A Compact Solid State Infrared Flare

In this Phase I SBIR proposal Physical Sciences Inc (PSI) outlines the development a solid-state emitter package to replace the propellant based candle of the M278 Infrared flare. Propellant combustion in the current candle technology is unsteady, resulting in variations in the illumination intensity and also produces a visible signature that limits it usefulness in covert activities. The proposed flare technology will use solid-state components (Light Emitting Diodes or laser diodes) to generate Infrared illumination that will overcome these limitations of candle illumination. In the Phase I, PSI will develop a prototype design for the solid-state emitter package that is compatible with the current dimensions and weight of the M278 candle. The design process will include: 1) Emitter component characterization and selection, 2) optical system design to combine the output of multiple emitters to achieve the specified output radiance intensity (250 W/sr), 3) Evaluation and selection of a power system to drive the emitters and control circuitry and 4) Preliminary mechanical design that integrates these components. In Phase II the prototype will be built and tested, both in the laboratory and in the field.
