Book Description
The blast parameters for the 6-foot diameter by 200-foot long, explosively driven shock tube are presented in this report. The purpose, main characteristics, and blast simulation capabilities of this PETN Primacord, explosively driven facility are included. Experimental data are presented for air and Sulfurhexaflouride (SF6) test gases with initial pressures between 0.5 to 12.1 psia (ambient). Experimental data are presented and include shock wave time of amval at various test stations, flow duration, static or side-on overpressure, and stagnation or head-on overpressure. The blast parameters calculated from the above measured parameters and presented in this report include shock wave velocity, shock strength, shock Mach number, flow Mach Number, reflected pressure, dynamic pressure, particle velocity, density, and temperature. Graphical data for the above parameters are included. Algorithms and least squares fit equations are also included.

Book Description
This report represents the final stage of distributed breach development for the conical shock tube. An initial design of the distributed breach has been used to find the effect of prestressing before firing on the stress state after firing. Finite element method has been used to evaluate in-plane and hoop stresses before and after firing. A coarse finite element model is used to find points of high stresses before a finer mesh thereat is adopted. Results confirm the existence of a prestress three dimensional continuum which creates a very high resistance to firing loads. In fact, stresses have literally been improved after firing due to prestressing effect. The results of the initial design led to modifications which an further improve the stress distribution in the breach. The improved design with its working drawing is included in the redesign section of this report. The next stage is the manufacturing and testing of the improved design. This will be included in this final report of the project. Test results indicate a marked improvement over the old tube. No failure has occurred and the efficiency of simulating real blasts is about 90% which is much higher than the old tube. (Author).
