Abstract
A rotor stage of a gas turbine engine includes a platform from which rotor blades extend. The platform is provided with a circumferentially extending damper ring, the damper ring having an engagement surface that engages with the platform. The damper ring provides damping through slip between the engagement surface and the platform. The damper ring has a hoop stress that results in a load being provided to the platform from the engagement surface. The load can be optimized in order to provide improved damping.
