What's the goal of LDI (lean direct injection)?

• Reduce emission while maintaining flame stability

• Inject fuel directly into flame zone to avoid flashback

• Fuel-lean combustion, reduce NOx emission

• Multi-swirler injection for uniform F/A mixing and low residence time

Fuel-staging features to simulate flight conditions (idle, cruise, SLTO)

Current results from testing have been very promising:

• Low equivalence ratio
• Ultra-low LBO

+ Future testing: Emission analysis on High Pressure Test Rig #1
