Series of experimental researches have been conducted to develop a combustor for a small class aircraft engine (with pressure ratio about 20). Target combustor is required to reduce NOx emissions below 50% of the ICAO CAEP4 standard, with high combustion efficiency over a wide range of operating conditions. Rich-Lean combustion approach was applied for the design concept, and basic configurations such as air mass flow distribution were investigated through tubular and rectangular single-sector combustor tests under atmospheric conditions. Based on the obtained results, 3/16 multi-sector combustors were designed, tested and investigated through combustion tests under high pressure and temperature conditions. Tuned combustor shown good combustor characteristics such as low blowout and exit temperature distribution, and also NOx emissions were reduced below 42% of the ICAO CAEP4 standard. Design process of the combustor and obtained results utilized for the tuning of the combustor are described in this report.
