HU55322-2 is a precision-manufactured aerospace engine combustion chamber fuel nozzle component, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines. It is a core fuel distribution component in the combustion chamber, atomizing and evenly injecting aviation fuel into the combustion chamber to mix with compressed air, which is critical for ensuring sufficient, stable and complete fuel combustion, controlling the combustion temperature, and reducing the emission of harmful exhaust gases.

Made from high-temperature-resistant, corrosion-resistant nickel-based superalloy, it withstands operating temperatures up to 1580°C and continuous thermal impact. Weighing 0.22kg with a precision-machined atomization structure, it allows for fast cleaning and atomization effect detection during combustion chamber MRO overhauls. FAA Part 25 certified, it is a key component for combustion chamber operational efficiency.
