Available in PDF, EPUB and Kindle. Book excerpt: 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).

Book excerpt: 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. A large number of potential blast simulator concepts were evaluated and their performance char acteristics were determined. Preliminary designs were made for those concepts which possessed the best over-all performance characteristics and estimates of their economic feasibility were established. Volume II consists of several appendices that are referenced in Vol. I, which give the details of the feasibility study analysis. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Nuclear blast effects on full-scale reentry vehicles (RV) and interceptor missiles required a sophisticated simulation technique. This technique employed a rocket sled with speeds of Mach 6, and the capability of separating and free-flying the structural model through simulated nuclear environments. The nonnuclear environments consisted of large free-air TNT detonations and dense, gas-filled, explosively driven, plywood shock tubes. All aspects of the 4-year experimental program are summarized in this volume of a five-volume report including what was simulated, the environment used, the sled design plus related techniques, and the instrumentation systems developed. The results of all experimental tests are included plus procedures, planning, and conducting future blast vulnerability studies, impacts, and full-scale proof tests. (Author).
