Keywords: transonic flow, transonic flutter, limit cycle, static divergence, energy transfer

The transonic flutter boundary drops because of the pronounced effect of compressibility. An attempt to understand the transonic dip through energy concepts is made. Single degree of freedom flutter dominates the bottom of the transonic dip suggesting energy pumping mechanism as the unsteady shock motion.
