ABSTRACT:
An integrally bladed rotor disk, commonly referred to as an IBR or a blisk, includes partial cuts in the rotor disk extending from the rotor disk surface and along side the blades to form a partial root portion below each blade. A damaged blade can be removed from the rotor disk by breaking off the partial root portion from the disk or additionally cutting the disk to join the two cuts forming the partial root portion of the damaged blade. A replacement blade having a root already formed on the blade can then be inserted into the remaining slot of the rotor disk and secured to the rotor disk by any known means. The partial formed root of the blade can be in the shape of a dove tail root or a fir tree root.
