VEHICULAR BASED MINE BLAST ENERGY MITIGATION STRUCTURE
First Claim
1. A blast energy mitigation system for mitigating effects of an explosive blast on a vehicle having a chassis, the blast energy mitigation system comprising:
- an energy absorbing structure attached to an underside of the vehicle chassis and adding rigidity thereto, the energy absorbing structure comprising structural members fastened together to form a truss-like structure, the truss-like structure comprising an upper and a lower horizontal flange portion connected by a vertical web portion to form an I-beam shape; and
a V-shaped hull connected to and covering the underside of the energy absorbing structure.

Abstract
A blast energy mitigation structure may employ a V-shaped hull to decrease the pressure wave imparted to a vehicle during a blast event, and/or an energy absorbing structure to absorb a portion of the blast force, thereby minimizing the forces and accelerations experienced by passengers in the vehicle and consequently reducing their injuries and increasing their survivability during a blast event. An exemplary blast energy mitigation structure may have a V-shaped hull and an energy absorbing structure incorporated into the chassis of a vehicle such as a Tactical Wheeled Vehicle, the energy absorbing structure comprising a truss-like structure including I-beams.
