Height Along an RDX Flame

Temp and relative intensities of the combustion products detected as a function of height along an RDX flame are shown in Fig 8 (Ref 67d). Intense radiation from the OH radical is observed immediately next to the combustion surface of the RDX sample. The intensity of the radiation attains its max value at a distance of 0.1mm and varies slowly with further increase in height along the flame. Luminescence of the radicals C2, CN, and CH appears at a distance of 0.1—0.2mm from the combustion surface and increases markedly as the zone of max temp in the flame is approached...
