GTN says:
RR with the 3 shaft design has captured nearly half of all large turbofan sales and almost seen of Pratt from this arena which has had to team up with once great rival GE to form GENx for the A380 and 787.
Well, not quite. While Pratt is but a mere shadow of its former dominance in the commercial engine market, the joint venture w/GE is called a GP7200 - and its only application is the A380.
The GENx is GE's own standalone project, and its applications are the 787 and the 747-8. Early on, it was also offered on the A350 - but when the mega-A350 came along, GE chose not to grow the engine that much, so it's off the Airbus table now.
And the CF6 is still in production after 38 years or so; they must be doing something right to still attract customers.
