EAST HARTFORD, Conn., Sept. 28, 2011 - Today, Pratt & Whitney, Japan Aero Engines Corporation (JAEC) and MTU Aero Engines AG announced they will collaborate to provide the PurePower PW1100G-JM engine for the A320neo program. Pratt & Whitney is a division of United Technologies Corp. (NYSE:UTX).

"We have been long-standing partners with JAEC and MTU in International Aero Engines' (IAE) V2500 program. The three parties plan to build upon their successful experience in the current IAE V2500 collaboration to help shape their new alliance," said Todd Kallman, president, Commercial Engines & Global Services for Pratt & Whitney. "We have reached an agreement with JAEC and MTU to join Pratt & Whitney's already launched PW1100G engine program for Airbus' newest aircraft program and added the "JM" designation recognizing JAEC and MTU on formally joining this PurePower engine program."

Under the collaboration agreement, MTU will hold an 18 percent share and be responsible for the low pressure turbine (LPT) and participate jointly with Pratt & Whitney in the high pressure compressor (HPC). JAEC will hold a 23 percent share and be responsible for the fan, low pressure compressor (LPC) and combustor/diffuser. Pratt & Whitney will be responsible for the remainder of the engine and systems integration.

The PurePower PW1000G series engines use an advanced gear system allowing the engine's fan to operate at a different speed than the low-pressure compressor and turbine. The combination of the gear system and an all-new advanced core deliver double-digit improvements in fuel efficiency, environmental emissions and noise.
