Rotor disk assembly and lock assembly therefor

摘要

A rotor disk assembly (56) has a circumferentially intermittent slot structure (94) which engages a multiple of radial tabs (88) provided on a heat shield (52). A lock assembly (96) engages at least one opening formed by the slot structure (94) to provide an anti-rotation interface for the heat shield (52). The lock assembly (96) includes a lock body (110) with an undercut slot (110) which receives a retaining wire (102) of a polygon shape.
