Concept Validation and Optimization for a Vent-Based Mine-Blast Mitigation System
Abstract
In this project, a new solution for improving blast-survivability of light tactical military vehicles to detonation of a shallow-buried mine underneath them has been introduced and analyzed computationally. The solution involves the use of side-vent-channels attached to the Vshaped vehicle underbody, and tries to exploit detonation-products ultrasonic-expansion and ejected-soil venting phenomena to generate a downward thrust on the targeted vehicle. In order to accurately account for the interaction of detonation products, ejected soil and blast waves with the target structure, a novel combined Eulerian/Lagrangian finite-element/discrete-particle computational method has been developed and employed. To assess the full blast-mitigation potential of the new concept, the finite-element-based analysis has been combined with an advanced multi-objective design-optimization procedure. The results obtained show that the proposed concept has a relatively limited (but respectable) ability to reduce the detonation-induced total momentum transferred to, and the acceleration acquired by, the target vehicle.
