A Novel Blast-mitigation Concept for Light Tactical Vehicles

Abstract

A new concept solution for improving blast survivability of the light tactical military vehicles is proposed and critically assessed using computational engineering methods and tools. The solution is inspired by the principle of operation of the rocket-engine nozzles, in general and the so called pulse-detonation rocket-engines, in particular. The proposed concept utilizes side vent channels attached to the V-shaped vehicle underbody whose geometry is optimized with respect to the attainment of the maximum downward thrust on the vehicle. In the course of the channel design optimization, analytical and computational analyses of supersonic flow (analogous to the one often used in the case of the pulse detonation engine) are employed. The preliminary results obtained reveal the beneficial effects of the side channels in reducing the blast momentum, although the extent of these effects is relatively small (2-4%).
