Considering the situation of the application of aerodynamic damping in the forced response

an aero-damping design method based on basic blade profile was proposed.It was revealed that a slight adjustment to the blade-stacking axis of blade can change the aero-damping

meanwhile

the effect on the fluid filed can be confined to the minimum.The relationship between the adjustment and the aero-damping was established.Owing to such a relationship

a large quantity of fluid calculations could be avoided and an improveing of the aero-damping by adjusting the stacking axis can be obtained.In this way

the shape similarity was used to connect the mode shape and aerodynamic damping.The smaller the similarity

the bigger the aero-dynamic.
