Abstract

The turbine blade ring has a blade platform (7) which in the longitudinal extent is deflected at least twice over the turbine disc width and covers the blade root and blade cross section. The blade platform has at least two straight sections (7a,7b) with straight side faces (7a',7b'), and at least one deflected section (7c) which is curved twice or more and with a curved side face (7c'). A recess for a straight damping element of limited length is formed in a center straight section of the side faces, and two or more straight or curved recesses for sealing elements are formed in the adjoining straight or curved side face sections.
