PWA211416 is a precision-manufactured aerospace engine high-pressure turbine (HPT) rotor blade, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines. It is a core energy conversion component in the HPT, converting the thermal energy of high-temperature, high-pressure exhaust gas into rotational mechanical energy, which is critical for driving the HPC and engine accessories, and ensuring the engine's overall power output.

Made from high-strength, heat-resistant and oxidation-resistant single-crystal nickel-based superalloy, it withstands operating temperatures up to 1500°C and continuous impact from high-speed gas flow and high rotational stress. Weighing 0.12kg with a precision airfoil cooling structure, it allows for fast installation and condition inspection during HPT MRO overhauls. FAA Part 25 certified, it is a key component for HPT operational efficiency.
