An overview is given of hypothesis-based combustion technology and product design and development practiced since the early 1970s applied successfully for 36 combustion systems including description of author’s six most favorite advanced combustion schematics. The challenges of developing the three technologies and products, low emission combustors (LECs), dual-annular combustors (DACs) and TAPS at GE Aviation and CFM, and the lessons learned to further continue making continuing progress have been summarized. While the landing takeoff NOx of the third-generation single venturi lean direct injection demonstrated in an idealized multi-injector test rig shows potentials for achieving 50% reduction compared to current lowest NOx GEnx TAPS combustor, its future activities should be focused on reducing low-power CO and HC emissions in addition to commonly encountered operability challenges associated with lean-dome combustors.
