Abstract : A total of one hundred and thirty tests were performed to date, and data were obtained which contribute to the evaluation of a lightweight fire extinguishing system under simulated flight conditions. Design work during this period consisted only of adapting surveillance and continuous fire detection systems to the simulated jet engine used in these tests. Testing during this period consisted of extinguishing fires created in the simulated jet engine with both conventional and lightweight extinguishing systems. The fires were created by igniting a six-gallon-per-minute spray of JP-4 jet engine fuel within the simulated jet engine. Tests were performed with air flows of 2500, 6000, and 9500 cubic feet per minute; engine skin temperatures of 200 and 550 degrees Fahrenheit and weights of Freon 13B1 (extinguishing agent) of 8, 3.7, 2.5, and 1 pounds.
