Aqueous Based Automatic Fire Extinguishing System

Fire Solutions LLC will demonstrate a vehicle crew fire protection system that utilizes both water mist and aqueous foam subsystems in a Phase I effort utilizing a steel simulated"Humvee"built by Naval Air Warfare Center, China Lake. The proposed crew fire protection system will function automatically even if vehicle power is disrupted, and will protect vehicle occupants against external pool fires as well as internal fire and deflagration events. Fire protection will be provided for a minimum of 10 minutes, regardless of vehicle orientationincluding rollovers. The system can be operated manually as well, with external manual activation possible for rescuers. Activation occurs upon sensing either rapid temperature rise or blast overpressure. Fire Solutions LLC water mist bottle units replace existing dry chemical and halon bottles. A minimum of 4 independent aqueous foam modules will be placed near but external to the crew compartment so that neither piping nor interior space will be required. A blast-mitigating aqueous foam patented by Sandia National Laboratories will be used in Phase I, with foam modifications to be evaluated in later phases. The single-action, patented Fire Solutions aqueous foam system requires no power and can use several agent concentrates.
