Embraer E-Jets Switch to Pratt & Whitney Engines

Embraer announced that Pratt & Whitney´s PurePower Geared Turbofan engines have been selected for its future, second generation of E-Jets, with entry into service planned for 2018. The decision is an important milestone in the program, which is expected to be officially launched later this year.

The new engines – the PW1700G and PW1900G – range in thrust from 15,000 to 22,000 pounds. In combination with new aerodynamically advanced wings, state-of-the-art full fly-by-wire flight controls and other systems evolutions, they will result in double digit improvements in fuel burn, maintenance costs, emissions and external noise.

Pratt & Whitney’s PurePower engine uses 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 delivers double-digit improvements in fuel efficiency and environmental emissions as well as a 50 percent reduction in noise.

Pratt & Whitney PurePower Engine

To date, Pratt & Whitney has completed more than 4,200 hours and 12,400 cycles of full engine testing for the PurePower engine family, demonstrating the benefits and reliability of the engine architecture.

Pratt & Whitney PurePower Geared Turbofan engines (PW1000G) have also been selected for Airbus A320neo, Bombardier CSeries, Mitsubishi Regional Jet and Irkut MS-21.
Currently all first generation Embraer E-Jets have been powered by General Electric (GE) engines.

The second generation of E-Jets will be a significant step in Embraer´s commitment to continuously invest in this line of commercial jets, complementing a series of ongoing improvements currently being implemented in the existing family, with great benefits to its customers. Embraer´s objective is to offer the best product and maintain its leadership in the 70 to 120 seat market.

To date, more than 900 E-Jets are in service. Today, 63 customers from 43 countries are flying or will soon take delivery of Embraer E-Jets.
