A method and ground support equipment (GSE) for attaching an engine core to an engine fan module on an aircraft pylon. The GSE may comprise GSE supports and lifting components attached to the pylon, two suspension rails attached to the lifting components, two translating rails translatably attached
A method and ground support equipment (GSE) for attaching an engine core to an engine fan module on an aircraft pylon. The GSE may comprise GSE supports and lifting components attached to the pylon, two suspension rails attached to the lifting components, two translating rails translatably attached to the two suspensions rails and fixedly attached to opposite sides of the engine core, and two alignment fittings fixed to the engine fan module. The method of using the GSE may comprise lifting the engine core vertically using the lifting components and anchoring the suspension rails to the alignment fittings. The translating rails and engine core may then be translated in an aft-to-forward direction such that portions of the translating rails engage portions of the alignment fittings to cooperatively guide the translating rails into a final forward position in which the engine core is aligned relative to the engine fan module.

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; andtranslating 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. 2. The method of claim 1, wherein the forward ends of the translating rails comprise a notch having one or more sidewalls, wherein the sidewalls include at least one beveled portion. 3. The method of claim 2, wherein the alignment fittings comprise an alignment pin which engages the sidewalls of the translating rails when the translating rails are translated in the aft-to-forward direction, thereby vertically or rotationally orienting the engine core relative to the engine fan module. 4. The method of claim 2, wherein the notch narrows in a forward-to-aft direction. 5. The method of claim 1, wherein the alignment fittings comprise a ramped portion gradually extending inward toward a center axis of the engine fan module in an aft-to-forward direction. 6. The method of claim 5, wherein the translating rails each include a beveled outer surface proximate the forward ends thereof, such that the beveled outer surface mates with the ramped portion of the alignment fittings when the translating rails are translated in the aft-to-forward direction, thereby horizontally orienting the engine core relative to the engine fan module. 7. The method of claim 1, wherein the lifting components are attached to the pylon via one or more GSE supports and wherein a vertical tilt and vertical alignment of the engine core is controlled by independent, individual actuation of each of the lifting components. 8. 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; andtranslating 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 each engage one of two alignment fittings fixed to 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,wherein the alignment fitting comprise a ramped portion gradually extending inward toward a center axis of the engine fan module in an aft-to-forward direction. 9. The method of claim 8, wherein the forward ends of the translating rails comprise a v-shaped notch. 10. The method of claim 9, wherein the alignment fittings comprise an alignment pin which engages with the v-shaped notch when the translating rails are translated in the aft-to-forward direction, thereby vertically or rotationally orienting the engine core to its final forward position. 11. The method of claim 8, wherein the translating rails each include a beveled outer surface proximate the forward ends thereof, such that the beveled outer surface mates with the ramped portion of the alignment fittings when the translating rails are translated in the aft-to-forward direction, thereby horizontally orienting the engine core relative to the engine fan module. 12. The method of claim 8, further comprising vertically tilting and aligning the engine core by independently actuating each of the lifting components. 13. 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; andtranslating 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,wherein the alignment fittings comprise a ramped portion gradually extending inward toward a center axis of the engine fan module in an aft-to-forward direction. 14. The method of claim 13, wherein the translating rails each include a beveled outer surface proximate the forward ends thereof, such that the beveled outer surface mates with the ramped portion of the alignment fittings when the translating rails are translated in the aft-to-forward direction, thereby horizontally orienting the engine core relative to the engine fan module. 15. The method of claim 13, further comprising vertically tilting and aligning the engine core by independently actuating each of the lifting components. 16. The method of claim 13, wherein the forward ends of the translating rails have a notch formed therein. 17. The method of claim 16, wherein the alignment fittings comprise an alignment pin which engages the translating rails within the notch when the translating rails are translated in the aft-to-forward direction, thereby vertically or rotationally orienting the engine core relative to the engine fan module. 18. The method of claim 16, wherein the notch narrows in a forward-to-aft direction.
