Temperature measurements of shocked energetic materials by time-resolved infrared radiometry
Temperatures of solid explosive and propellants were measured in 102 mm projectile-impact experiments using two-band, time-resolved infrared radiometry. Two different arrangements were used. In one, temperature measurements were made on the downstream face of bare charges; in the other, the material was confined by a shock-impedance matched, infrared-transmitting window. The bare-charge results yield temperature histories consistent with formation and decay of hot spots, and different particle sizes resulted in large differences in behavior, which were interpreted in terms of hot spot theory. Window confinement provided reaction histories and rate data which constitute a new measurement of progress of reaction in shock initiation.
