Abstract:

The development of high energy type fuels for flight vehicle propulsion systems presents new and difficult fire extinguishing problems. Small scale laboratory tests indicated that mechanical foam made with an inert gas instead of air looked promising for extinguishing some fires, particularly those involving the high energy B type fuels. The purpose of this program was to devise techniques for generating foam by inert gas injection. Two basic experimental models were fabricated consisting of A 6 gpm self contained unit capable of discharging for 5 min duration. It uses a standard N cylinder for both the pressure source and gas supply for making foam. A 60 gpm nozzle as used by the USAF was modified so that engine exhaust gas could be fed to the nozzle for foam making. A second 60 gpm system was developed to inject engine exhaust gas into the foam solution upstream of the hose leading to the discharge nozzle. Author
