You have an interesting question about engine interchangeability.
I'll try to provide comments applicable for the CF6-50, CF6-80A and CF6-80C2
powerplant installations on Airbus and Boeing (including the former McD aircraft now under Boeing) airframes.
The below link to GE
Transportation shows the different GE
CF6-50C/C2 powerplants were used on both DC10-30 aircraft and Airbus A300B2/B4
aircraft. The differences between the Airbus and McD is in the airframer installed equipment such as the hydraulic pumps - Airbus used two pumps as two systems, while McD used two pumps as one system meaning that the plumbing, etc is different. Most of the other items are similar except for the electrical harnesses. At least one operator with both types of equipment could convert from the A300B2/B4
to/from DC10-30 in less than one shift.
2) The GE
CF6-50E/E2 powerplants were used on B747 aircraft. One operator operated both B747 and DC10-30 equipment and Boeing assisted with a conversion service bulletin to enable the subject powerplants to be used on both aircraft types.
3) The GE
CF6-80A powerplants were used on both B767-200 and A310-200 aircraft. However due to the engine configuration - engine core mounted accessory gearbox - the CF6-80A/A2 engines are limited to the B767-200 installation. The CF6-80A3 engine configuration - accessory gearbox mounted on lower fan stator case - are limited to the A310-200 equipment installation.
4) Referencing the above link, for the CF6-80C2
engine types listed there is either an "A", "B" or "D" following "C2", which designates that that engine model is for either Airbus, Boeing or Douglas. Those model designations without an "F" following the numeral following the A, B or D are PMC (power management control) engines, while those with an "F" are FADEC (full authority digital electronic control..??) engines.
Not only are their subtle differences in the engies, but the airframers equipment has to be considered.
I have been told by GE
engineers that changing a CF6-80C2
engine from PMC to FADEC can be done, but at the time they were not jumping with joy at the thought.
I am sure that their are some very creative aircraft powerplant engineers that have studied what it takes to be able to use the various engine models on several different aircraft types and some may have succeeded with the task. Remember to accomplish such a multiple use of the powerplants could require both engine and aircraft manufacturer service bulletins, maybe STC's and other legal sign offs to satisfy the FAA and other regulatory agencies.
|Quoting Gigneil (Reply 1):|
I don't believe you could swap whole engines, but I am sure they can spare parts.
Spare parts is a yes depending on model applicabilities. Thats why the former paper illustrated parts catalogs were quite thick. BTW, the IPC's are now on CD
's and/or are online.
