Abstract:
1. A method for attaching an engine core to an engine fan module that is attached to an aircraft pylon on an aircraft wing, the method comprising: attaching two translating rails to opposing sides of the engine core, wherein the translating rails are translatably attached to two suspension rails; lifting the engine core vertically using one or more lifting components attached to the pylon and the suspension rails; attaching the suspension rails to at least one of the alignment fittings and the engine fan module following lifting the engine core with the lifting components; and translating the translating rails and engine core in an aft-to-forward direction toward the engine fan module such that forward ends of the translating rails engage one or more alignment fittings fixed to or integral with the engine fan module, such that the alignment fittings cooperatively guide the translating rails at least one of horizontally, vertically, and rotationally to a final forward position in which the engine core is in a desired orientation relative to the engine fan module.
