Calculations of Thrust Generation by the Driver System of a Large Blast Simulator

Abstract

A computational study was performed to determine the peak thrust which would be generated by cylindrical shock tube drivers of various lengths. Thrust histories were generated for two different flow conditions, one in which the shock tube was operated normally and the other in which a driver length adjusting device (hydroplug) failed. Once the magnitude and behavior of the thrust histories are understood, steps can be taken to design supports for the driver tubes which will withstand the cyclic loading associated with normal operation as well as the reverse loading associated with the component failure.
