  • Commercial aircraft engine needs to satisfy International Civil Aviation Organization (ICAO) emission standards, the low emission combustor research and development is the key to make the engine development successful. TeLESSⅡ low emission combustor scheme was used to research the gas emissions property of two different pilot stage designs, namely, prefilming airblast atomizer and airblast simplex atomizer, with the same main stage air flow and fuel atomizing module. The results indicate that in low condition with different pilot stage designs,the emissions and combustion efficiency changes are different. In the high condition, according to fuel staging ratio, the emissions have different change trends, and the combustion efficiency change trend is the same. Those illustrate that the combination of pilot stage and main stage design change the combustion properties.
