A Combined Finite-Element/Discrete-Particle Analysis of a Side-Vent-Channel-Based Concept for Improved Blast-Survivability of Light Tactical Vehicles
Abstract
The recently proposed concept solution for improving blast-survivability of the light tactical military vehicles is critically assessed using combined finite-element/discrete-particle computational methods and tools. The proposed concept involves the use of side-vent-channels attached to the V-shaped vehicle underbody. Since the solution does not connect the bottom and the roof or pass through the cabin of a light tactical vehicle, this solution is not expected to: (a) reduce the available cabin space; (b) interfere with the vehicle occupants ability to scout the surroundings; and (c) compromise the vehicle s off-road structural durability/reliability. Furthermore, the concept solution attempts to exploit ideas and principles of operation of the so-called pulse detonation rocket engines in order to create a downward thrust on the targeted vehicle. To maximize the downward thrust effects and minimize the extent of vehicle upward movement, standard engineering-optimization methods and tools are employed for the design of sidevent- channels. The results obtained confirmed the beneficial effects of the side-vent-channels in reducing the blast momentum, although the extent of these effects is relatively small (3 4%).
