Patent number: 7597502Abstract: 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.Type: GrantFiled: July 9, 2007Date of Patent: October 6, 2009Assignee: Engineered Arresting Systems CorporationInventors: Glenn Allen, Richard D.

Patent number: 6726400Abstract: Vehicle arresting beds, for installation at the ends of aircraft runways, are effective to safely decelerate aircraft entering the bed. The arresting bed is assembled of a large number of blocks of cellular concrete having predetermined compressive gradient strength, so that aircraft landing gear is subjected to drag forces effective to slow a variety of types of aircraft, while providing deceleration within a safe range of values. An arresting bed typically includes an entry region of a depth increasing from 9 to 24 inches formed of blocks having a first compressive gradient strength. A second region, which may be tapered into the first region and increase in depth to 30 inches, is formed of blocks having a greater compressive gradient strength. An aircraft thus experiences increasing drag forces while it travels through the bed, to provide an arresting capability suitable for a variety of aircraft.Type: GrantFiled: May 19, 2000Date of Patent: April 27, 2004Assignee: Engineered Arresting Systems CorporationInventors: Richard D.

Arresting units resistant to such effects are described. A block of compressible material, such as cellular concrete, provides compressive failure characteristics suitable for arresting travel of an aircraft overrunning a runway. A top sheet of 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, under the top sheet may be included to provide a protective cushioning effect by mitigating transmission of external phenomena forces to the block. A wrapping, such as polyester net, at least partially enclosing other portions of the arresting unit provides a stable unified composite, without destroying desired compressive failure characteristics of the unit.Type: GrantFiled: September 13, 2001Date of Patent: February 3, 2004Assignee: Engineered Arresting Systems CorporationInventors: Glenn Allen, Richard D.

Patent number: 5902068Abstract: Vehicle arresting blocks of cellular concrete are usable to safely slow travel of an object and may be used to construct an aircraft arresting bed at the end of an airport runway. For such purposes, cellular concrete blocks must be fabricated to exhibit compressive gradient strengths of predetermined values to provide sufficient, but not excessive, deceleration forces on an object. Material uniformity characteristics must be met to avoid unacceptable drag force variations, so that arresting blocks desirably exhibit a predetermined compressive gradient strength (e.g., a 60/80 CGS) over a depth of penetration of 10 to 66 percent of block thickness. A 60/80 CGS will typically represent an average compressive strength of 70 pounds per square inch over such depth of penetration. Prior applications of cellular concrete typically involved meeting minimum strength values and the production methods did not meet uniformity or compressive gradient strength predictability as required for arresting blocks.Type: GrantFiled: February 7, 1997Date of Patent: May 11, 1999Assignee: Datron, Inc.Inventors: Richard D.

Patent number: 5789681Abstract: Arresting material test apparatus, test probes and test methods enable testing of compressive gradient strength of cellular concrete, and materials having similar characteristics, on a continuous basis from the surface of a section to a typical internal penetration depth of at least 60 percent of thickness. Previous testing of cellular concrete typically focused on testing to confirm a minimum structural strength prior to structural failure or shattering of a test sample. For an aircraft arresting bed, for example, cellular concrete must exhibit a compressive gradient strength in a relatively narrow precalculated range continuously from the surface to penetration depth equal to 60 to 80 percent of sample thickness. Precalculated and controlled compressive gradient strength is critical to enabling an aircraft to be safely stopped within a set distance, without giving rise to drag forces exceeding main landing gear structural limits.Type: GrantFiled: February 7, 1997Date of Patent: August 4, 1998Assignee: Datron Inc.Inventors: Richard D.
