A rotor blade arrangement 100, has a damper member 106 below platform sections 103, 104 both to prevent vibration chatter between adjacent rotor blades 101, 102, and also to provide a heat radiation barrier. This heat radiation barrier within the member 106 reduces heat radiation flux within a cavity 113 so a rotor disc 108 can be kept at an acceptable operational temperature. The heat radiation feature takes the form of a shield 201 secured upon base or wing sections 204, 205 of the damper member 106. As the space between adjacent blade roots 202, 203 is irregular, the heat shield feature 201 is also irregular to ensure damping function is maintained whilst achieving a heat flux radiation barrier. |
