Claim 8:
9. An exhaust diffuser comprising:
an inner shell;
an outer shell radially spaced apart from the inner shell such that an exhaust flow passage is defined therebetween;
one or more struts disposed within the exhaust flow passage and extending between the inner shell and the outer shell; and
an auxiliary airfoil coupled to each strut of the one or more struts, the auxiliary airfoil comprising:
a leading edge;
a trailing edge;
a first side wall and a second side wall extending between the leading edge and the trailing edge, the first side wall and the second side wall defining an interior of the auxiliary airfoil; and
a vibrational damping assembly disposed in the interior of the auxiliary airfoil and coupled to one of the first side wall or the second side wall, the vibrational damping assembly comprising:
at least one pin coupled to the auxiliary airfoil, the at least one pin having a pin body and a disk coupled to the pin body; and
at least one plate disposed between the disk and the auxiliary airfoil, wherein the at least one plate is movable between the disk and the auxiliary airfoil relative to the at least one pin and relative to the auxiliary airfoil to dampen vibrations experienced by the auxiliary airfoil.
