Full Core Restoration

What to Expect From A Full Core Restoration
Full Core Restoration Process for a CFM56 Engine
How It’s Done:
Initial Disassembly: The process begins with the complete disassembly of the engine’s core, including the high-pressure compressor (HPC), combustor, and high-pressure turbine (HPT). Each component is carefully separated for individual inspection.
Detailed Inspection: Every core component undergoes thorough inspection using advanced techniques like borescope inspections, non-destructive testing (NDT), and precision measurement tools. This helps identify any wear, cracks, corrosion, or other defects.
Component Repair and Replacement: Damaged or worn components are either repaired or replaced with OEM-certified parts. This can involve processes such as welding, machining, re-coating, and rebalancing of the core components.
Cleaning and Surface Treatment: All core parts are cleaned to remove debris, contaminants, and oxidation. Surface treatments, such as thermal barrier coatings or corrosion-resistant coatings, may be applied to protect the parts from future wear.
Reassembly: Once the components are restored, the engine is meticulously reassembled with precise alignment and torque specifications to ensure all parts fit together correctly and function as intended.
Testing and Validation: After reassembly, the engine undergoes comprehensive testing, including a performance run on a test cell. This step verifies that the engine meets all operational parameters, such as thrust output, fuel efficiency, and temperature limits.
Final Inspection: A final inspection ensures that all work has been completed to the highest standards, with documentation and certification provided for regulatory compliance.
