PWA211492 is a precision-manufactured aerospace engine high-pressure turbine (HPT) blade, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines. It is a core power conversion component in the HPT, converting the thermal energy of high-temperature, high-pressure exhaust gas into rotational mechanical energy, which drives the HPC and engine fan to operate, critical for ensuring the engine's power output efficiency.

Made from high-performance single-crystal nickel-based superalloy, it withstands operating temperatures up to 1520°C and continuous scouring from high-speed exhaust gas. Weighing 0.42kg with a precision-machined airfoil with cooling channels, it allows for fast replacement and flaw detection during HPT MRO overhauls. FAA Part 25 certified, it is a key component for engine operational efficiency.
