CFM Introduces Upgraded HPT Blade for CFM56 Engines

Issue: 10-2023

CFM announced that it is offering an upgraded High-Pressure Turbine (HPT) blade designed to enhance the durability of its CFM56-5B and CFM56-7B engines. The new blade design leverages millions of hours of engine field data. Updates include increased wall thickness, optimised dovetail loading, and tightened manufacturing tolerances. The blade maintains the fuel burn benefit achieved with CFM56 Tech Insertion blade configurations launched in 2007.

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 part per week and 250,000 parts per year.
