Summary | Seabed effectors are considered as a tool for use in adversarial threat neutralization adjacent to and along the ocean floor. Implosion, the rapid collapse of a volume, in this case by extreme hydrostatic pressure, is proposed as means of accomplishing this function as it can potentially generate a greater shock loading than a conventional underwater explosion event at depth. However what is yet to be determined is the actual damage potential, process effectiveness and possible hazard to the delivery platform. The implosion event, seabed effector and representative target models are investigated through fully coupled fluid structure interaction hydrocode simulations. Design and environmental parameters are varied to examine the sensitivity of the structural model response and efficacy of the implosive loading in creating material or functional failure of the target. Focusing effects related to the implosion are also investigated in order to discover possible enhancement of implosive source yield. Characterizing the damage potential of implosion at depth will enable weapon designers and mission planners to develop and implement appropriately outfitted seabed effectors for this type of undersea warfare. |
