Introduction. Limit cycle oscillation in aeroelastic system seems to be more prevalent in transonic air flow than in subsonic air flow according to Thomas et al. ().Certainly, LCO may be caused by structural nonlinearity no matter whether the air flow is transonic or not (Yang and Zhao, ), and the aerodynamic nonlinearity will lead to LCOs in transonic air flow even in the absence Cited by: 5.

The limit cycle flutter persists down to very low air densities, corresponding to altiludes ab ft, and the maximum limit-cycle-oscillation flutter amplitude does not occur at sea level.

The aeroelastic interaction of a typical transport-aircraft structure and the transonic flow exhibits two well-known phenomena: firstly, in the “transonic dip” (Tijdeman, ) the flutter speed shows a noticeable minimum between the critical Mach number where local supersonic regions occur in the flowfield and the Mach number where massive.

The heave and pitch motions of the rigid airfoil in the flutter-test set-up are modeled by a two-degree-of-freedom system as shown in Fig. The corresponding equations of motion can be written in nondimensional form as Experiments on Heave/Pitch Limit- Cycle Oscillations Vd--b.
