Fate Of International Aero Engines

Mon Aug 14, 2006 4:14 am

With Rolls-Royce and Pratt talking about making engines for the 737RS, the proposals made by Pratt and RR are different. Pratt is talking of a geared turbofan, while Rolls-Royce wants to use a three-shaft design for the 737RS engines. If IAE stays together, it will indeed be a hard decision to choose the design of the engine.

This article says that Rolls-Royce and Pratt may eventually join forces as IAE, but different proposals can split IAE up. If the 737RS uses a narrowbody design, it could become the first Boeing narrowbody to be available with three engine options (CFM, RR, and P&W). Before the 757 was unveiled, all Boeing narrowbodies used only one engine option, Pratt & Whitney. The 757 was actually supposed to have three engine options, including GE, but with the lack of interest from airlines for the GE engine, Boeing cancelled the offering.

What are your thoughts on this? Could the 737RS market support three engine manufacturers?

Absolutely. Just look at how many 737s and A320s are going to come up for replacement in the next 20 years. Certainly more than enough to support 3 engine choices.

While that may be true, I have heard by some users that offering the 777 with three engine options was a mistake (I don't know why). While the 737 and A320 have been the most successful aircraft ever, is it really worth the cost to offer three engine options? The 787, which is designed to be a 767 and A300/A330 replacement, was chosen to be offered with only two engine options. The Airbus A330 however, is offered with three engine options, and so far only 574 A330s have been sold, and will likely not surpass the 767 due to the release of the 787 and A350. Yes, I know the 767-300ER was offered with Rolls-Royce engines later in its life, but that was mostly to keep British Airways, a long-time Rolls-Royce customer, happy.
