KHI has been conducting research and development of lean burn combustor technology under the project of Environmentally Compatible Engine for Small Aircraft led by New Energy and Industrial Technology Development Organization (NEDO) and Ministry of Economy, Trade and Industry (METI). Several concentric lean staged burners have been developed and evaluated through CFD analysis, spray tests, and single sector combustion tests. Combustor performance has been evaluated through multi sector tests with the combination of the burner and several combustor configurations. One of the burner and the combustor combinations showed about 63% NOx reduction potential from ICAO CAEP4 regulation. With this combustor specification, annular combustor test has been performed in JAXA AP6 test cell to raise the technical readiness level. This paper describes the annular test result together with the brief introduction on burner development activities through burner tests and multi sector tests.
