** ON A/C NOT FOR ALL The forward mount connects the engine aft fan case with the engine pylon forward structure. The forward mount is a damage tolerant design.
Forward Engine MountIt consists of :
- the support beam assembly : for pylon connection via 4 tension bolts and 2 alignment pins.
This fail-safe designed fitting is an assembly of 3 components : 2 half-fittings and 1 plate. - one bearing fitted on the support beam assembly which carries y and z loads. The outer cage is axially free in the engine aft fan frame aperture and therefore carries no x loads. In case of lateral link failure, the bearing partially carries the x loads.
- one link/beam/bracket assembly which carries the x thrust loads. The beam is hinged to the main bracket at its center.
A link is installed at each end of the beam.
A bracket attached to the engine casing supports the front of the link.
The link ends have bearings.
2. Material
The forward engine mount beam is machined from an Inconel 718 forging. The crossbeam, links and engine attach brackets are machined from 6-4 Titanium.
