EFFECTS OF CASE COATING ON LOADING AND BURNING CHARACTERISTICS OF EXPERIMENTAL ILLUMINANTS FOR XM-145 AND XM-146 GROUND SIGNALS
Abstract
Static performance tests were conducted n flare compositions producing red and yellow light, using convolute-wound filter paper cases with the XM-146 yellow light systems and convolutewound kraft paper with the red light XM-145 systems. These cases were 3.83 in. long and had an inner diam of 1.19 in. Results were compared on the basis of the decisive parameters of ignition characteristics, candlepower, burning time, and ease of loading. Polywax (67/33), polywax (80/20), Thiokol, Coast Pro-Seal, and graphite were investigated as case coatings. Candlepower was found to depend on the type of case coating used and the temperature range to which the coated cases were subjected. Burning time was found to be generally independent of factors which affected candlepower. No case coating investigated met all requirements. Slag formation and/or chimney formation, possibly ca se by case material or case coating or both, could have been responsible for occasional severe reductions in candlepower. (Author)
