Abstract : The object of this research program is to determine the most feasible means of obtaining a nuclear blast simulator which will reproduce the transient flow field associated with the 500 psig. overpressure range of large nuclear weapon detonations. The blast simulator is of the general purpose type and is characterized by a traveling shock wave followed by a flowing gas. The test section is of the order of 25 x 50 feet in section and contains, in addition to the gas flow region, a soil container or region in which air induced stress waves can be generated. Two concepts were considered the most feasible. One is the standard shock tube concept which consists of a long tube, closed at one end, in which explosives are distributed over a large region and detonated. The other is the space variable energy input shock tube concept which consists of a long tube, open at both ends, in which explosives are distributed in a non-uniform manner. The resulting detonation yields longitudinal pressure gradients which are similar to the wave forms of interest. Both of these concepts simulate the overpressure and dynamic pressure variation in the test section satisfactorily. Cost estimates for these two concepts were made for a variety of facility sizes and blast wave parameters. (Author)
