Abstract:

The application of the Cordin streak camera to the study of the relative position of the luminous zone, the ionization zone, and the compression wave activity during the initiation process in solid propellants was investigated. A transparent glass wafer was placed in the charge for the purpose of forming an image on the camera entrance slit. Two configurations were used 1 the wafer passed across the entire width of the strand or grain where the luminosity along the wafer surfaces through the wafer 2 the wafer extended into the axis of the charge. The second method was better as the front luminosity recorded was from the detonation zone the radial wafer indicated strong shock luminosity ahead of detonation. Development of the pressure- resistance element system for continuous determination of the compression wave position was continued.
