Abstract : This research encompasses two promising techniques for extending aircraft operational range. They are radiative and catalytic augmentation techniques to enhance combustion initiation and reaction kinetics which restrict combustor operation via limits on flammability, flame propagation, ignition and stability. Both techniques have demonstrated the capability to enhance combustion processes and to broaden normally encountered stability limits. The radiative technique under laboratory static conditions has successfully ignited fuel-air mixtures, and has enhanced combustion processes, utilizing pulsed and continous VUV light sources. Similarly, the catalytic technique has provided efficient combustion under normally difficult fuel lean, low temperature, conditions. A complementary effort involves the development of analytical capability required for modeling the radiative and catalytic techniques. Radiative ignition and combustion enhancement tests have been performed on gaseous mixtures under various static conditions. Successful radiative ignitions were obtained with pulsed and continuous vuv/uv light sources. The ignition with the continuous light source was reported for the first time. Combustion enhancement experiments were conducted with continuous velocities and larger extinction times and extinction distances were also reported.
