Abstract
Apparatus and a method for attaching individual blades to a disc rotor of a BLISK is described. Blade blanks or preforms are gripped between adjustable jaws of a rigid frame member of a linear friction bonding machine, and are attached in a non-rotational friction bonding operation. Blade preforms may be finished to final airfoil shape in a further operation after attachment. The technique is suitable for repair work or original manufacture.
