Apart from the 5th Engine in the GE 90 family & lighter weight.
Supposedly to fit both the B787 & the A350.The difference being the Bleed ducts for the A350.How will that be achieved.
Will they use blanks for the Engines on the B787.Any one aware.
In the GE90 family? No. The GEnx will be lighter because they are their own family, utilizing some GE90 technology. If they were members of the GE90 family, would they not be designated GE90-67B, GE90-78A, etc? In fact (for the moment at least) they're designated GEnx-1A78 for the A350, GEnx-1B for the B787, and GEnx-2B67 for the B747-8.
