Abstract
A method of assembling a rotor assembly is provided. The method comprises forming at least one channel in a dovetail portion of at least one rotor blade assembly, wherein the rotor blade assembly includes an airfoil extending outwardly from the dovetail portion, inserting a sealing assembly within the at least one channel of the dovetail portion, and coupling the at least one rotor blade assembly to a rotor disk using the dovetail portion such that at least a portion of the sealing assembly is between the dovetail portion and the rotor disk.
