Engine upgrade option derived from GTF Advantage technology will nearly double time on wing

PARIS, June 16, 2025 /PRNewswire/ -- Pratt & Whitney, an聽RTX (NYSE: RTX) business, is introducing Hot Section Plus (HS+), an upgrade option for the PW1100G-JM engine that powers the Airbus A320neo aircraft family. Derived from the Pratt & Whitney GTF Advantage鈩⒙爀ngine, which will offer twice the time on wing of today's Pratt & Whitney GTF鈩⒙爀ngine, HS+ will provide 90 to 95% of the GTF Advantage's durability benefits.

"HS+ brings the durability improvements of the GTF Advantage hot section to today's GTF engine," said Nick Tomassetti, vice president, Sales & Marketing at Pratt & Whitney. "Customers operating the current GTF engine model will have the opportunity to nearly double time on wing."聽

HS+ includes only about 35 part numbers and will be incorporated during maintenance visits. The option will be available to customers for purchase, with installations starting in 2026. GTF engines with HS+ will be fully intermixable and interchangeable with both the current GTF and GTF Advantage engine models, simplifying operations with a combined fleet.

The GTF Advantage features the most state-of-the-art hot section in the single-aisle market. In the high-pressure turbine (HPT), the enhancements include an advanced airfoil design with improved coatings. The HPT and combustor also feature optimized cooling hole size, shape and location, with improved hole drilling techniques to reduce oxidation.

The GTF engine is the most efficient engine available for single-aisle aircraft, delivering up to 20% better fuel efficiency compared to the prior generation of engines, resulting in significant cost savings to operators.
