Abstract : Two novel concepts for extending aircraft operational range have been researched under this contract. They are radiative and catalytic augmentation techniques. The objective is to investigate the feasibility of the techniques to enhance combustion initiation and reaction kinetics which restrict combustion operation via limits on flammability, flame propagation, ignition and stability. Both techniques have demonstrated the potential to enhance combustion processes and to broaden normally encountered stability limits. The radiative technique under static conditions has successfully ignited fuel-air mixtures, and has enhanced combustion processes, utilizing pulsed and continuous VUV light sources. Similarly, the catalytic technique has provided efficient combustion under normally difficult fuel lean, low temperature, conditions. A complementary effort has focused on the development of analytical capabilities required for modeling the radiative and catalytic techniques. (Author)
