TOKYO --- Mitsubishi Heavy Industries, Ltd. (MHI) has concluded an agreement with Pratt & Whitney (P&W) of the United States under which it will participate in a project to develop that company's new jet engine, the PurePower PW1200G, to power the Mitsubishi Regional Jet (MRJ), MHI's next-generation regional jet.

MHI will undertake development and manufacture of the new engine's combustors, high pressure turbine disks and diffuser cases as well as final engine assembly and operational testing of delivered products. These various tasks will be carried out at MHI's Nagoya Guidance & Propulsion Systems Works in Komaki City, Aichi Prefecture.

Development specimens of the combustors and diffuser cases have already been delivered from the Nagoya plant to P&W, arrangements for the tooling and equipment for the final assembly and operational testing procedures have been completed, and the engine test cell has been modified as necessary. Additionally, because final assembly must conform with P&W's technical demands pertaining to the forms of all engine parts, the Nagoya plant is currently coordinating with P&W to develop the required final assembly management system.

The PW1200G, long under development by P&W, represents the latest achievement in high-efficiency engines. Adoption of the company's proprietary "Geared Turbofan" (GTF) technology has enabled high-speed rotation of the low-pressure spool (turbine) to attain optimal efficiency, while the fan is rotated at low speed to achieve a significant reduction in noise. The new engine achieves a greater than 15% increase in fuel efficiency along with dramatically enhanced environmental performance.

MHI's track record in the development and manufacture of engines for commercial aircraft includes participation in projects relating to P&W's large-scale PW4000 jet engine, International Aero Engines' (IAE) V2500, and Rolls-Royce's TRENT 1000. In autumn 2011, the company also took part in a project involving P&W's Pure Power PW1100G-JM (for the Airbus A320 Family), which also features the GTF technology.

Through its participation in the manufacture and assembly of the PW1200G engine, MHI looks to further strengthen its international competitiveness in commercial aircraft engine technology. It also expects this initiative to give impetus to the smooth promotion of the MRJ project as well as to the new aircraft's market penetration. (ends)

The MRJ Engine Final Assembly to Be Managed in Aichi, Japan

NAGOYA, Aichi Prefecture, Japan --- The final assembly and acceptance engine test of the Pratt & Whitney PurePower PW1200G engines for the Mitsubishi Regional Jet (MRJ) will be performed by Mitsubishi Heavy Industries (MHI) Nagoya Guidance & Propulsion Systems Works located in Komaki, Aichi Prefecture in a production phase.

After the final assembly, the PW1200G engines will be transferred to MHI Nagoya Aerospace Systems Works Komaki South Plant located in Toyoyama, Aichi Prefecture. The engines will be installed on the wing at the newly constructed MRJ final assembly line located next to Nagoya Komaki Airport, where the first flight will take place.

The MRJ PurePower PW1200G engine is developed in the United States but in a production phase, since its final assembly will be conducted by MHI, both engines and the aircraft will be finished in Aichi Prefecture where the headquarters of Mitsubishi Aircraft Corporation is located.

MHI has vast experience in engine manufacturing and has been involved the in the Pratt & Whitney PW4000 engine project, International Aero Engines V2500 engine project, and also Rolls-Royce TRENT1000 project.

As MHI will be conducting final assemblies of both the airframe and engine, Mitsubishi Aircraft Corporation and MHI will be able to work closely to build a more flexible and more effective production system. The development of the engine at Pratt & Whitney is proceeding smoothly, and PW1200G engine flight test program that commenced on April 30th just completed successfully its first flight test program on June 21st.

"It is such encouraging news that the MRJ engine first flight test program completed successfully and that engine development is running smoothly," said Hideo Egawa, President, Mitsubishi Aircraft Corporation. "As we will be conducting the engine final assembly here, we are looking ahead toward the mass production of the MRJ as well as conducting flight testing on schedule."

Mitsubishi Regional Jet is a family of 70~90-seat next-generation aircraft featuring state-of-the-art aerodynamics and Pratt & Whitney's revolutionary PurePower engine to drastically reduce fuel consumption, noise, and emissions, while offering top-class operational benefits, an outstanding cabin, and large overhead bins designed for heightened passenger flying comfort.
