Abstract:

Since the introduction of the High-Reach Extendable Turret HRET to the Aircraft Rescue and Firefighting ARFF industry, approximately 400 HRET, have been retrofitted into existing ARFF vehicles or purchased with new ARFF vehicles worldwide. Some advantages and benefits of this technology include increased throw range performance, increased range of turret motion, more efficient agent application by applying agent at the seat of the fire, faster extinguishment of two-dimensional pool and three-dimensional flowing fuel fires, and the ability to penetrate inside an aircraft to cool the interior cabin and extinguish the fire. This added capability can increase passenger survivability, protect property, and extinguish fire faster during an aircraft postcrash incident. The purpose of this research was to document the effects of the installation of the 65-ft HRET on the predelivery inspection test of the Federal Aviation Administration FAA Striker ARFF research vehicle FAA Striker. The second key objective was to evaluate the performance and firefighting effectiveness of the 65-ft HRET in and around new large aircraft, such as the Airbus A380 and the Boeing 747-8. The findings of this research support the removal of the base turret from the design and increasing the flow rate of the tip nozzle to a selectable lowhigh flow rate of 500 and 1000 gallons.
