Abstract
A turbine blade damping system for a turbine includes a turbine blade platform and a damper recessable within a pocket defined by the platform. An underside of the platform defines a beveled surface. An outer side of the damper defines a complementary beveled surface. When the turbine spools up, centrifugal force acting on the damper forces it in an outward direction from the pocket toward a mating surface of an adjacent turbine blade platform.
