Abstract : Spectra have been obtained in the visible spectral region from the Navy Mk 45 and the Air Force LUU-2B/B aircraft parachute flares. Marked differences are noted particularly in the region of the sodium D resonance line radiation and in the red region of the spectrum. The broadening of the sodium resonance lines is considerably less in the LUU-2B/B than in the Mk 45. There is also considerably less radiation in the red spectral region from the LUU-2B/B. Color data and candlepower are presented for both flares. An explanation of the differences in the spectra is given in terms of the radiative transfer model. (Author)
