Military pyrotechnic illuminating systems, whether launched by aircraft, artillery, mortar or rocket, contain a flare pellet which is ignited simultaneously with the ejection of a parachute system, deployed to slow the descent. Present flare pellets produce nominally constant intensity, and the illumination on the ground below the flare continually increases as the flare descends. Substantial improvements in performance and cost effectiveness would result from design optimization. However, field-testing of designs has proven costly, produced few results, and has not generally included all relevant parameters. The present paper describes a methodology for assessing flare performance and design, a mathematical model to implement it, and a computer program to handle the calculations we term this combination to MODEL.
