LONDON – Engine manufacturer Pratt & Whitney today announced that it has started FAR33 certification testing of the GTF Advantage engine.

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 manufacturer has put the engine through more than 2,000 hours of development and certification testing. This includes a successful test running on 100% sustainable aviation fuel (SAF) earlier this year.

Management statements

Rick Deurloo, president of Commercial Engines at Pratt & Whitney, said: “GTF Advantage offers even more value to our customers, especially on longer-range aircraft like the A321XLR.”

“It will extend GTF’s lead as the most sustainable, fuel-efficient and powerful engine for the A320neo family – and it will be highly reliable on day one.”

Speaking on the advantages of the engine, Jim Pennito, vice president of A320neo family engines at Pratt & Whitney, stated:

“GTF Advantage provides more thrust while running cooler, with more airflow and improvements in aerodynamics, coatings and clearance control.”

“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.”

Superior & greener engine technology

The new engine not only enjoys a greener operating footprint, but also provides increased payload and range. Pratt & Whitney quote the following engine data:

The GTF Advantage engine reduces fuel consumption and CO₂ emissions by an additional 1%, making it 17% better than prior-generation engines.

With up to 34,000 pounds of take-off thrust, GTF Advantage will also enable increases in payload and range, thereby unlocking more destinations for airlines.

Testing & engine commissioning

The engine is currently scheduled to become available to customers in 2024.

In late 2022, 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 commence aircraft-level validation testing This will take place ‘on-wing’ on the Airbus A320neo development aircraft in the manufacturer’s Toulouse, France facility.

Current range of GTF engines

The Pratt & Whitney GTF is the world’s most efficient and sustainable single-aisle aircraft engine. The GTF family has lowered fuel consumption and carbon emissions up to 20 percent, compared to prior-generation engines

To date, the Pratt & Whitney GTF family engines have saved airlines more than 800 million gallons (more than three billion litres) of fuel and more than eight million metric tons of carbon emissions.

More than 1,300 GTF-powered aircraft have been delivered to 62 operators across three aircraft families, including the Airbus A320neo, Airbus A220 and Embraer E-Jets E2.

Worldwide, GTF engines have powered more than four million flights, carrying more than 500 million passengers to their destinations around the world.
