Abstract
A rotor disk assembly for a gas turbine engine includes a rotor disk with a circumferentially intermittent slot structure that extends radially outward relative to an axis of rotation. A heat shield has a multiple of radial tabs engageable with the circumferentially intermittent slot structure to provide axial retention of the cover plate to the rotor disk.
