ABSTRACT:
An improved bladed rotor structure for an axial structure for a turbine which is easy to disassemble and produces high damping. Coupling members are located between adjacent blade ends to couple adjacent blades together. Anchoring elements affix adjacent blades with the coupling members which are non-rightangular parallelogram-shaped blocks.
