A ROTOR ARRANGEMENT FOR A ROTOR OF A GAS TURBINE

The invention relates to a rotor arrangement (RA) comprising a rotor arrangement (RA) for a rotor of a gas turbine, comprising- at least one rotor disk (RD) comprising attachment slots for carrying rotor blades (RB) andan annular groove (AG) having an annular opening towards the outward direction and- rotor blades (RB) having an airfoil (AF) and a blade root (BR) and assembled in an attachment slot (AS),wherein each of the assembled blade roots (BR) comprises a root extension (RE) with a root groove (RG), said root groove (RG) facing the annular groove (AG) when the rotor blade (RB) is assembled in the attachment slot (AS), andwherein for each assembled rotor blade (RB) a locking element is provided, the locking element engaging the annular groove (AG) of the rotor disk (RD) and the root groove (RG) of the respective rotor blade (RB). For the provision of a light and an easy mountable locking element, preferably all locking elements are embodied as a locking sheet metal strip (LSMS), which comprises two bended tongues (BT) embracing the respective root extension (RE).
