Patent ID: 8353672

Claim:
A turbine blade damper arrangement for providing clamping between turbine blades, the arrangement including a first, part cylindrical, contact surface, on a first circumferential side of each turbine blade, on an inner side of a turbine platform, and a second, flat, inclined contact surface, on an opposite circumferential side of each turbine blade, on the circumferential side of an adjacent turbine platform, the first contact surface being spaced from the second contact surface on an adjacent turbine blade, with a cylindrical axis of the first contact surface being substantially perpendicular to the second contact surface, and with the second contact surface being inclined away from the turbine radial direction; and an elongate damper being located between each adjacent pair of turbine blade platforms, the damper including a first, part cylindrical, engagement face engageable with the first contact surface, and a second, flat, engagement face substantially perpendicular to the axis of the first engagement face, which second engagement face is engageable with the second contact surface on an adjacent turbine blade.
