** ON A/C NOT FOR ALL The engine/pylon connection is achieved by means of a two-mount system :
Mounts- The forward mount is a damage-tolerant design consisting of a two-piece beam, single piece cross beam, and two links which attach to the pylon and aft fan case. Attached to the beam are two links which are attached to the engine attach brackets. These brackets attach to the engine fan case.
- The aft mount is a damage-tolerant design consisting of a two-piece cross beam, that attaches to the pylon. From this beam, there are three, three-piece links which attach to the engine rear frame .
2. System Description
The engine mounts are designed for side, vertical, thrust and torque loads. The damage-tolerant assemblies consist of links and beams with swaged-in spherical bearings on the ends. The link and beam assemblies are bolted to the engine at the engine fan case and turbine rear frame mount, and interface with the pylon. Additional locking and retaining features are provided on the bolts, or pins, at structural attachment points.
The engine mount design provides dual load paths to ensure safe operation should one member fail.
