ABSTRACT:
A frame for a gas turbine engine includes an outer casing, an inner hub, and a plurality of circumferentially spaced apart struts extending radially therebetween. Each strut includes first and second sidewalls defining a radial passage therein, and an elongate damper is disposed in respective ones of the strut passages. Each damper is disposed in an interference fit laterally between the first and second sidewalls for maintaining contact therewith for effecting sliding friction to dampen vibration of the struts.
