856A3498G02 is a precision-manufactured aerospace engine low-pressure compressor (LPC) rotor blade, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines. It is a core compression component in the LPC, accelerating and compressing the incoming air, providing pre-compressed air for the subsequent high-pressure compressor (HPC), which is critical for ensuring the engine's overall air compression efficiency, maintaining the air volume required for combustion, and supporting stable engine thrust output.

Made from high-strength, corrosion-resistant nickel-based superalloy, it withstands operating temperatures up to 770°C and continuous high centrifugal force and air scouring. Weighing 0.22kg with a precision-machined airfoil shape, it allows for fast installation and condition inspection during LPC MRO overhauls. FAA Part 25 certified, it is a key component for LPC operational efficiency.
