U.S. engine manufacturer Pratt & Whitney has started FAR33 certification testing of the GTF Advantage engine – a more efficient variant of the company’s PW1100G geared turbofan.

The company continues to run extensive endurance testing to ensure product maturity at entry into service, building on more than 15 million of hours of service experience. To date, the engine has completed more than 2,000 hours of GTF Advantage development and certification testing, including a successful test on 100% sustainable aviation fuel (SAF) earlier this year.

The new engine will help reduce fuel consumption and CO2 emissions by an additional 1%, making it 17% better than the prior-generation engines. Thanks to the innovative geared fan, this GTF Advantage engine boasts improvements in terms of aerodynamics and clearance control, and it runs cooler while delivering an impressive 34,000 pounds (15,422 kg) of take-off thrust. GTF Advantage will also enable increases in payload and range, thereby unlocking more destinations for airlines. The engine is currently scheduled to become available to customers in 2024.

“GTF Advantage provides more thrust while running cooler, with more airflow and improvements in aerodynamics, coatings, and clearance control,” said Jim Pennito, vice president of A320neo family engines at Pratt & Whitney. “We’re able to do all this thanks to our revolutionary geared fan, which gives us an architecture with a long runway for the future.”

Later this year, the GTF Advantage engine will continue FAR33 certification testing on the wing of the company’s flying test bed in Mirabel, Canada. The engine will also start aircraft-level validation testing on the Airbus A320neo development aircraft in Toulouse, France.

Pratt & Whitney GTF engines have saved airlines more than 800 million gallons of fuel and more than eight million metric tons of carbon emissions to date. More than 1,300 GTF-powered planes have been delivered to 62 operators across three aircraft families: Airbus A320neo, Airbus A220, and Embraer E-Jets E2. GTF engines have powered more than four million flights, carrying more than 500 million passengers to their destinations around the world.
