ABSTRACT:
Rotor parts, such as blades, are locked in axially extending slots in a rotor by locking members positioned in circumferentially extending slots extending between and intersecting the axially extending slots. The locking members are slidably positionable into the circumferentially extending slots and displaceable between a release position and a locking position where they hold the rotor parts within the axially extending slots. A retaining element is in operative association with the locking member for securing it in the locking position. The locking members have ridges which seat against corresponding ridges formed in the circumferentially extending slots for retaining the locking members within the slots. In the locking position, the locking elements form a closure for the opening through the rotor surface into the circumferentially extending slots so that a completely smooth surface is presented on the surface of the rotor.
