Innovative Low-NOx Fuel Injector for Aircraft Engine Combustors

DESCRIPTION

This innovative piloted airblast lean-direct fuel injector features a bifurcated flow pattern designed to significantly reduce emissions in aircraft engines. Achievements include a remarkable 60-65% reduction in NOx emissions compared to 1996 ICAO landing-takeoff cycle standards and demonstrated ignition reliability at low equivalence ratios. With approximately $1.5M funding from major engine manufacturers and backing from NASA's Advanced Subsonic Technology and Ultra-Efficient Engine Technology programs, this technology shows promising potential for commercial applications and government interest.
