ABSTRACT:
A thrust mount (24) for passing thrust loads between a forward engine frame (16) and an aft engine mount upper fitting (34). The thrust mount includes first and second thrust links (46), (48) interconnected between the engine frame and an evener bar. A central clevis (30) extends forwardly from a forward surface (32) of the upper fitting (34). The central clevis (30) accepts a center portion (36) of the evener bar (38) and secures the evener bar therein using a rotatable connection mechanism (40). A pair of thrust lugs (42) also extends forwardly from the upper fitting. The central clevis is located between the opposed thrust lugs. Each thrust lug (42) includes slots (44) for receiving an evener bar end. The evener bar (38) further includes an aft surface (48) positioned near, though not normally contacting, the upper fitting forward surface (32). The rotatable connection mechanism (40) at the central clevis transfers thrust loads during normal operations. During failure conditions, the thrust lugs (42) are used to transfer thrust loads.
