VISIBLE RADIATION CHARACTERISTICS OF NYLON, LEXAN AND KEL-F IN AIR, NITROGEN AND CARBON DIOXIDE,

Abstract

Spherical projectiles 1/4 inch in diameter were launched into each of three gases: air, nitrogen and carbon dioxide at a pressure of 100 mm of mercury. The velocity span for the nylon, lexan and Kel-F spheres was between 13,000 and 16,000 feet per second. The radiation surrounding each sphere was detected by a multiplierphototube system sensitive to the visible spectrum from approximately 3,500 to 6,500 angstroms. The magnitude of the radiation emitted from the shock region was plotted as a function of velocity for each combination of plastic material and gas composition. The radiation traces of the wake region are also compared. (Author)
