Abstract

A rotor (10) for use in a gas turbine engine (110) includes a wheel (12) and a plurality of blades (16). The wheel (12) is arranged about an axis of the gas turbine engine for rotation. The plurality of blades (16) are arranged around the wheel and extend radially outward from the wheel to interact with gases flowing through the engine. A first blade (16) comprises a first material and has a first external surface (22), a second external surface (24) opposite the first external surface to define a leading edge (32), a trailing edge (34), a pressure side (36), and a suction side (38) of the first blade, a first hole (42) extending through the first external surface and into the first blade in a direction normal to the first external surface; whereby a first plug (18) is located in the first hole and has a first outer surface (50) flush with the first external surface of the first blade such that the first outer surface is exposed to the gases surrounding the rotor, and the first plug comprises a second material that is different than the first material of the first blade.
