    • A hook cable support assembly (10) is arranged to support a hook cable above a runway surface for arrestment of an aircraft having a tail hook. The operating mechanism of the support assembly is mounted to the detachable cover (14) of an enclosure (12). A cable support block (20) holding the hook cable can be rotated to lower the cable into a runway slot (34) for non-arrested landings and can be depressed downward upon impact by an aircraft wheel. Support block rotation is controlled by a pneumatic cylinder (60) and compression spring (70) combination acting via a four-bar linkage (50). Support block upward recovery following depression is controlled by torsion springs (46). The cylinder and compression and torsion springs are mounted to the lower surface of the cover and function as a self-contained mechanism isolated from mechanical contact with the enclosure. With this cover-mounted configuration, the operating mechanism of the cable support assembly is removable for service or replacement by detachment of the cover.

    • Vehicle arresting blocks of cellular concrete (70) 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 (70) 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 (Fig. 7). 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. Described methods include parameter, ingredient and process controls and ranges effective to enable fabrication of arresting blocks having dry densities and compressive gradient strengths which can be specified in order to provide limited deceleration of aircraft and other objects. Limited deceleration can avoid destructive effects inherent in excess rates of deceleration.

    • Vehicle arresting beds, for installation at the ends of aircarft runways, are effective to safely decelerate aircraft entering the bed. The arresting bed is assembled of a large number of blocks of cellular concrete (70) 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 (52) of a depth increasing from 9 to 24 inches formed of blocks having a first compressive gradient strength. A second region (54), 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. A protective hardcoat layer (62) of cellular concrete of strength greater than the blocks overlays the blocks to enable service personnel to walk on the bed without damage. Arresting bed systems may be provided in alternative configurations, such as a bed formed of an aggregate including pieces of cellular concrete with or without interspersed pieces of other compressible material and covered by a hardcoat layer.
