axially locating a heat shield having a multiple of radial tabs which extend radially inward relative to the axis of rotation, the multiple of radial tabs axially aligned with openings defined by a circumferentially intermittent slot structure on the rotor disk;
rotating the heat shield to radially align the multiple of radial tabs with the circumferentially intermittent slot structure to axially retain the cover plate to the rotor disk; and
engaging a lock assembly that has a retaining wire that defines a polygon shape with the circumferentially intermittent slot structure to provide an anti-rotation interface for the heat shield.
15. A method as recited in claim 14, further comprising:
resiliently compressing the retaining wire of the lock assembly and inserting the compressed retaining wire into the circumferentially intermittent slot structure.
16. A method as recited in claim 14, further comprising:
spanning an interface with the heat shield.
17. A method as recited in claim 14, further comprising:
spanning a splined interface between a high pressure turbine and a high pressure compressor.
18. A rotor disk assembly for a gas turbine engine comprising:
a rotor disk defined about an axis of rotation, said rotor disk having a circumferentially intermittent slot structure that extends radially outward relative to said axis of rotation;
a component defined about said axis of rotation, said component having a multiple of radial tabs which extend radially inward relative to said axis of rotation, said multiple of radial tabs engageable with said circumferentially intermittent slot structure; and
a lock assembly comprising a resilient retaining wire that can be compressed such that said compressed resilient retaining wire can engage with at least one opening formed by said circumferentially intermittent slot structure to provide an anti-rotation interface for said component, said resilient retaining wire defining a polygon shape.
