Abstract
A cable vehicle barrier (CVB) for the protection of Strategic Air Command (SAC) alert aircraft parking areas was conceived, designed and tested under a program managed by the Weapons Laboratory of the U.S. Air Force . A barrier with proven capability against vehicles and readily removable in all situations was required to support the security police and, In time, reduce manpower requirements. The CVB spans a 300 ft gap across a taxlway used by alert tankers and bombers and must be capable of being lowered quickly to meet defense or emergency vehicle needs. The barrier consists of three impact cables linked together by nylon straps, supported by posts and pulleys, and held under tension using nylon rope shock absorbers. The barrier is raised and lowered using an electric winch; a manual winch provides for adjustment and emergency operation in the event of electric winch failure. The CVB was proven in vehicle impact tests at Kirtland AFB, NM and the prototype unit has been tested operationally at Wurtsmith AFB, MI.
