Although not a new concept, the idea of rebranding Pratt & Whitney’s PW1100G geared turbofan for the Airbus A320NEO as an International Aero Engine (IAE) product is gaining momentum.

The possible move was discussed at Saturday’s meeting of the joint venture’s board here, although no decision was taken, says IAE President Jon Beatty.

But speaking to Aviation Week after signing a contract with Spirit Airlines for both IAE V2500 and PW1100G engines for A320s, P&W President David Hess said the details of how the two programs could be combined are being worked on.

“We don’t want two agreements,” he said.

Since Pratt completed its acquisition of Rolls-Royce’s 32.5% stake in IAE in 2012 for $1.5 billion, subsequently redistributing 5 percentage points to MTU Aero Engines, the venture has been owned 61% by Pratt, 16% by MTU and 23% by Japan Aero Engines Corp. (JAEC).

JAEC’s and MTU’s shares in the PW1100G-JM program, meanwhile, “are very similar,” says Hess.

Sales and marketing for both engine programs have been combined since November 2012, to present “a single face to the customer,” says Beatty. “With the same shareholders in both programs, it is an opportunity to look at more collaboration.”

Hess agrees that IAE is the appropriate brand for the PW1100G on the A320NEO, while Pratt’s own PurePower brand for the GTF family is now firmly established with engines on the Bombardier CSeries, Embraer E-Jet E2, Mitusbishi MRJ and Irkut MC-21.

While V2500 production is expected to wind down in favor of the PW1100G after 2018, by which time some 8,000 engines will have been delivered, the IAE partners have renewed their collaboration agreement to 2045. “We can’t imagine anything but continuing,” says Beatty.
