856A2728G02 is a precision-manufactured aerospace engine high-pressure turbine (HPT) blade, compliant with AS9100D quality standards and FAA/EASA regulations, optimized for CFM56 and IAE V2500 turbofan engines. It converts the thermal energy of high-temperature, high-pressure combustion gases into rotational mechanical energy, driving the HPC and engine accessories, which is the core power conversion component supporting engine thrust output across all flight phases.

Made from a heat-resistant nickel-based superalloy with a thermal barrier coating, it withstands operating temperatures up to 1,650°C and extreme centrifugal forces. Weighing 0.22kg with a precision-machined dovetail root, it enables accurate mounting and replacement during hot-section MRO overhauls. FAA Part 25 certified, it is a core component for engine power conversion and operational efficiency.
