Effects of Pipe Wall Mass Distribution in Line-of-Sight Nuclear Tests

摘要

The results of a continuing investigation into the possibility that the introduction of asymmetries into the horizontal line-of-sight pipe on a nuclear event may be able to reduce the flow of energetic materials down this pipe is presented here. In an attempt to model the three-dimensional asymmetric configurations, two-dimensional planar calculations were made in which the spiral wrap was approximated by alternating pieces of iron along the top and bottom of the pipe (channel). For the cases studied, it appears that increasing the amount of iron around the pipe reduces the energy of the jet and that this iron should be placed symmetrically about the pipe. However, the results indicated some deflection of the jet off axis in the spiral approximated.
