Abstract
Recently, bladed disks with the continuous ring type structure have been used in many kinds of turbomachinery due to its high reliability. The vibration characteristics of the bladed disk with continuous ring type structure have been studied extensively, and the effect of the friction damping on the forced vibration is almost clarified. On the other hand, few studies have been done on the effect of the friction damping on the blade flutter. In this paper, the stability analysis of the bladed disk with the continuous ring type structure is carried out using the equivalent spring mass model, and the effect of the friction damping on the blade flutter is clarified.
