Patent ID: 7856825

Claim:
A mounting system for an annular internal fuel manifold disposed within a gas generator case of a gas turbine engine, the mounting system comprising at least one fastener support assembly and at least one receiving element, one of the fastener support assembly and the receiving element being engaged to the internal fuel manifold and the other of the fastener support assembly and the receiving element being engaged to the gas generator case, each fastener support assembly including a primary fastener and a secondary fastener, the primary fastener engaging the receiving element to constrain a relative movement between the fuel manifold and the gas generator case in an axial direction while allowing the relative movement in a radial direction, the secondary fastener being in position to passively and automatically engage the receiving element in the event of failure of the primary fastener, to constrain the relative movement in the axial direction while allowing the relative movement in the radial direction, and wherein the primary and secondary fasteners include radially extending concentric pins comprising a secondary pin disposed within a primary pin and extending the length thereof, and the receiving element includes a lug defining an aligned opening receiving inner ends of both the primary and secondary pins, the concentric primary and secondary pins being slideable relative to each other along a longitudinal axis of the pins.
