Abstract
By using unsteady aerodynamics method of unsteady Reynolds averaged Navier-Stokes and combining the motion equation of a structure, we established the time-domain aeroelastic analysis system to calculate the flutter speed of the configuration of a 2-D wing with three degrees of freedom and without free play. In studying the effect of free play nonlinearity on flutter characteristics, we used the description function method to solve the free play problem and determined the limit cyclic oscillation phenomenon caused by free play nonlinearity. Examining the influence of preload on the flutter characteristics showed that preload could weaken the nonlinear effect caused by free play.
