A damper seal 7, 21, 31 is provided in order to act within a mounting platform structure 3 for turbine blades 1, 2 . The damper seal 7, 21, 31 includes an entrant surface 8, 28, 38 incorporating a number of paths 22, 32 to enable coolant flow across the entrant surface 8, 28, 38 . The damper seal 7, 21, 31 acts to plug an aperture 9 in the structure 3 between adjacent blades 1, 2 and damper detrimental vibrations in the structure 3 which could damage the blades 1, 2 . Thus, whilst contact portions 23, 33 are in vibrational coupling contact with the aperture 9 , coolant airflow through the paths 22, 32 enables cooling of the seal 7, 21, 31 and areas of the structure 3 about the aperture 9.
