Advances in firefighting research have brought forth new concepts that have the potential for greatly enhancing firefighting capabilities of airport fire fighters. One such concept is the high-performance, multiposition, bumper-mounted turret. The research described in this report evaluated various operating characteristics of the high-performance, multiposition, bumper-mounted turret and compared those characteristics to the roof-mounted turret. Specific items addressed included extinguishment times for various types of fires, amount of agent required for extinguishment, throw ranges, and overall performance. To investigate these items, a high-performance, multiposition, bumper-mounted turret was mounted on the Federal Aviation Administration high-performance research vehicle. This vehicle was brought to the Air Force Research Laboratory at Tyndall Air Force Base, Florida, for the comparative evaluation. Testing involved three-dimensional engine nacelle and high engine nacelle tail fires, two-dimensional pool fires, water and agent throw range tests, and turret operations. The evaluation concluded that the high-performance, multiposition, bumper-mounted turret was superior in performance to that of the roof-mounted turret. In all aspects of the evaluation, the data for throw ranges, extinguishment times, the amount of agent dispersed, and overall performance of the high-performance, multiposition, bumper-mounted turret far exceeded those from the roof-mounted turret. The high-performance, multiposition, bumper-mounted turret enabled the driver/operator to extinguish the test fires in less time and with less agent consumption than with the roof-mounted turret. |
