The forward mount connects the engine aft fan case with the engine pylon forward structure. The forward mount is a damage tolerant design.
It 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.
