Abstract:

High-speed framing camera photographs were used to observe the stress waves generated in thick-walled Lucite tubes 3 inches OD, 38 inch ID and in a Lucite block termination, by shock and combustion processes within the axial core. The stress waves were observed using an argon bomb for backlighting and crossed polarizers. Results obtained for axial cores of air, inert powder, granular RDX, and C4 were used in interpreting the results for a core of 6040 granular mixture of potassium perchlorate and aluminum. For the latter, it was concluded that although the elastic wave velocities in the Lucite exceed the combustion front velocity 900 ms, there is no precursor action, via the Lucite, on the 6040 mix. Intensification of luminosity in the core at the surface of the terminating block, prior to arrival of the front, was noted for air and 6040 cores. Author
