PurePower turbofan engine gets Mitsubishi Regional Jet type certification

Mitsubishi Heavy Industries, Ltd. (MHI), Mitsubishi Aircraft Corporation and Pratt & Whitney, a division of United Technologies Corp. (NYSE: UTX), have announced that Pratt & Whitney´s PurePower Geared Turbofan PW1200G engine has acquired type certification from the Federal Aviation Administration (FAA) of United States, the company said.

This comes on the heels of the fourth Mitsubishi Regional Jet (MRJ) Flight Test Aircraft arriving in the Moses Lake Flight Test Center supporting a busy 2017 of testing and milestones, including completion of initial cold and hot soak and natural icing tests.

The MRJ-70 and MRJ-90 will each be powered by two PW1200G engines. The engine was optimized specifically for the MRJ program, which in turn designed the wing and aerodynamics with the PW1200G in mind.

The engines´ advanced technology will contribute to a 10-20% reduction in operating costs compared to the current generation of regional aircraft and 50% lower in regulated emissions, enabling the MRJ to offer best-in-class efficiency and environmental performance.

More than 15 critical engine system level certification tests were successfully completed to meet FAA certification requirements. These captured required data for certification including performance, stress, endurance, emissions, acoustics, bird impact, and fan blade containment.

The engine has accumulated more than 6,000 hours and 15,000 cycles as part of development, certification and flight testing activities. The engine provides 17,000 pounds of thrust and is currently powering five flight test vehicles.

Pratt & Whitney provides design, manufacture and service of aircraft engines and auxiliary power units. United Technologies Corp., based in Farmington, Connecticut, provides high-technology systems and services to the building and aerospace industries.

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