DETONATION-GENERATED IONIZATION WAVES AT REDUCED PRESSURES

摘要

Investigations were conducted into the phenomena accompanying detonation of RDX charges in constraining tubes at reduced air pressure. Electrostatic probe and photomultiplier techniques were used to measure the conduction, luminosity, and velocity of the ionization wave which was expelled from the free surface of the explosive. Velocity data were also obtained for the detonation products. Color and infrared framing camera photographs of the ionization wave phenomena were obtained at different initial air pressures. The experimental results were compared with results reported of shock wave phenomena in shock tubes.
