Frangible components and their use in a system for energy absorption

摘要

Embodiments of the present invention provide a core of individual components having properties such that a system assembled from the components absorbs the kinetic energy of a moving vehicle. The components may be interlocking components. The components may be manufactured of ceramic or polymeric composite or other materials that are strong enough to absorb the vehicle's energy and help stop the vehicle safely by the system's ability to crush or deform upon impact, and not so strong that it causes the vehicle to crumple against the barrier. In one particular embodiment, the components may be modified packing elements that are traditionally used in gas to liquid columns.

主权项

1. An energy absorbing system for arresting a vehicle, comprising:
a crushable barrier structure formed from a plurality of individual brittle components, the plurality of individual brittle components packed at random and providing an isotropic energy absorbing system, wherein the plurality of individual brittle components are interlocking components interlocked to one another and shaped as a partial arc, have arm protrusions that secure with respect to another component, or both, wherein the components are formed of a material that pulverizes under the weight of wheels of an overrun aircraft; and wherein airborne debris during vehicle engagement is minimized due to interlocking, pulverization, or both.
