• Aerodynamic characteristics of an airfoil oscillating in the transonic flow between parallel walls was investigated by numerical analysis using a finite-difference method. Shock wave movement due to the oscillation of airfoil, aerodynamic instability of airfoil and the relations between them were investigated for several cases. The results obtained show that, in pitching oscillation mode, the shock wave movement is a dominant factor in aerodynamic instability, which acts as a positive damping in low reduced frequency, and acts as a main negative damping in high reduced frequency. In two-degree-of-freedom oscillation, airfoil become unstable depending on the phase-difference between these two modes, e.g., a classical type flutter exists in transonic flow between parallel walls. Further, the results obtained for the cases of pitching oscillation were compared with the experimental results. Both results were in good qualitative agreement.
