New design concept and combustion test results of a high intensity aero-engine combustor are described. A new combustor nemed "Jet-Swirl Combustor" has been developed to attain a combustion loading 50% higher than that of conventional combustors. The concept of the "Jet-Swirl Combustor" is that generates a ring of swirling vortexes to accelerate the mixture of fuel with air, and promote rapid combustion of the mixture, thus to enhance the combustion rate in the primary combustion zone. A numerical analysis of a three dimensional flow in the combustor was carried out to determine the configuration of a combustor. A protoype combustor has been tested to examine the combustion efficiency under the high combustion loading conditions, and to measure the concentrations of the combustion products in the combustor. The test results showed the extremely high combustion efficiencies even under the high combustion loading conditions. It is concluded therefore that the improvement of the combustion loading is possible by the combustion enhancement due to the strong jet-swirl motion in the combustor.
