Abstract
A rotor blade retention assembly includes a rotor blade having a dovetail mounted in a complementary axial dovetail groove in a rotor disk. A primary blade retainer retains the blade in the groove against axial movement in a first direction. A secondary blade retainer retains the blade in the groove after a predetermined travel of the blade in the first direction upon failure of the primary blade retainer to restrain the predetermined travel.
