PWA111100 is a precision aerospace component, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engine combustion systems.

It serves as an engine combustion chamber fuel spray bar, responsible for delivering and atomizing fuel into the combustion chamber, mixing it evenly with compressed air to support stable, efficient combustion. Stable fuel atomization ensures the engine maintains consistent thrust output, avoids local overheating that damages combustion components, and reduces exhaust emissions.

Made from high-temperature-resistant nickel-based superalloy, it can withstand operating temperatures up to 1600°C, and has a precision-drilled structure to control fuel flow and atomization effect. Weighing 0.76kg, it allows quick replacement during engine MRO, and is a key component for engine performance.
