Abstract
A gas turbine engine rotor blade includes an airfoil joined to a dovetail. The dovetail includes a shank from which extends two pairs of dovetail tangs being defined by a bifurcating slot disposed therebetween. The dovetail is configured for retention in a complementary dovetail groove in a rotor disk with the bifurcating slot remaining empty for reducing weight of the blade while transferring centrifugal loads from the blade to the rotor disk.
