Summary
[edit]Description330-PS-3097 (USN 708767) (16769982024).jpg | 330-PS-3097 (USN 708767): New Navy Foam Fire-Fighting Truck. Mounted on a conventional crash truck, a new aircraft crash fire-extinguishing system, developed by the Naval Research Laboratory, under the sponsorship of the Bureau of Aeronautics, produces twice as much foam as previous systems. It can cover a burning airplane with approximately 15,000 gallons of a thick sticky fire-smothering blanket of foam supplied by two pumps on the truck. The improved system is the result of the new designs in nozzles and pumps with two 150-hp engines to power two separate foam-making systems. Air, water, and foam concentrate are whipped together in egg-beater fashion, and the resulting micro-bubbled foam is fleeced out through two distributing nozzles on the front fenders of the truck. These nozzles are pivoted and continuously adjustable by the operator from his position on a “bridge” above and behind the cab of the truck. By pushing a button the operator can widen his foam streams, operating a protective cone of 7,000 gallons of a foam a minute. Tanks hold 1200 gallons of water and 80 gallons of foam concentrate sufficiently for two minutes of continuous, high-capacity operation, November 10, 1952. (5/5/2015). |
