Abstract
The present invention provides a rotor blade capable of being axially loaded in slots on a gas turbine engine rotor and particularly suited for use on turbine disks. The blade has a generally axially extending dovetail root which is effective for being loaded into a rotor disk slot between adjacent disk posts. Anti-rock tangs are disposed radially outward of the root and tangentially extend from the shank and are generally linear in the axial direction. The anti-rock tangs are effective to engage the radially outwardmost facing surfaces of the adjacent dovetail posts between which is disposed the associated dovetail slot.
