Abstract:
1. A blast-resistant structure for the hull of a land vehicle having a vehicle centerline, the structure comprising: two vertex structures, each vertex structure having a planar inner wall joined to a planar outer wall along a bottom edge thereof to form an apex line along a longitudinal length of the vehicle, the outer wall extending upwardly and outwardly from the apex and the inner wall extending upwardly and inwardly from the apex; and a downwardly concave structure connecting and being supported by the inner walls, the concave structure having a substantially flat horizontal upper portion and being symmetric about a structure centerline that is coplanar with the vehicle centerline; wherein the vertex structures and the concave structure are collectively configured so that when the blast-resistant structure is subjected to an explosion between the two vertex structures, a shockwave resulting from the explosion will impact the inner wall of each vertex structure before impacting the substantially flat horizontal upper portion of the concave structure, causing horizontal deformation of the inner walls of the vertex structures producing a downward force on the substantially flat horizontal upper portion of the concave structure.
