A Dynamic Crater Ejecta Model
Abstract
A dynamic model for the high explosive and nuclear crater ejecta environments is presented, together with selected results for a 1 MT surface burst on hard rock. The model provides both the ground deposition and airborne ejecta cloud environments. The effects of explosive type, yield and geology are taken into account in the model. The deposition results are obtained in the form of the cumulative mass and number of fragments impacting the ground plane per unit area, the ejecta depth, the fragment size class (minimum an maximum fragment diameters) and the minimum and maximum values for the impact time, velocity, angle, momentum and kinetic energy as functions of range from the burst point. The ejecta cloud environment is given in the form of mass and number densities as functions of spatial position and time.
