ABSTRACT:
A rotor blade damper is provided that includes a body having a base, a tip, a first contact surface, a second contact surface, a trailing edge surface, and a leading edge surface. The trailing edge and the leading edge surfaces extend between the contact surfaces. The first contact surface, second contact surface, trailing edge surface, and leading edge surface all extend lengthwise between the base and the tip. The body includes at least one cooling aperture disposed adjacent the base, that has a diameter that is approximately equal to or greater than the width of the trailing edge surface adjacent the tip. The body tapers between the base and the tip such that a first widthwise cross-sectional area adjacent the base is greater than a second widthwise cross-sectional area adjacent the tip.
