Pyrotechnic Flare Spectroscopy III
Abstract
Illuminating flares are typically made from a mixture of magnesium, sodium nitrate, and a binder. Light is emitted from these flares at a luminous efficiency of about 50,000 candle-seconds/gram. To satisfy the continuing need to generate light more efficiently, the specific objective of this work is directed toward determining the mechanisms by which light is emitted from illuminating flames, the new knowledge providing the basis for future improvements. The approach being taken is to study emission spectra of illuminating flames tested at various pressures and with different formulas. The aim of these studies is to relate the experimental observations to some set of parameters which characterizes the state of the flame. Theoretical models and prediction equations are being developed which predict the flare output based on knowledge of the flare formula, flare size, and ambient pressure.
