A Multidriver Shock Tube Model of a Large Blast Simulator
Abstract
The construction of the BRL Multidriver Shock Tube (MD-ST) Model is documented. The facility is a 1:22 model of the Large Blast Simulator at the Centre d'Etude de Gramat, France, except for a lengthened driven tube to permit observation of the full waveform development without interference from the open-end, reflected rarefaction wave (since the Rarefaction Wave Eliminator was not modeled). It is designed with a good safety factor to withstand driver pressures to 24,000 kPa (3,500 psi). Initial tests to greater than 22,100 kPa (3,200 psi) have been performed, and results are compared to other available data. Additionally, the double diaphragm technique, described in this report, was used to attain the highest shock pressures. Keywords: Blast simulators, Blast waves, Shock tubes.
