Abstract
A rotor arrangement for a rotor of a gas turbine includes at least one rotor disk with attachment slots for carrying rotor blades and an annular groove having an annular opening towards the outward direction; and rotor blades having an airfoil and a blade root and assembled in an attachment slot. Each of the assembled blade roots have a root extension with a root groove. The root groove faces the annular groove when the rotor blade is assembled in the attachment slot. For each assembled rotor blade a locking element is provided, the locking element engaging the annular groove of the rotor disk and the root groove of the respective rotor blade. Preferably all locking elements are embodied as a locking sheet metal strip, which has two bended tongues embracing the respective root extension.
