SAFRAN: CFM INTRODUCES UPGRADED HPT BLADE FOR CFM56 ENGINES

The new blade design leverages millions of hours of engine field data. Updates include increased wall thickness, optimized dovetail loading, and tightened manufacturing tolerances. The blade maintains the fuel burn benefit achieved with CFM56 Tech Insertion blade configurations launched in 2007.

“These upgraded CFM56-5B/-7B HPT blades are designed to keep our customers flying with OEM parts they know and trust,” said Jacey Welsh, CFM Executive Vice President – CFM56 at GE Aerospace. “Many of our customers are transitioning their narrowbody fleets and the new CFM56 HPT blade can help them to extend time on-wing to optimize cost of ownership and enhance the residual value of their engines. We are also providing attractive upgrade options to customers operating older CFM56 configurations.”

The new HPT blades are being produced in Greenville, South Carolina. This state-of-the-art GE Aerospace facility, with 250 employees, has manufactured HPT blades for a diverse portfolio of commercial and military engines for more than a decade. On average, the site ships 1,000 parts per day, 5,000 parts per week and 250,000 parts per year.

CFM engines are designed, tested, and certified at the engine operating system level, ensuring optimized system and product performance. The CFM56-5B and -7B have a world-class dispatch reliability rate of 99.98%.
