PWA211344 is a precision-manufactured aerospace engine high-pressure turbine (HPT) stator vane, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines. It is a core gas-guiding component in the HPT, guiding the high-temperature, high-pressure exhaust gas to flow to the HPT rotor blades in the optimal direction, which is critical for maximizing the energy conversion efficiency of the HPT, ensuring the engine can output stable rotational power to drive the HPC and other accessories.

Made from high-strength, heat-resistant and oxidation-resistant nickel-based superalloy, it withstands operating temperatures up to 1490°C and continuous scouring from high-speed exhaust gas. Weighing 0.09kg with an integrated 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.
