From Aviation Week and Space Technology 2007 December
Pratt & Whitney plans to complete its emerging next-generation engine family partnership by mid-2008 amid growing signs the move could prompt International Aero Engines (IAE) to formerly embrace the geared turbofan concept.
Pratt signed up MTU for a 15% stake in the geared turbofan (GTF) and the lower thrust Pratt & Whitney Canada PWX10 business jet engine in mid-December and is eager to complete its team. Pratt says it’s in “ongoing discussions with the IAE partners.” The strongest immediate candidates include non-IAE partners Avio and Volvo Aero, both of which (along with MTU) agreed in 2005 to participate with Pratt in the research and development phases of the GTF demonstrator program.
However, Pratt continues to cite its preference to develop the GTF within IAE, possibly as part of a modified version of the existing consortium. As it stands, MTU’s 15% stake in Pratt’s new engine team is already larger than the 12% share it now holds in IAE. The other main IAE partners are Rolls-Royce and the Japanese Aero Engines Corp.—a consortium of Kawasaki, Ishikawajima-Harima and Mitsubishi Heavy Industries.
Pratt & Whitney says “International Aero Engines is our preferred channel to market for the next-generation narrow-body [737/A320 replacements]. We like the IAE franchise because it brings together the best technology of all of the partners and has a strong brand presence in the single-aisle market.
