Abstract
A block of compressible material, such as cellular concrete, provides compressive failure characteristics suitable for arresting travel of an aircraft (or other vehicle) overrunning a runway (or other surface). Relatively thin frangible material positioned above the block provides a stronger, more damage resistant surface, while still readily fracturing in an arresting incident. Intermediate material, such as a foam layer, positioned under the frangible material may be included to provide a protective cushioning effect by mitigating transmission of external phenomena forces to the block. A fastening configuration at least partially enclosing other portions of the arresting unit provides a stable unified composite, without destroying desired compressive failure characteristics of the unit. Arresting units may also include a bottom layer of material stronger than the block of compressible material and a sealant coating with water resistant properties.
