Aviation Week reports, “Pratt & Whitney is projecting high-single-digit commercial aftermarket growth in 2026, bolstered by strength in several areas. Upticks in volume within Pratt’s biggest large-engine programs, the PW1000G geared turbofan (GTF) and the IAE V2500, will drive the engine-maker’s MRO business this year.”

Airbus Places Cold-Weather Takeoff Restrictions on A320neos Powered by PW1100G Engines
Aerotime reports, “Airbus has introduced new cold-weather takeoff restrictions for A320neo-family aircraft equipped with Pratt & Whitney geared turbofan engines, following operational issues reported in freezing fog conditions. The new restriction applies to aircraft powered by PW1100G engines and limits takeoffs during freezing fog when the visibility drops below 150 meters. Airbus said it has updated the ground-engine operating procedure for icing conditions, a change intended to reduce the risk of performance degradation during the most severe winter weather.”

Aviation Week Article: Pratt & Whitney Unveils Details Of Hydrogen-Steam Hybrid Engine Cycle
Guy Norris at Aviation Week reports, “Hydrogen fuel may offer attractive pathways toward the goal of zero carbon emissions, but turning that vision into a practical propulsion system is another matter. Now Pratt & Whitney thinks it may have taken the first steps along that path with the Hydrogen Steam-Injected, Intercooled Turbine Engine (HySIITE) concept—a novel hybrid engine configuration that combines the advantages of the fuel’s cryogenic properties with the thermodynamic benefits of steam injection. Pratt & Whitney has unveiled details of the concept, which has been studied under a two-year $3.8 million U.S. Energy Department Advanced Research Projects Agency–Energy (ARPA-E) effort. While Pratt acknowledges the cycle is complex and requires more study, it is encouraged by the results, which show potential for as much as 35% lower energy use compared with current state-of-the-art engines.”
