856A3320G04 is a precision-machined aerospace high-pressure compressor (HPC) stator vane, engineered to AS9100D standards and FAA/EASA regulations, optimized for CFM56-5B/7 and IAE V2500 turbofan engines. It guides and straightens airflow exiting each compressor rotor stage, minimizing turbulence, boosting compression efficiency, and maintaining stable pressure ratios across all engine thrust settings—critical for reducing fuel burn and enhancing overall engine performance.

Crafted from heat-resistant nickel-based alloy with a wear-resistant coating, it operates reliably at temperatures up to 600°C and withstands high-frequency vibration. Weighing 0.11kg with an integrated dovetail mounting design, it enables rapid replacement during HPC section MRO overhauls. FAA Part 25 compliant, it is a key component for sustaining compressor stability and operational durability.
