Pratt & Whitney has unveiled a new single-aisle aircraft engine.

Dubbed “the world’s most fuel-efficient and sustainable engine”, the ‘GTF Advantage’ decreases fuel consumption and CO2 emissions by 17 per cent compared to prior-generation engines, the company said.

The GTF Advantage will be compatible with 100 per cent sustainable aviation fuel when it enters service in January 2024.

“GTF Engines met or exceeded fuel, emissions and noise commitments from day one and have since achieved a strong record of dependability and low operating cost,” said Pratt & Whitney’s president of commercial engines Carrol Lane.

“GTF Advantage provides even more value to our customers, both in revenue potential and environmental impact, with lower fuel burn and new route opportunities.”

The new configuration also delivers higher thrust, the company said, both at sea level and for “hot and high” airports. With up to 34,000 pound of takeopff thrust per engine, the GTF Advantage will be the most powerful engine for the A320neo family.

“We always said our general fan architecture has a long runway for growth and future development, and the GTF Advantage demonstrates this,” added Pratt & Whitney’s senior vice president of GTF Engines Tom Pelland.

“Our gear system, and the overall engine architecture it enables, are foundational to unlock the benefits of advanced aerodynamics, materials and systems. We are committed to continuing to invest in these technologies for the next generation of commercial aircraft.”

For “a seamless introduction for operators”, the new configuration will be interchangeable with already delivered engines and will become the new production standard for A320neo family aircraft.
