Abstract
A method for optimizing a design of a rotor blade which has a blade root and a blade airfoil, of a turbomachine in which an actual natural frequency of the rotor blade is detected and compared with a reference value or reference range and, if a deviation or match between the actual natural frequency and the reference value or reference range, which will impair the proper operation of the rotor blade, is identified, a structural change to the rotor blade is undertaken in order to change the natural frequency thereof, wherein as the structural change at least one cutout is formed at a predetermined position on at least one side face of the rotor blade root. A rotor blade for a turbomachine, which blade has a blade root and a blade airfoil, wherein at least one cutout is formed on at least one side face of the rotor blade root.
