Gaseous (NOx, CO) and non-volatile particulate matter (nvPM) emissions from a small-core high-pressure Axially Controlled Stoichiometry (ACS) combustor are reported. NOx and CO emissions characteristics are similar to a previous version of ACS combustor. Emissions of nvPM at low-power (fuel-rich front end) was found to procude significantly higher nvPM emissions compared to a high-power configuration (fuel-lean front end). NOx emissions for the ACS combustor were 82-89% below the ICAO CAEP/6 standard for aggressive NASA N+3 high-pressure cycles based on NOx correlations developed from experimental measurements.
