Abstract : The report describes a study dealing with the fire protection of large Air Force hangars. The text includes discussion of aircraft tolerance to fire exposure (by both direct flame impingement and radiative and convective heat transfer), detection systems for primary and supplementary system actuation in hangars, oscillating monitor nozzles for ground level protection in hangars, and testing of several foam agents in combination with several types of discharge devices suitable for deluge systems. The emphasis of the study was on the test program. A series of non-fire foam quality tests were conducted as well as 900 sq ft JP-4 fire tests discharging Aqueous Film - Forming Foam (AFFF) as the suppressing agent from a deluge system located 60 ft above the fuel surface.
