On Command Pyrotechnic Light Emission Through Controlled Electromagnetic Irradiations
Abstract
Development of next generation pyrotechnic emitters requires a paradigm shift away from the “emission control via formulation” use of such hazardous reactants toward development of universal formulations with on-command, selectable emission characteristics. Development of high-brilliance pyrotechnic emitters has also traditionally required addition of toxicological and environmentally harmful additives in order to achieve necessary color purity and brilliance. The objective of the proposed effort is to develop on-command microwave-selectable color and intensity emissions within a single pyrotechnic formulation by exploiting electromagnetic-flame interactions. The development of this technology will enable a tunable, multi-color, multi-purpose pyrotechnic, where environmental impact could be achieved via (1) reductions in size/weight of ordnance to produce desired photoemission impulse, (2) reduced inventories due to multi-purpose use, and (3) the ability to produce spectral photoemission from environmentally friendly formulations that, without microwave irradiation, are incapable of satisfying photoemission color purity/intensity requirements.
