Abstract:

A theoretical analysis is made of the mechanical effect of a detonation occurring in a closed bomb during routine propellant testing in the pressure range for which convective burning is expected to develop. A hitherto unreported phenomenon was found, consisting of an amplification of the peak reflected detonation impulse by products of combustion and leading to a maximum impulse as a result of a detonation occurring during the first third of burning. Graphical results of the analysis are presented for a standard combustion bomb using an experimental propellant. Limitations imposed by instrumentation, especially pressure gauges, appear to be more severe than these imposed by mechanical construction over the range of experimental parameters of interest.
