Abstract
A rotor for use in a gas turbine engine includes a wheel and a plurality of blades. The wheel is arrange about an axis of the gas turbine engine for rotation. The plurality of blades are arranged around the wheel and extend radially outward from the wheel to interact with gases flowing through the engine. One or more of the plurlaty of blades is formed to include a hole that extends into an external surface of the blade and a plug located in the first hole. The blade and the plug are made of different materials or have different densities to vary the frequency response of the blade.
