In the fall of 1968 the conical shock tube, DASACON, at the Naval Weapons Laboratory in Dahlgren, Virginia was instrumented with a system designed to make air flow speed measurements. The measurements were made at the third or largest test station in DASACON. During the series of tests a variety of driver charge weights, varying from 60 to 700 lbs of TNT, was used. This essentially covers DASACONs range of capabilities. The principal results of the test program were the following 1 In those regions of the shock tube where flow is not disturbed by mounting structures the measured air speed versus time profiles agree well with profiles based on a method of characteristics analysis. The measured peak speeds are well predicted by means of existing peak pressure data. unsteady for extended periods after shock arrival. The duration of this turbulent flow increased with charge size.
