The Pratt & Whitney PW1100G engine, part of the P&W GTF series used on the A320neo, has been updated to the GTF Advantage (GTF-A). Announced in December 2021, this new variant promises enhanced fuel efficiency, durability, and improved thrust at high-altitude airports.
Tom Pelland, GTF chief engineer at Pratt & Whitney, claims that the GTF-A will provide "8% greater thrust at hot and high airports, and 4% better thrust at sea level." This update builds upon previous sustainable aviation fuel (SAF) testing with aims for 100% SAF compatibility.
Pratt & Whitney has achieved these advancements by optimizing airflow control between turbine and seals, lowering compressor temperatures, and utilizing durable coatings. Risk Deurloo, President of Commercial Engines for Pratt & Whitney, remarked: “GTF engines already offer the lowest fuel consumption and CO2 emissions for single-aisle aircraft. The GTF Advantage engine extends that lead.”
