Development and Evaluation of a Prototype Wheeled Ultra-High Pressure Extinguisher System with Novec 1230

As part of an ongoing effort to identify a replacement for the Department of Defense (DOD) Halon 1211 flightline extinguisher, the Air Force Civil Engineer Center (AFCEC) developed and evaluated a prototype wheeled ultra-high pressure extinguisher containing the Novec 1230 firefighting agent manufactured by 3M. This effort expanded upon a previous evaluation of the Amerex Corporation model 775 wheeled low pressure (125 psi) extinguisher containing the Novec 1230 firefighting agent, and past projects in which AFCEC demonstrated the effectiveness of ultra-high pressure (UHP) systems using the water based Aqueous Film Forming Foam (AFFF) firefighting agent. Several ultra-high pressure hardware configurations were evaluated at pressures ranging from 550 to 2100 psi against F-100 rear engine fire tests. No combination of pressure, discharge rate, and nozzle spray pattern evaluated was effective at extinguishing both the pool fire and the nacelle fire portions of the F-100 rear engine fire test. 01 Jan 0001, 01 Jan 0001, Document contains color images
