The source of the freeplay of the control surface is studied, and a measurement device is developed. A nonlinear flutter analysis method under trimmed flight condition is proposed based on the discrete state-space method. Consequently, the effects of center-type freeplay and the freeplay with preload on flutter characteristics are analyzed, and the effects of preload on nonlinear flutter are verified by wind tunnel tests of a single wing model.
