Structures, systems, and methods for energy distribution
Energy distribution structures provide architectural flexibility in various configurations, materials, and scalability, which enables a vast number of applications. An energy distribution structure or array thereof may include a three-dimensional outer component and a three-dimensional inner component within the outer component. The outer component absorbs and redirects initial energy from an applied energy event, and the inner component absorbs and redirects residual energy from the applied energy event. Such an applied energy event may be caused by a ballistic or non-ballistic impact, an instantaneous or prolonged impact such as atmospheric pressure or decompression, explosive overpressure (shockwave), low-velocity contact, and blunt force trauma. Energy distribution structures can increase the strength, resilience or survivability of such events, and reduce the injury or damage to target objects such as people, vehicles, structures, vessels and surfaces by shielding same from such events.
