Pratt & Whitney has rolled out a Hot Section Plus (HS+) upgrade option for the PW1000G-JM aboard the Airbus A320neo family, offering the potential to nearly double the engine’s time on wing. HS+ incorporates technology derived from the GTF Advantage engine, offering 90% to 95% of its durability benefits.
“HS+ brings the durability improvements of the GTF Advantage hot section to today’s GTF engine,” said Nick Tomassetti, v-p of sales and marketing at Pratt & Whitney.
The upgrade involves only 35 part numbers and can be installed during maintenance visits beginning in 2026. GTF engines with HS+ will be interchangeable with both GTF and GTF Advantage models, which Pratt & Whitney noted would simplify operations of a combined fleet.
Certified on the Airbus A320neo series in February, and with first production deliveries anticipated later this year, the GTF Advantage brings an advanced airfoil design with improved coatings in the high-pressure turbine (HPT). The HPT and combustor also have optimized cooling hole size, shape, and location with improved hole drilling techniques to reduce oxidation.
