Patent ID: 7217093

Claim:
A rotor blade damper, comprising: a body having a base, a tip, a first contact surface, a second contact surface, a trailing edge surface, a leading edge surface, wherein the trailing edge and the leading edge surfaces extend between the contact surfaces, and the surfaces extend lengthwise between the base end the tip, and the body includes at least one cooling aperture disposed adjacent the base, that has a diameter that is substantially equal to or greater than the width of the trailing edge surface adjacent the tip; and wherein 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 and includes a lengthwise axis, and wherein the body tapers such that at substantially every point along the lengthwise axis the leading edge surface is greater than the trailing edge surface at that point and said rotor blade damper further comprising one or more cooling channels disposed in the first contact surface adjacent the tip.
