Abstract

A blast suppression panel comprises a hollow body (1) containing a plurality of symmetrical bodies arranged in layers (3,4,5) with successive layers displaced from each other by half the width of a symmetrical body. The base (1) of the panel contacts a structure to be protected. Blast shock passes through the face (2) of the panel and hits the first layer (3) of symmetrical bodies where the shock energy starts to be dissipated intrinsically and by bodily translation. The second layer (4) receives a shock imparted by the first layer, and by some of the original shock that escaped the first layer; this dissipatory process continues through succeeding layers, the suppression level achieved being determined by the number of layers.

DESCRIPTION
TITLE - BLAST SUPPRESSION PANEL Background & Problem. Blast from explosions can damage or destroy structures. There are patents that suppress blast but they introduce weight and size to suppress the blast by either obstructing it massively or reducing the heat of explosion with a mass of water or acoustically dampening the shock with a mass of various materials or a mixture of these, consequently they are either heavy or bulky or both.
Problem Solved. A blast suppression panel reduces the blast shock load on that part of a structure it masks by progressively harnessing the energy of the blast to work in opposition to itself and to translate its own direction. As the panel works solely by harnessing energy it relies on neither weight nor bulk.
Essential Features. A blast suppression panel is a hollow shape of material that contains a plurality of symmetrical bodies arranged in layers, each layer being displaced laterally from the previous layer by half the width of a symmetrical body. A blast suppression panel is placed in contact with the structure it is to protect.
Introduction to the Drawings. A blast suppression panel and the symmetrical bodies it contains can be any shape within the constraints of their essential features. However to aid description a panel is drawn as a hollow rectangular shape and the symmetrical bodies are drawn as spheres. There are two figures.
Fig.1 is the cross section of a panel in elevation.
Fig.2 is the plan view of a panel with its face on top.
How The Invention Performs A blast suppression panel is located with its base (1, Fig. 1) in contact with the structure it is to protect. In the event of an explosion the blast shock wave in air enters the panel through its face (2, Fig.1) and strikes the first layer of bodies (3, Fig.1). Intrinsic partial dissipation of shock energy occurs throughout this layer. Shock energy is also dissipated externally by translation of the bodies at the fringe of the layer into a direction different to that of the blast shock.
The second layer (4, Fig. 1) gains shock from the first layer and from that part of the original blast shock in air that passed through gaps in the first layer, and it, too, partially dissipates the shock both intrinsically and by external translation.
The third layer (5, Fig. 1) similarly dissipates the shock imparted by the second layer.
This process of shock partial dissipation continues through subsequent layers of symmetrical bodies, the number of layers determining the amount of shock reduction.
